Apa Itu Minyak Zaitun?

Sebelum beralih ke manfaat minyak zaitun, perlu diketahui lebih dulu apa itu minyak zaitun.

Minyak zaitun adalah minyak yang terbuat dari lemak buah zaitun. Minyak zaitun termasuk minyak yang kaya akan asam lemak tak jenuh tunggal. Minyak ini banyak digunakan di negara-negara Mediterania karena pohon zaitun (Olea europaea) melimpah di kawasan tersebut.

Minyak zaitun merupakan minyak multifungsi yang bisa digunakan sebagai bahan pangan dan bahan nonpangan. Pemanfaatan minyak zaitun sebagai bahan pangan sering digunakan sebagai minyak untuk memasak dan sebagai dressing salad.

Selain itu minyak zaitun juga dijadikan sebagai obat dengan mengonsumsinya sebanyak satu gelas kecil. Pada pemanfaatan nonpangan, minyak zaitun digunakan dalam kosmetik, minyak pijat, bahan bakar lampu tradisional, dan peralatan kebersihan seperti sabun.

Daftar Manfaat Minyak Zaitun untuk Kesehatan

Minyak zaitun telah digunakan oleh banyak orang selama berabad-abad. Khasiat minyak zaitun telah dirasakan sejak dahulu baik untuk kesehatan, kecantikan, pengobatan, dan lainnya. Hingga kini telah banyak penelitian dilakukan untuk membuktikan berbagai manfaat minyak zaitun ini.

Berikut ini adalah beberapa manfaat minyak zaitun yang sayang jika dilewatkan:

1. Mengontrol Kolesterol

Manfaat minyak zaitun yang pertama adalah dapat menurunkan kadar LDL atau kolesterol ‘jahat’ dan meningkatkan HDL atau kolesterol ‘baik’ dalam tubuh.

Perlu diketahui bahwa memerhatikan kadar kolesterol dalam darah sangat penting, karena penumpukan kolesterol dapat menyebabkan terbentuknya plak pada pembuluh darah. Plak ini kemudian akan menyebabkan penyumbatan pembuluh darah yang dapat meningkatkan risiko penyakit kardiovaskular.

Khasiat minyak zaitun bisa menjaga kesehatan jantung dan juga mencegah penyakit jantung. Terdapat sebuah penelitian yang menunjukkan bahwa penyakit jantung jarang terjadi di negara-negara sekitar kawasan Mediterania.

Penelitian tersebut didukung dengan penelitian selanjutnya yang membuktikan manfaat minyak zaitun untuk mengurangi risiko penyakit jantung. Hal ini dikarenakan, minyak zaitun bisa mencegah lemak ‘jahat’ yaitu LDL dari oksidasi, meningkatkan fungsi lapisan pembuluh darah, dan mencegah penggumpalan darah.

Seperti yang sudah disebutkan sebelumnya juga, minyak zaitun dapat meningkatkan kadar kolesterol ‘baik’ atau HDL dalam darah.

3. Khasiat Minyak Zaitun untuk Mencegah Stroke

Stroke adalah penyebab kematian kedua setelah penyakit jantung yang sering ditemukan di negara-negara maju.

Stroke terjadi karena aliran darah ke otak mengalami gangguan baik karena pembekuan darah maupun adanya pendarahan. Sebuah penelitian membuktikan bahwa, kandungan asam lemak tak jenuh tunggal dalam minyak zaitun bisa menurunkan risiko stroke.

Hal inilah yang membuat kasus stroke juga jarang ditemui di negara-negara Mediterania.

4. Mengurangi Risiko Penyakit Diabetes Melitus Tipe 2

Manfaat minyak zaitun lainnya adalah bisa mengurangi risiko penyakit diabetes melitus tipe 2.

11 Proven Benefits of Olive Oil

The health effects of dietary fat are controversial.

However, experts agree that olive oil — especially extra virgin — is good for you.

Here are 11 health benefits of olive oil that are supported by scientific research.

1. Olive Oil Is Rich in Healthy Monounsaturated Fats

Olive oil is the natural oil extracted from olives, the fruit of the olive tree.

About 14% of the oil is saturated fat, whereas 11% is polyunsaturated, such as omega-6 and omega-3 fatty acids (1).

But the predominant fatty acid in olive oil is a monounsaturated fat called oleic acid, making up 73% of the total oil content.

