Palm oil: properties and uses
Palm oil is not as unhealthy as some experts say. To find out in what area it is used, what is the main benefit of eating it, you need to understand this topic in more detail.
What is it and how is it made?
Palm oil is an excellent substitute for sunflower oil, in addition, it is also used in the diet. It is an excellent source of energy and vitamins that are hard to find in other foods. Palm oil has been used for 3,000 years, and archaeologists have found traces of it in Egyptian tombs. For thousands of years, merchants have been supplying this product all over the world. It is believed that initially this product was imported to Egypt by the Arabs, who brought it from Africa.
Trade in this ingredient was widely represented in the British Empire, after which a real industrial revolution took place., which expanded the scope of palm oil in the international market. It has become a raw material for many industrial activities and has also been used as the basis for the manufacture of candles and lubricants throughout Europe.
The wide scope of use of the product aroused great interest among investors, so they began to invest a lot of money in the production of the product. Many industries have been able to reach a new level of development thanks to its use.
Palm oil is high in fat, which is why even at room temperature it remains solid and can withstand extreme heat. Many modern products contain this component, as it is a cheap substitute for other natural oils, which can reduce production costs.
Many cosmetic companies use it in their soap making. Palm oil provides the desired texture, although it also lacks many of the important compounds that make personal care products beneficial to the skin.
In 2007, palm oil became one of the most popular around the world. It is produced in many countries in Africa and Asia, as well as Latin America. Local residents use it as a cheap and high-quality source of fuel, heat and lighting. After the demand for the product began to grow rapidly, its cost skyrocketed.
To extract the oil, the fruits of the plant are harvested and pressed. As a result of this cold pressing, a dark red product is obtained, in which the content of a substance called carotene is high. When it is subjected to heat processing, carotene breaks down. Manufacturers sell pure oil or use a fractional distillation process to extract individual components from it, which are then used in various industries.
Compound
Palm oil consists mainly of triacylglycerols. Other components are acids, moisture.
Triacylglycerol is the basic unit of oils and fats. The type of acid determines the product itself, endowed with special characteristics. It is a chemical compound consisting of three elements:
- carbon;
- hydrogen;
- oxygen.
Acid and glycerol molecules combine to form triacylglycerol.
Fatty acids are:
- short chain with aliphatic tails of less than six carbon atoms;
- medium chain with tails of 6-12 carbon atoms;
- long-chain with tails from 13 to 21 atoms;
- very long chain with more than 22 carbons.
One of the main parameters affecting the characteristics of oils is the degree of unsaturation of acids. They can be saturated, monounsaturated or polyunsaturated. Palm oil contains the following acids:
- lauric;
- myristic;
- palmitic;
- stearic;
- oleic;
- linoleic;
- α-linolenic.
This complex, from a chemical point of view, fatty acid product differs from other oils in its high content of palmitic acid. It also contains almost equal amounts of saturated (palmitic 45% and stearic acid - 4%) and unsaturated acids (oleic - 40% and linoleic - 10%).
During storage and transportation, care should be taken to ensure that moisture or metal salts (especially copper or bronze) do not get into the oil, as they activate hydrolysis. That is, the substance reacts with water and in this process breaks down into new compounds.
Freshly pressed, unprocessed palm oil contains about 1% carotenoids, tocopherols, tocotrienols, styrenes, phospholipids, triterpene alcohols, squalene, aliphatic alcohols and aliphatic hydrocarbons. The main components of industrial interest are carotenes, tocopherols, tocotrienols, sterols and squalene. Carotenes and tocopherols are antioxidants, they stabilize the oil and protect it from oxidation.The process of refining, bleaching and steam deodorization partially removes some of the valuable compounds. Their residual amount depends on the processing conditions.
The dark red-orange color of the oil palm fruits is due to the high concentration of carotenoids and anthocyanins. The main components are α-carotene and β-carotene.
Palm oil contains styrenes. Phytostyrenes have been the subject of discussion by many nutritionists due to their bioactivity. The content of phytostyrenes in the described product is relatively lower than in other oils. The main source of phytostyrenes in large-scale production are by-products of the processing process. For example, a distillate of fatty acids.
The product contains phospholipids and glycolipids, which are almost completely removed during the refining process, so their amount in it at the end of the processing process is very low.
What is useful?
For frying, palm oil is one of the best options. It is a very common ingredient used in African and Asian cuisine. The benefits for the human body from the use of this product are invaluable, but in order to understand what it is, its properties must be considered in more detail.
Food is the most important source of energy, but some foods don't provide as many nutrients.to provide a lasting boost of strength, and in the long run they are even harmful to health. For example, eating a lot of sweets can cause diabetes with age, but for a short period of time it is a wonderful source of energy.In contrast, palm oil is an excellent source of nutrients that provides a long-lasting boost of energy, its composition gives the body all the necessary nutrients that it needs. Beta-carotene helps balance hormone levels.
A diet rich in antioxidants is cancer prevention. Palm oil contains tocopherols, which are compounds that target cancer cells.
