How is lecithin extracted from soy?
To make soy lecithin, soybean oil is extracted from the raw soybeans using a chemical solvent (usually hexane). then, the crude soy oil goes through a 'degumming' process, where in water is mixed thoroughly with the soy oil until the lecithinated becomes hydr and separates from the oil.
Soy lecithin powder suppliers, manufacturers, factory, customized, wholesale, buy, price, bulk, for sale. while rapeseed lecithin has relatively low nutritional value, so soybean lecithin is used in the food and feed industry.
The difference between soybean lecithin and egg yolk lecithin:
All kinds of oil seeds in nature contain phospholipids, but their content is not the same. among several common oil seeds, soybean and cottonseed are the most, followed by rapeseed. Soybean is the main one that can form industrial production. therefore, there is the term "soy lecithin" or "soy lecithin".
The general composition of soybean lecithin is: phosphatidylcholine PC (lecithin) 25-32%, phosphatidylethanolamine PE (cephalin) 15-22%, phosphatidylinositol PI (inositol phospholipid) about 15%, phosphatidyl glycerol PG (sphingomyelin) is about 16%, phosphatidic acid PA is about 4%, and other phospholipids are about 8%.
The main difference between egg yolk phospholipids and soybean phospholipids is that phosphatidylcholine is as high as 70%, and phosphatidylinositol is only 0.6%. does not contain: Phosphatidic acid, phosphatidylserine, N-acylphosphatidylethanolamine, phosphatidylglycerol.
Is soy protein extract and soy lecithin safe for dogs?
Soy lecithin helps support proper digestion of dietary fat and keep a dog's skin and coat healthy. soy lecithin can potentially lower cholesterol levels, especially when combined with niacin.
Dosage of a soy lecithin powder supplement for dogs: for small dogs,1-2 teaspoons of soya lecithin in their food. medium to large dogs can have 1-2 tablespoons. your vet before starting any supplement for your dog.
What chemical solvent is used to extract the soy lecithin?
Ethanol extraction: The principle is that lecithin is soluble in ethanol, and other phospholipids: cephalin and inositol phospholipids are insoluble in ethanol.
Layer-column analysis: the principle is that the adsorbents have different adsorption capacities for cephalin, inositol phospholipid, and lecithin.
Co2 supercritical extraction: the principle is the abnormal balance behavior and transfer performance of supercritical Co2 and lecithin. The different components are separated under varying temperature and pressure.
Membrane separation method: the principle is to use different lecithin, cephalin, and inositol phospholipids to form different molecular masses in different solvents for separation, such as using a phospholipid solution dissolved in a mixed solution of ethane-isopropanol to pass through a polypropylene semi-permeable membrane , can increase the lecithin content from 25% to 51%, and recover the solution flowing through the membrane and recover it, which can greatly improve the purity of lecithin. However, this method is not very mature and cannot distinguish components with similar molecular weights. currently limited to the lab.
The main dosage forms of lecithin for industrial use are: liquid, granule, and powder. the liquid concentration is about 60%, and the granule and powder can reach more than 95%.