Studies suggest that oleic acid reduces inflammation and may even have beneficial effects on genes linked to cancer (2Trusted Source3Trusted Source4Trusted Source5Trusted Source).

Monounsaturated fats are also quite resistant to high heat, making extra virgin olive oil a healthy choice for cooking.

SUMMARYOlive oil is rich in monounsaturated oleic acid. This fatty acid is believed to have many beneficial effects and is a healthy choice for cooking.

2. Olive Oil Contains Large Amounts of Antioxidants

Extra virgin olive oil is fairly nutritious.

Apart from its beneficial fatty acids, it contains modest amounts of vitamins E and K.

But olive oil is also loaded with powerful antioxidants.

These antioxidants are biologically active and may reduce your risk of chronic diseases (6Trusted Source7Trusted Source).

They also fight inflammation and help protect your blood cholesterol from oxidation — two benefits that may lower your risk of heart disease (8Trusted Source9Trusted Source).

SUMMARY Extra virgin olive oil is loaded with antioxidants, some of which have powerful biological effects.

3. Olive Oil Has Strong Anti-Inflammatory Properties

Chronic inflammation is thought to be a leading driver of diseases, such as cancer, heart disease, metabolic syndrome, type 2 diabetes, Alzheimer’s, arthritis and even obesity.

Extra-virgin olive oil can reduce inflammation, which may be one of the main reasons for its health benefits.

The main anti-inflammatory effects are mediated by the antioxidants. Key among them is oleocanthal, which has been shown to work similarly to ibuprofen, an anti-inflammatory drug (10Trusted Source).

Some scientists estimate that the oleocanthal in 3.4 tablespoons (50 ml) of extra virgin olive oil has a similar effect as 10% of the adult dosage of ibuprofen (11Trusted Source).

Research also suggests that oleic acid, the main fatty acid in olive oil, can reduce levels of important inflammatory markers like C-reactive protein (CRP) (2Trusted Source3Trusted Source).

One study also showed that olive oil antioxidants can inhibit some genes and proteins that drive inflammation (12Trusted Source).

SUMMARYOlive oil contains nutrients that fight inflammation. These include oleic acid as well as the antioxidant oleocanthal.

4. Olive Oil May Help Prevent Strokes

Stroke is caused by a disturbance of blood flow to your brain, either due to a blood clot or bleeding.

In developed nations, stroke is the second most common cause of death, right behind heart disease (13).

The relationship between olive oil and stroke risk has been studied extensively.

A large review of studies in 841,000 people found that olive oil was the only source of monounsaturated fat associated with a reduced risk of stroke and heart disease (14Trusted Source).

In another review in 140,000 participants, those who consumed olive oil were at a much lower risk of stroke than those who did not (15Trusted Source).

SUMMARYSeveral large studies demonstrate that people who consume olive oil have a much lower risk of stroke, the second biggest killer in developed countries.

5. Olive Oil Is Protective Against Heart Disease

Heart disease is the most common cause of death in the world (16).

Observational studies conducted a few decades ago showed that heart disease is less common in Mediterranean countries.

This led to extensive research on the Mediterranean diet, which has now been shown to significantly reduce heart disease risk (17Trusted Source18Trusted Source).

Extra virgin olive oil is one of the key ingredients in this diet, protecting against heart disease in several ways (19).

It lowers inflammation, protects “bad” LDL cholesterol from oxidation, improves the lining of your blood vessels and may help prevent excessive blood clotting (20Trusted Source21Trusted Source22Trusted Source23Trusted Source24Trusted Source25Trusted Source).

Interestingly, it has also been shown to lower blood pressure, which is one of the strongest risk factors for heart disease and premature death. In one study, olive oil reduced the need for blood pressure medication by 48% (26Trusted Source27Trusted Source28Trusted Source).

Dozens — if not hundreds — of studies indicate that extra virgin olive oil has powerful benefits for your heart.

If you have heart disease, a family history of heart disease or any other major risk factor, you may want to include plenty of extra virgin olive oil in your diet.

SUMMARYExtra virgin olive oil has numerous benefits for heart health. It lowers blood pressure, protects “bad” LDL cholesterol particles from oxidation and improves the function of blood vessels.

6. Olive Oil Is Not Associated With Weight Gain and Obesity

Eating excessive amounts of fat causes weight gain.

