How much do you know about phospholipids in edible oil?

Speaking of edible oil, how much do you know about the phospholipids in edible oil?

  • 1. What is phospholipid? Phospholipids (PL) is a general term for phosphate-containing lipids, which are widely present in the native materials and biofilms of animal and plant cells, and play an important role in regulating the biological activity of biofilms and the normal metabolism of the body.
    However, Phospholipid is not alone, its family is huge.Phospholipids are classified into glycerol phosphate and sphingolipids according to their composition. Among them, glycerol phosphate is a derivative of phosphatidic acid (PA), the common ones are lecithin (phosphatidylcholine, PC), cephalin (phosphatidylethanolamine, PE), serine phospholipid (phosphatidyl acid PS), inositol Phospholipids (phosphatidylinositol, PI), phosphatidylglycerol, etc.According to the different main bodies of phospholipids, it can be divided into animal phospholipids and plant phospholipids. The seeds of oil crops mainly contain plant phospholipids. Phospholipids are an important oil companion organism produced in the process of oil production.
  • 2. How much do you know about the history of phospholipids? Phospholipids were first found in the human brain and later separated from egg yolks. In 1961, Japan approved the use of soybean lecithin. Since the 1970s, phospholipid health products have been used in European and American countries. As early as the 1950s, China began to research and develop phospholipids, but due to the limitations of technology and equipment, it did not get a strong development. It was not until the 1990s that the industrial production of phospholipids was realized.
  • 3. What is the application of phospholipids in the food industry? Phospholipids have the functions of dispersibility, softness, and oxidation resistance. They are also excellent emulsifiers, stabilizers and dispersants. They are widely used as food additives in various processed foods, such as margarine, chocolate, bread, steamed bread, snacks, vermicelli , Milk powder, etc.
  • 4. Should phospholipids be removed from edible oil? Vegetable oil naturally contains a lot of phospholipids. With the continuous development and progress of the food industry, the attitude of the oil industry to phospholipids has also changed. In the past, phospholipids were removed as much as possible, but now they can be properly retained without affecting product quality and safety.