In recent years, more and more people suffer from the formation of blood clots in the vessels and veins. Small plaques not only interfere with the flow of blood to the organs, but can also cause a stroke, instant death. Researchers have proven that the use of palm oil as a food supplement is a fairly effective prevention against thrombosis. It contains fats:
- saturated;
- unsaturated.
This type of oil, when used in moderation, helps to balance cholesterol levels, helping to cleanse the body of it.
The product is rich in beta-carotene, a nutrient that not only helps in cancer prevention, but also plays an important role in building a healthy and strong immune system. It strengthens the body from the inside, helping it fight disease. The beta-carotene in palm oil is a derivative of the vitamins present in it.
Healthy gut bacteria, which come from vitamin K intake, are essential for everyone, but their numbers can decrease with age or due to illness or medication.People suffering from a deficiency of this substance are also resistant to antibiotics, respectively, their use does not have the desired positive effect. As part of the described product, vitamin K is concentrated in large quantities, but you should not abuse it.
Moreover, omega-3 fatty acids are a powerful substance that helps in maintaining a healthy muscle structure. Palm oil contains enough omega-3s to slow the loss of cognitive function in Alzheimer's patients. It is also very useful in the fight against arthritis and similar diseases.
The secret of youth is vitamin E, which must be additionally consumed in old age. It protects the skin and body from oxidative reactions caused by free radicals. The high content of vitamin E in palm oil ensures the regeneration of skin cells, protects the heart and other vital organs from aging.
During pregnancy, the right choice of food consumed is important not only for the mother, but also for the child., the growth and development of which depends on the nutrients consumed by the expectant mother. Vitamin deficiency can adversely affect the development of the unborn child. Palm oil contains vitamins D, K, E and A, which are very useful and necessary during this period.
Vitamin D deserves special attention, the deficiency of which is experienced by every third person in our country. Its best source is the sun, but the modern way of life does not always make it possible to spend a lot of time in nature and just on the street, which inevitably leads to its deficiency. As a result, a person suffers from inflammation in the joints and arthritis.Palm oil is a good source of vitamin D, which also helps the body absorb calcium in the body.
Harm
There is an active debate about whether palm oil is harmful to humans. Many scientists boldly declare that it is dangerous during pregnancy, for newborns, because it contains a carcinogen that cannot be removed from the body.
Indeed, despite the huge number of advantages, this product has one big drawback - indigestibility by the body, as well as the content in it of such a substance as stearin, which melts at temperatures above 47 degrees. Accordingly, it cannot be removed from the body, and its gradual accumulation negatively affects the human body, leads to damage to blood vessels, the release of free radicals, which becomes an excellent soil for the formation of cancer cells.
This product cannot be used for food every day, as there are developments of the following pathologies:
- weakening of the immune system;
- accumulation of bad cholesterol;
- diabetes;
- atherosclerotic deposits;
- overweight.
The negative impact of palm oil on people who have a poor metabolism has been proven. It is not advised to use it and products with its presence while feeding a newborn, which is a danger to his immune system.
What products contain?
In the modern world, there are a lot of goods on the shelves of modern stores that have palm oil, and these are not only cosmetics, soaps and shampoos, but also food. Increasingly, this cheap substitute is being used in candy, powdered milk formulas, desserts, and other products.With all this, not every manufacturer is ready to indicate on the packaging that palm oil is present in the composition, since a negative attitude towards it reduces the demand for products. In addition, it can be found in ice cream and instant noodles.
Today, two states are engaged in extensive supplies of the product to the market - Indonesia and Malaysia, which sell tens of millions of tons of oil annually. It is actively bought by the cosmetic and food industries. The oil is widely used in the manufacture of lipstick, because it holds color well, has no aftertaste and does not melt in the heat.
From the external use of products that contain this oil, there is no harm, so you can safely buy personal care products and cosmetics.
Application
The extensive scope of application made the product in demand. It is used in food production, cosmetics, and lubricants.
The acids in which the product is rich are widely used in animal feed or sold for the production of specialty chemicals, including face and body creams. Today, the truth is that every brand of shampoo and hair conditioner we know that we see in stores uses this ingredient, but the substance is hidden under various names.
The consumer should be aware that just because palm oil is honestly indicated on the label by the manufacturer, it does not mean that all other products in this category are free from it. Before this ingredient was used, petrochemistry and animal fats were used, including in cosmetology, which are even more difficult to remove from the body.
There are several reasons why oil is widely used in food production, regardless of the fact that it can harm the human body in large quantities. The main one is that it is cheap, and thus manufacturers can save a lot on production. Due to pressure from large supermarket chains to sell their goods at a low price, many manufacturers have gone to lower production costs.
In addition, palm oil does not change the taste in any way, thanks to it the shelf life of packaged food increases and, finally, it has a very high flash point, which is why it is used when frying chips.
Of course, any product used by a person can be both beneficial and harmful if consumed in excess. This rule also applies to palm oil (both refined and deodorized), which in small quantities has a unique composition and beneficial properties for the body, but in large quantities it can cause irreparable harm. Whether or not to use products that contain this substance, everyone decides for himself, but we must not forget that the absence of the full composition on the package is not proof that the manufacturer did not hide palm oil in it.