However, numerous studies have linked the Mediterranean diet, rich in olive oil, with favorable effects on body weight (29Trusted Source30Trusted Source31Trusted Source).

In a 30-month study in over 7,000 Spanish college students, consuming a lot of olive oil was not linked to increased weight (32Trusted Source).

Additionally, one three-year study in 187 participants found that a diet rich in olive oil was linked to increased levels of antioxidants in the blood, as well as weight loss (33Trusted Source).

SUMMARYConsuming olive oil does not appear to increase the likelihood of weight gain. Moderate intake may even aid weight loss.

7. Olive Oil May Fight Alzheimer’s Disease

Alzheimer’s disease is the most common neurodegenerative condition in the world.

One of its key features is a buildup of so-called beta-amyloid plaques inside your brain cells.

One study in mice showed that a substance in olive oil can help remove these plaques (34Trusted Source).

Additionally, a human study indicated that a Mediterranean diet rich in olive oil benefitted brain function (35Trusted Source).

Keep in mind that more research is needed on the impact of olive oil on Alzheimer’s.

SUMMARYSome studies suggest that olive oil may combat Alzheimer’s disease, but more research is needed.

8. Olive Oil May Reduce Type 2 Diabetes Risk

Olive oil appears to be highly protective against type 2 diabetes.

Several studies have linked olive oil to beneficial effects on blood sugar and insulin sensitivity (36Trusted Source37Trusted Source).

A randomized clinical trial in 418 healthy people recently confirmed the protective effects of olive oil (38Trusted Source).

In this study, a Mediterranean diet rich in olive oil reduced the risk of type 2 diabetes by over 40%.

SUMMARYBoth observational studies and clinical trials suggest that olive oil, combined with a Mediterranean diet, can reduce your risk of type 2 diabetes.

9. The Antioxidants in Olive Oil Have Anti-Cancer Properties

Cancer is one of the most common causes of death in the world.

People in Mediterranean countries have a lower risk of some cancers, and many researchers believe that olive oil may be the reason (39Trusted Source).

The antioxidants in olive oil can reduce oxidative damage due to free radicals, which is believed to be a leading driver of cancer (40Trusted Source41Trusted Source).

Many test-tube studies demonstrate that compounds in olive oil can fight cancer cells (42Trusted Source43Trusted Source).

More research is needed to determine whether olive oil in fact reduces your risk of cancer.

SUMMARYPreliminary evidence suggests that olive oil may reduce cancer risk, but further studies are needed.

10. Olive Oil Can Help Treat Rheumatoid Arthritis

Rheumatoid arthritis is an autoimmune disease characterized by deformed and painful joints.

Though the exact cause is not well understood, it involves your immune system attacking normal cells by mistake.

Olive oil supplements appear to improve inflammatory markers and reduce oxidative stress in individuals with rheumatoid arthritis (44Trusted Source45Trusted Source).

Olive oil seems particularly beneficial when combined with fish oil, a source of anti-inflammatory omega-3 fatty acids.

In one study, olive and fish oil significantly improved handgrip strength, joint pain and morning stiffness in people with rheumatoid arthritis (46Trusted Source).

SUMMARYOlive oil can help reduce joint pain and swelling from rheumatoid arthritis. The beneficial effects are greatly increased when combined with fish oil.

11. Olive Oil Has Antibacterial Properties

Olive oil contains many nutrients that can inhibit or kill harmful bacteria (47Trusted Source).

One of these is Helicobacter pylori, a bacterium that lives in your stomach and can cause stomach ulcers and stomach cancer.

Test-tube studies have shown that extra virgin olive oil fights eight strains of this bacterium, three of which are resistant to antibiotics (48Trusted Source).

A study in humans suggested that 30 grams of extra virgin olive oil, taken daily, can eliminate Helicobacter pylori infection in 10–40% of people in as little as two weeks (49).

The health benefits of olive oil

Discover the nutritional benefits of olive oil, which vitamins it contains, and what makes extra virgin olive oil the healthiest type to buy.

What is olive oil and how is it produced?

Olive oil is the liquid fat, or natural oil obtained from pressing whole olives. Different olives, from different countries, will each give the oil a different taste – some quite mild, and others quite peppery or bitter.

Different processing techniques will result in olive oils of different ‘grades’ – refined and unrefined.

