Definition and Usage Areas of Lecithin
Lecithin, also known as phosphatidyl, is essentially a phospholipid, and phospholipid is the substance that generally forms the building blocks of cells, protecting them and keeping them healthy. At the same time, they prevent the hardening of the cell membrane and protect the cells against the formation of oxidation. They also act as the protective membrane that protects and surrounds the brain in the human body.
Since lecithin, which is generally used in the pharmaceutical industry, is an extremely purified mixture, it is said that it is not allergic in any case. Only those who are allergic to soybeans may need to be careful when using lecithin, which is also produced from soybeans. In this case, it should be known that lecithin produced from soybean can cause allergies in these people as soybean causes. Plants or foods from which lecithin will be obtained generally have a high oil content. Because of the lecithin in these foods with high fat content, direct use will not work. At the same time, it should be known that these plants with high oil content can have negative effects against cholesterol.
For lecithins obtained from soybeans, when we look closely at soybean, we see that soybean, which is a food that provides all amino acids in sufficient proportion, is a complete protein source, unlike meat types, because it contains several amino acids together. In cases where they are combined with other types of protein, they are digested more easily by our digestive system and in this way, they can reach protein values far above their protein values.
- It is an important raw material in the food industry and especially in chocolate production. It is often used as an emulsifier in food.
- It is a raw material with surface active feature. Because of this feature, it is used as a wetting and dispersing agent in the production of pharmaceuticals and margarine.
- In agriculture, it is used both as a wetting agent, dispersant and emulsifier when producing insecticides, fungicides, herbicides or acaricide drugs.
- In the pharmaceutical industry, it acts as a wetting agent, stabilizing agent and choline enrichment carrier, aids emulsifications and encapsulation, and forms a good dispersing agent. It can be used in the manufacture of intravenous oil infusions and for therapeutic use.
- It enriches fat and protein in animal feeds and improves pellet formation.
- It forms protective coatings for dyeing and ink printing in the paint industry, has antioxidant properties, helps as a rust inhibitor, is a color enhancing agent, catalyst, conditioning aid modifier and dispersant aid; emulsifier and wetting agent, a good stabilizing and suspending agent, helps to maintain a homogeneous mixture of pigments, helps disperse metal oxide pigments, based paints and fast latex based paints.
- Lecithin can also be used as a release agent for plastics, a degreasing additive in motor oils, an antifoam agent in gasoline, and an emulsifier, spreading agent and antioxidant in textile, rubber and other industries.
