Applications:
The majority of lecithin (PC) content below 55% is used in foods, health foods and nutritious foods. The content of 60% and 80% is mostly used in cosmetics and pharmaceutical excipients. The content of more than 90% is mainly used in the pharmaceutical industry.
Phospholipids are phosphorus-containing lipids (lipids), including glycerophospholipids and sphingomyelins. Glycerophospholipids are widely distributed in animals, plants and Microorganismss.
Sphingophopholipids are generally found only in animals and micro-organisms, and are rarely found in plants. Commercial phospholipids mostly refer to glycerol phospholipids, such as plant phospholipids (soy phospholipids, rapeseed phospholipids, cottonseed phospholipids, etc.), egg yolk phospholipids, and their main components are phosphatidylcholine PC, phosphatidylethanolamine PE, and phosphatidylinositol Pl.
Lecithin Chemical name:
Phosphatidylcholine (PC). In accordance with the level of its purity, generally divided into PC50, PC60, PC70, PC80, PC90, PC95 and other product forms. The highest purity can be purified to 98%, because the higher the purity, the stronger the oxidation performance. Therefore, the lecithin purified to 98% needs to be hydrogenated and then stored. Unhydrolyzed lecithin is generally required in nitrogen-filled, sealed containers.
Pure lecithin is a colorless, odorless white solid at room temperature, and appears light yellow to brown due to different preparation or refining methods and storage conditions.