Unrefined oils are pure and untreated, meaning that no chemicals or heat have been used in the extraction process, resulting in a purer oil with a stronger taste. Refined oils have been treated to remove any flaws and are usually lighter in colour and milder in taste.

Extra virgin olive oil is an unrefined oil made from pure, cold-pressed olives and is usually more expensive, as it’s deemed the highest quality. It has a stronger flavour and is typically darker in colour compared to other olive oils.

Other, regular or light, olive oils are usually a blend of both cold-pressed and processed oils.

Nutritional profile of olive oil

Olive oil is 100% fat. One 15ml (1 tbsp) serving contains around 135 calories, and on average 14g of fat of which 2g are saturated and the rest is unsaturated fats.

Around 75% of this fat is a mono-unsaturated fat, called oleic acid, or omega-9, which is associated with multiple health benefits. The rest is poly-unsaturated fats, known as omega-6 and omega-3.

Olive oil contains vitamin E, which supports the normal function of the immune system as well as maintaining healthy skin and eyes, and is a good source of vitamin K, which is needed for blood clotting and wound healing.

It’s the oil’s antioxidant status which provides a lot of its nutritional value, graded using the ORAC (Oxygen Radical Absorbance Capacity) scale. Dietary antioxidants are found in foods and have been shown to significantly improve health. Extra virgin olive oil typically has a higher ORAC scale than refined olive oil.

Can olive oil improve heart health?

Olive oil is a key component of the Mediterranean diet, and there’s been plenty of research that demonstrates the benefits of olive oil, in particular extra virgin olive oil, for heart health. This includes its ability to reduce blood pressure and improve healthy cholesterol levels, both of which contribute to a reduced risk of heart disease.

A large review of some of these studies demonstrated how olive oil was the only source of monounsaturated fat that’s been associated with a reduced risk of both stroke and heart disease.

Can olive oil reduce inflammation?

Inflammation is thought to be one of the key drivers behind some of the world’s more chronic health problems, including Alzheimer’s and Type 2 diabetes. Research looking at the role of antioxidants and their anti-inflammatory effect, including oleic acid found in olive oil, has discovered they play a role in reducing inflammation and the marker for inflammation known as C-Reactive Protein (CRP).

Some studies have even found that extra virgin olive oil contains an antioxidant compound called oleocanthal, which shares the same pharmalogical activity as ibuprofen, thereby acting as a natural anti-inflammatory.

Part of this anti-inflammatory role has also been associated with certain positive changes in immune function in those with rheumatoid arthritis.

Can olive oil improve mood?

As part of a healthy diet (one that includes high intake of fruit and vegetable and oily fish) olive oil has been found to play a role in decreasing the risk of depression.

2015 study found that in older populations, a Mediterranean diet supplemented with olive oil or nuts was associated with improved cognitive function, and there’s been more studies into how it may reduce the risk of Alzheimer’s.

Other early research has suggested that olive oil may have protective effects against Type 2 diabetes and some forms of cancer – however more research is needed before we can draw any firm conclusions.

Does heating olive oil make a difference to its nutritional profile?

There is some debate around this as it’s traditionally thought that extra virgin oil was more sensitive to heat and had a lower ‘smoke point’ – once an oil reaches its smoke point it begins to change in chemical structure and may become a transfat. A 2018 study found that both extra virgin and regular olive oil both had good smoke points and are therefore fine to cook with.

As extra virgin olive oil is more expensive and has a stronger, more peppery taste it may be best kept for drizzling and dipping rather than cooking with. Refined olive oils, such as light olive oil, are much cheaper and have little or no taste which means it won’t affect the flavour of whatever you are cooking.

How can I buy the best olive oil?

Ideally, buy olive oil in a dark bottle, especially extra virgin olive oil, as light degrades the oil and can turn it rancid. This also means it’s best to store your olive oil in a cupboard and not on the kitchen surface where it can be exposed to sunlight. Dark glass bottles or stainless steel containers offer better protection than plastic bottles.

Check the ‘best by’ date and if you see ‘harvest date’ or ‘pressed on’ date, it’s likely to be a higher quality oil.

Different regions and oils will produce different tastes so often this is just down to preference.

