How and from what products is palm oil produced?
Public opinion today has developed in such a way that palm oil is considered one of the most harmful vegetable oils that are harmful to human health. Products containing this ingredient are considered to be second-rate and of poor quality. Nevertheless, such oil is used for the production of various finished products and semi-finished products, it is used in the cosmetic and technical industries.
According to rough estimates, every second product on the shelves of any supermarket contains palm oil. To find out if it is really as dangerous as they say about it, you can only find out its composition and production technology.
Basic properties and composition
Palm oil is a vegetable fat obtained from the soft fruit of the palm tree. This plant is called "oilseed" and can be found in some Asian countries, in Africa and on the islands located in the Indian Ocean. This is due to the fact that the ripening of the fruits of such a palm tree requires high humidity and temperatures of +24 degrees and above.
Such oil looks like a transparent liquid without taste, in its consistency it is slightly thicker than ordinary water and has a pleasant sweetish aroma. At low temperatures, it solidifies and turns into a white paste. To return this paste to a liquid state, it must be melted in a water bath or in a microwave oven.
Vegetable fat extracted from palm fruits is often used in cooking as a preservative, as it can be stored for about 3-4 months without losing its properties. Even at room temperature, this tasteless liquid can be stored for several days and does not deteriorate. In addition, this oil is so popular because of its low price, which is significantly lower than the price of other oils. When palm oil is made, food additives called stearin and olein are obtained, which in turn are used in the production of margarines.
The calorie content of palm oil is quite high - about 900 kcal per 100 g, and all of them are vegetable fats, and proteins and carbohydrates are simply absent in this product. This product cannot be called dietary, but no one consumes vegetable fats in their pure form. Depending on its content in the final product, the calorie content of the latter can be much lower. In addition to vegetable fats, this oil contains several useful fatty acids, vitamin E and A. Unfortunately, palm oil contains only small amounts of phosphorus among useful trace elements.
Ingredients
The composition of the oil palm fruit also determines the final composition of the resulting product. If vitamins and minerals are widely considered to be useful substances for the human body, then disputes about saturated fatty acids still do not subside. In fact, all the ingredients that make up vegetable fat do not in themselves cause any harm to a person.
- Vitamin E (alpha tocopherol) necessary to protect the body from premature wear and aging of cells. It is useful for the skin of the face and body, allows the hair to retain its density and natural shine.In addition, vitamins of group E favorably affect the work of the hormonal system.
- Vitamin A (retinol) enters the body from carotene. It is necessary for the normal functioning of human immunity, proper metabolism, as well as the health of teeth and nails.
- Phosphorus important for cell regeneration, especially in muscles. However, even 100 g of natural palm oil in its pure form can hardly cover the daily human need for this trace element, so it is better to get phosphorus from other products.
- Lauric acid acts as a disinfectant and disinfectant, therefore it is often used in the creation of cosmetic products. It protects the human body from viruses and pathogenic bacteria.
- Palmitoleic acid It is considered one of the most beneficial for the human body, as it is necessary for the growth and regeneration of nerve endings. It lowers blood cholesterol levels and lowers high blood pressure.
- Myristic acid practically useless for humans, since it is not absorbed in the intestines and leaves with secretions. However, it does not cause any harm to a person who consumes palm oil.
Thus, among the beneficial qualities of the oil, some cleansing of the body, care for vision and external health can be noted. Such vegetable fat satisfies hunger well, improves brain function and gives strength, which is why it is often used when the body is severely depleted. If a person does not have an individual intolerance to a palm product, then infrequent use of it in food can in no way harm his health.
With excessive consumption of foods containing a large amount of this vegetable fat in their composition, problems with the cardiovascular system, the work of the digestive tract, and even obesity can occur.
Production technology
In order to obtain vegetable fat from palm fruits, it is not enough just to collect ripe fruits. Palm oil is made by exposing the juicy pulp to high temperatures. To do this, the fruits are placed in large metal vats and boiled for a short time. The resulting fat rises where it is collected for further refining. This purified (refined) oil is produced by rotating the liquid in a centrifuge.
Due to the high speed, the product is stratified into fat and water with impurities, which are removed from the finished product. In addition, palm oil can be made by hand and gently refined. In this case, all harmful impurities will be removed, and useful components will remain in greater quantities.
Kinds
Depending on the method of purification and applications, vegetable fat obtained from palm fruits, can be divided into three main types.
- Red oil. It has a pleasant aroma and sweet taste. This product is made entirely by hand. It has the highest price of all three types. Most often, it can be purchased in a solid pasty form, and during heat treatment, such a paste turns into a liquid.
- Ordinary palm oil. In the food industry, this type of oil is most often used. It has been refined in a centrifuge, cleaned of all harmful substances, but, unfortunately, contains practically no useful acids and vitamins.This ingredient is purchased in the form of a clear liquid, poured into large containers, and is most often used in the production of cheap fermented milk products, various desserts and snacks.
- Technical palm fat. Such fat is several times cheaper than regular oil and is not used for food. Due to the low degree of purification, it contains too many oxidized fats that are harmful to the human body. It is used in cosmetology and industrial production, but some unscrupulous manufacturers, in order to save money, can add it to milk, bread and other products. Most of the articles describing the high risk of palm oil consumption are written about such products.
Applications
As mentioned above, the main direction which uses vegetable palm oil - this is cooking.
- Bakery production, various sweets, sweets, chocolate, cakes and cookies - all this contains palm oil. It extends the shelf life of products and allows them to retain their properties at room temperature.
- Milk and dairy products made with palm oil. To achieve a certain fat content of milk, which was previously defatted during separation, it is vegetable fat that is used. This allows for longer shelf life of perishable yoghurts and cream, ice cream and sour cream.
- Production of cosmetic products. Vegetable fat is added to various creams and lipsticks; soaps and shower gels are made on its basis. Such a product, containing vitamins A and E, as well as lauric acid, fights skin impurities well, is good for hair and teeth, and serves as an anti-aging agent.
Oil from the fruit of a palm tree growing in Africa and Asia is used today almost all over the world. By itself, such oil, if it is prepared and refined according to the correct technology, does not pose any risks to humans. Nevertheless, it is quite high in calories, so the use of products that contain it in their composition should be controlled.