Olive Oil: The Magic of Nature

Olive oil is lovingly called liquid gold owing to its properties. That’s how Homer, the Greek poet referred to it. Did you know that Olive trees were so revered that it was considered an offense to cut them down as per the Laws of Solon? The oil was frequently used in religious rites. It was also used to make medicines and cosmetics. The oil was also used in culinary preparations.

It is believed that olives got their name from the word “el’yon” of Semitic-Phenician origin. The term was used in comparing the oil with the vegetable and animal fats used at that time. Interestingly enough, the Romans extracted olive oil using a screw-press method that is still used to this day around the world.

The oil is also known for its antibacterial properties and is also a very potent cleanser and moisturizer. It is also widely used as a massage oil. Did you know that Spain is the largest producer of Olive Oil? Italy and Greece are major producers too.

Historical Uses of Olive Oil

Olive oil is linked with Greek mythology too. It is believed that Athena, the Greek goddess, gifted the Olive tree to the region. The Greeks preferred the tree to the gift of Poseidon, a saltwater spring that arose from a cliff.

The Greeks believed that the oil was an essential part of religious ceremonies. It was also used for lighting, culinary uses, and in medicinal preparations. The religious literature of the region also mentions olive oil and its many uses. They also consider olive as an expression of peace and cosmic blessings. From this arose the popular phrase “extending an olive branch”. So you see, the olive tree has been very significant culturally. The olive tree is also considered a symbol of strength, beauty, and prosperity.

The tree grows for nearly 400 years and is highly respected in the Mediterranean region. We do not yet know much about the exact origins of the tree but some believe that it was first cultivated on Crete as well as the other Greek islands some 7000 years ago. Most people, however, believe that olive oil traces its origins to the Near East. The Olive tree reached the Mediterranean region as it was popularized by the Egyptian, Roman, Greek, and Phoenician cultures.

It is said that Portuguese and Spanish explorers brought the Olive trees to the West in the 1400s and 1500s. The Franciscan missionaries brought Olive groves to California in the latter part of the 18th century. Today, the areas near the Mediterranean Sea are the best for the growth of Olive trees owing to their climate and soil.

Outside the Mediterranean region, the nations that produce Olive oil in large amounts include Chile, Argentina, South Africa, Southwestern USA, New Zealand, and Australia.

Homer, the Greek poet called Olive oil the “liquid gold”. In fact, it was so respected that those who cut down Olive trees were sentenced to death as stated in the Greek Laws of Solon from the 6th and 7th centuries. It is also believed that the royal Olive groves of King David were well guarded round the clock, as were the Olive Oil warehouses.

It so happened that Olive oil became one of the most traded items when the Roman Empire spread its influence across the Mediterranean region. There was major commercial progress at this time. Pliny the Elder in his accounts mentions that Italy had great quality Olive Oil by the 1st century AD which was then considered the best of its kind in the region.

The Romans, it is believed, used Olive Oil in the manner of a body moisturizer. They used it to hydrate the skin and lock moisture after bathing. Olive oil was also a frequently gifted item. The Romans also invented the screw-press technique that helped in the extraction of the oil and is still used in many regions across the world.

It is also believed that the Spartans and Greeks used Olive Oil as a moisturizer in gymnasia so as to enhance the muscular shapes of their forms. The athletes in the ancient times were given massages with oils that had Olive Oil blended in to heal sports injuries, relax muscles, and prevent the accumulation of lactic acid. The ancient Egyptians also used the oil as a strong antibacterial agent, a skin moisturizer, and a cleanser.

Many believe that the Greek name of the Olive tree itself establishes its values and benefits. The name is considered to be derived from the word “el’yon” of Semitic-Phenician origin that means “superior”. This very name was used across trade networks and more often when Olive Oil was compared with the other vegetable and animal fats of the time.

The Chemical Constitution of Olive Oil

Olive Oil derives its properties from its many chemical constituents. Let us now study these compounds in detail and see their specific benefits.

Olive oil’s composition varies depending on the quality and variation of the Olive fruit that is used in its extraction. It also depends on the region from where the fruit has been sourced, the altitude, the harvest time, the climate at the time of growth, as well as the process used for extraction.

That said, three essential compounds always present in Olive oil include Linoleic acid, which makes up 21% of the oil, Palmitic acid, which makes nearly one-fifth of the oil, and Oleic acid that comprises about 83% of the oil.

Let us now discuss the variations between the different varieties of Olive oil.

Extra-Virgin Olive Oil: 

This is basically natural, pure Olive oil or one could argue, Olive juice. It has undergone the least amount of processing. This is because it is extracted through a cold-pressing process and no chemicals are used to refine the oil.

Since high amounts of heat are not used to extract Olive oil in this technique, the nutrients and compounds present in the oil are retained. This ensures that the natural constitution is maintained and so are the health benefits.

Extra-virgin olive oil is thus a premium variety of the oil. In fact, the word “extra” in the name symbolizes that the oil is of exceptionally high quality.

Virgin Olive Oil:

Virgin Olive oil is obtained by the second pressing once the extra-virgin variety has been obtained from olives. Like the extra-virgin variant, the virgin variety is also obtained using simple cold-pressing using mechanical devices. One of the main drawbacks of this variant is that it uses a poorer quality of the fruit in comparison to the extra-virgin variety.

Ordinary Virgin Olive Oil:

Ordinary virgin olive oil is also extracted from the fruit using mechanical means only. Sometimes, thermal methods are also used but care is taken that the oil’s properties are not altered. This process involves washing, decanting, centrifuging, and filtering the oil.

The oils that are extracted using solvents or methods involving re-esterification as well as the oils that are mixed with oils from different sources are not put into the category of Ordinary Virgin Olive oil. The Oleic acid content is 3.3% which makes them lower in quality.

Refined Olive Oil:

Sometimes chemical treatment is used to extract the oil. In this method, the acid content and unwanted properties like the strong odors are taken out with the help of chemicals or charcoal. These help to neutralize these traits.

The refined variety is also called pure olive oil or just olive oil by some companies.

Olive Pomace Oil:

This variety of olive oil is extracted from the pomace which is the “mash” which means the skin, seeds, stem, and pulp of the olives that remain after virgin olive oil has been extracted from the olive fruits. The oil that is obtained is very small in quantity and simple pressing does not yield a lot of oil.

Thus, to extract it, chemical solvents and high heat are used to extract the oil. This includes the use of chemicals such as hexane.

Benefits of Olive Oil

Owing to the ability of olive oil to cleanse, moisturize, and deeply penetrate the tissues, the oil can be applied to the skin and used in a massage. It is also known to prevent injuries during workouts, sports, muscle aches, and joint pain. It helps to eliminate the accumulation of lactic acid.

It also contains antioxidant properties and reduces premature signs of aging from the skin. It restores smoothness in the skin and forms a barrier that guards against the harmful UV rays of the sun. It also helps to prevent damage to the skin by free radicals. It can be added to compounds that are abrasive and used as an exfoliating agent that will make the skin look rejuvenated, radiant, and soft.

Olive oil is also a great makeup remover and can remove very stubborn products from the skin. It also has moisturizing properties that help to make the skin soft and smooth. It is also used in shaving creams and is applied as an aftershave.

It is also used in manicures and applied to the cuticles to soften and moisturize them. It is also used to make facial masks. People with skin that is prone to acne or skin that is sensitive can also use olive oil to prevent dryness. Olive oil hydrates the skin and prevents the growth of acne-causing bacteria.

It is used to prevent hair damage as it forms a protective sheet on the hair to protect them from the damage caused by external pollutants. Olive carrier oil makes hair skin smooth, healthy, and strong.

Let’s now discuss the medicinal uses of olive oil. Olive carrier oils have antimicrobial and anti-inflammatory phenols that protect the skin from getting infected by harmful bacteria and help the skin to heal. It also provides relief to sore and bruised skin and is also used to provide relief from muscle and joint pains that are caused by arthritis or sprains.

It helps to heal the skin that is damaged by the harmful rays of the sun and gives a radiant and youthful appearance to it.

The oil also has therapeutic benefits. Let us see these now.

Cosmetic: Emollient, Antioxidant, Skin Brightening, Collagen Boosting, and Cleansing

Medicinal: Antibacterial, Anti-Inflammatory, Stimulant, Regulating, and Detoxicant

How is Olive Oil Cultivated and Harvested?

Dating back to the 8th millennium, Olive trees were found all around the Mediterranean basin. The largest producers of olive oil include Italy, Spain, and Greece. These are evergreen trees and have a long lifespan. Some even live up to a thousand years.

Great Olive yields are produced in alternative years as a good yield depletes the natural resources leading to a lighter yield in the next year. Owing to this reason, the trees are planted in a way that alternate breeding is implemented.

Olives pollinate themselves but the growth can be increased by using pollinator trees, especially when the weather is not suitable.

The trees do not need specific conditions for their growth and are pretty forgiving. They are grown on steep hillsides and can even grow in poor soil and in an area with low water levels. If the temperature falls below -5 degrees Celsius, the small branches of the trees are damaged and the large branches will die if the temperature drops below -9 degrees Celsius.

There are some varieties of Olives that are more sensitive to cold compared to the others. However, there is no variety that is completely resistant to cold weather. Care should be taken that the tree is not kept in freezing temperature before harvest, otherwise, the crop will be damaged.

Olive trees grow best in lean soil. Lean soil has very low quantities of nutrients and they can also grow in soil that is well-drained. Olives can also grow in soils that have different pH levels that range between 5 and 8.5. However, the optimal pH level for growth is 6.5.

They will not prosper in highly fertile and deep soil. Olive trees require adequate drainage for their growth and they cannot withstand excessive moisture. Young trees need more water to yield fruits in minimal time.

When the blooming period is underway, olive trees will need dry conditions so that the fruits set well. For the development of the flower, olive trees need some chilly temperature that reaches about 7 degrees Celsius. They will not grow in tropical or semi-tropical areas as the heat will not allow proper flower formation. The requirement of the chill temperature varies from one variety to the other.

In the traditional method, olives are cultivated through the technique of dry farming. It does not make use of irrigation and is mostly used in drylands. Irrigation allows the trees to bear fruits much sooner. When properly irrigated, the tree bears fruits within 8-10 years of cultivation. Otherwise, it bears fruits in 20-30 years.

Olives that are edible are called table olives and need large amounts of water to increase the size of the fruit. On the other hand, the olives that are cultivated to extract the oil require less amount of water.

In the month of October and after December, olives are harvested mechanically, manually, or by combining both the methods. A trunk shaker is used for mechanical harvesting. It puts its arms around the trunk of the olive tree and shakes the tree and the mature olives fall to the ground.

Olives, on maturation, turn black. However, when the olives are totally green, they are also considered mature. There is a huge range of olive carrier oil colors which mostly are mixtures of green and ripe olives.

Ripe green olives are picked in the development stage where the juice of the olive turns milky. The olives that will be used for extracting oil are left on the tree so that they change their color. They can also be picked when they are green in color and then allowed to transform themselves into black color while processing.

Green olives produce oil which is peppery, smells pungent, bitter, and is herbaceous. Ripe olives have an aroma that is mild and buttery. The young olives are beaten manually to detach them from their branches and they are captured in a net which resembles an inverted umbrella and prevents the olives from falling to the ground. If the olives hit the ground, their aroma will be affected.

From the net, the olives are taken to the collection device. When the fruits are beaten, some of them have their skin bruised which affects the aroma of the oil. The oxidation of the olives can be prevented if they are sent to the mill within an hour of being collected from their trees. Ideally, the processing should start within 24-hours of the fruit collection. If they are left in the bins, they will deteriorate and begin to decay. This will cause the oil to smell musty.

The Extraction Process of Olive Oil

In the process of extraction, firstly, the twigs, stems, leaves, and any remaining dirt need to be removed. Then, the olives are washed to eliminate contaminants and pesticides. The next process involves the olives being ground into a paste. A hammer mill, stone mill, or a metal tooth grinder is used to grind the olives. This will tear the flesh of the olives and make the release of the oil easy.

The next process is malaxation. In this process, the paste is stirred continuously for approximately 45 minutes in a warmed tank. All the small droplets of oil will combine to form big drops. Then the oil is separated from the fruit, water, and solid matter.

In the modern method, a centrifugal decanter is used, wherein, the paste is spun rapidly and the oil is separated from water and the solids. A second centrifuge is done to remove any remaining impurities. The oil is left in the tank or barrels so as to settle. This is called racking. Finally, the oil is filtered and bottled.

Like all other carrier oils, olive oil also deteriorates on aging and also when it is exposed to light, heat, and air. For its long life, it should be stored in a dark bottle of glass away from light. The polyphenol content present in the oil contributes to the shelf life of the oil. The higher the level, the more stable will be the oil.

The oil that is derived from the olives that are harvested earlier has an increased level of polyphenolic components and lasts approximately 2 years. On the other hand, the olives that are picked in a late harvest will yield an oil that is low in polyphenolic content. This oil will turn rancid sooner. If left unopened and well stored, it’s life can be up to 1 year. For the further refining of olive carrier oil, it can be processed which will reduce the acidity by the use of steam processing or caustic soda. The oil is bleached with activated carbon or synthetic Silica treatment which will reduce the presence of residual fatty acids, chlorophyll, pesticides, and carotenoids.

Processing of the oil with activated carbon will reduce its aroma.

The Everyday Benefits of Olive Oil

There are numerous benefits of Olive carrier oil that range from cosmetic to medicinal. It is used in lotions, oils, soaps, gels, candle-making, and shampoos. Olive oil can be applied directly on the skin or it can be mixed into a moisturizer and then applied on the skin to hydrate it. It will also increase the effectiveness of the moisturizer.

Olive oil has soothing properties and can be used on irritated, inflamed, or dry skin. Organic olive carrier oil is a good bedtime serum and can be applied to the face and neck. During the daytime, olive oil should be applied and left on the skin for approximately 15 minutes. Wash it thoroughly. It is also useful on sunburnt or skin that has been exposed to the sun.

Olive carrier oil can be applied to the skin before or after shaving. After shaving, it acts as an aftershave. Olive oil is a very good makeup remover and carries with it all the pollutants, blackheads, and dirt. For a steam facial, olive oil is mixed with an equal amount of castor oil and massaged to the facial skin. Then, rinse the skin with warm water which will help to clean the pores.

To use the oil as a makeup remover, add 1-2 drops of extra virgin olive oil to a cotton pad and wipe across the face gently. It can remove the most stubborn makeup. It can also be used as a pre-cleanser.

It is also used to exfoliate the skin by mixing it with a small quantity of sea salt. Massaging the area of the skin that is scaly and dry will make it look young and new. Instead of salt, sugar can also be used. Sugar will remove the dead cells of the skin and the oil will penetrate deep into the skin, allowing it to look more polished and radiant.

Olive carrier oil is also known to treat split ends and frizzy hair. It is also known to cure dandruff. It can be used in a hair treatment mask by mixing an egg yolk into it and squeezing some drops of lemon juice into it. Apply this mixture from the roots to the tips. Allow it to remain for 15 minutes and then wash with shampoo and conditioner. This leaves the hair lustrous, soft, and silky.

You can also apply olive carrier oil directly without mixing lemon juice and egg yolk. Just heat the oil a little and apply to the hair and allow it to remain for an hour. It also prevents the nails from cracking and drying. This will prevent the growth of bacteria and fungi. Olive oil when applied to the nails will keep the cuticles soft.

Apply one drop to the cuticles before bedtime. This will help the nails to grow healthy and will keep them hydrated. Nails can be soaked in warm olive carrier oil two times a week to increase their gloss and strength. For complete relief, mix extra virgin olive oil with warm bathing water. This will help to repair the skin, increase its elasticity, and slow down the signs of aging as olive oil has antioxidant properties.

You can massage the body with olive carrier oil and then take a warm bath. This will make the body soft and smooth. Olive oil can be used as a body lotion after bathing to make it soft, shiny, and smooth.

Precautions When Using Olive Oil

Remember that you should never ingest carrier oils. They are for external use only. Olive oil should not be applied to sensitive skin or if you’re suffering from dermatitis as it can worsen the situation. Conducting a patch test on the skin is highly recommended. To conduct a patch test, apply a pea-sized amount of the oil on the inner arm and leave it for 24-48 hours.

If no allergic reactions appear, it proves that the oil is safe for use on your skin. Olive carrier oils should never be applied to infants as research has shown that when applied directly to the baby’s skin, it might cause eczema, particularly if there is a history of skin problems in the family.

People who suffer from asthma, hay fever, or atopic dermatitis should abstain from the use of olive oil as it may increase allergic reactions. Because of the heavy nature of olive carrier oil, it is advised that excess oil should be wiped off with cotton wool from the skin after application to prevent the clogging of pores and trapping bacteria.

Pregnant and lactating women should not use the oil before consulting their doctors first. Before using olive carrier oil, always consult your healthcare practitioner as he will be the best person to advise.
