Lecithin is used for applications in human food, animal feed, pharmaceuticals, paints, and other industrial applications. Applications include: In the pharmaceutical industry , it acts as a wetting agent, stabilizing agent and a choline enrichment carrier, helps in emulsification and encapsulation, and is a good dispersing agent.
Soy lecithin is a common food additive that’s often used to improve the consistency and quality of packaged foods.. Take salad dressing, for example.As an additive, soy lecithin emulsifies ...
Egg lecithin is usually extracted chemically using ethanol, acetone, petroleum ether but not benzene or hexane due to restrictions on residual solvents by the pharmaceutical regulations. [2] It is an emulsifier, especially for parenteral use since it does not need to be metabolized.
Dipalmitoylphosphatidylcholine (lecithin) is a major component of the pulmonary surfactant, and is often used in the lecithin–sphingomyelin ratio to calculate fetal lung maturity. While phosphatidylcholines are found in all plant and animal cells, they are absent in the membranes of most bacteria, [ 1 ] including Escherichia coli . [ 2 ]
Phospholipids are one of the components of lecithin, which is found in egg yolks, as well as being extracted from soybeans, and is used as a food additive in many products and can be purchased as a dietary supplement. Lysolecithins are typically used for water–oil emulsions like margarine, due to their higher HLB ratio. [citation needed]
The most common example of a phytosome is Lecithin. [1] Phytosomes are claimed to enhance the absorption of "conventional herbal extracts" or isolated active principles, both topically [2] and orally. [3]
Lecithin, monoglycerides, diglycerides, and DATEM are considered emulsifiers. They disperse fat more evenly throughout the dough, helping it to trap more of the CO 2 produced by yeast. [29] Lecithin added at a rate of 0.25-to-0.6% of the flour weight acts as a dough conditioner. [30] Based on total weight, egg yolk contains about 9% lecithin. [31]
Hydroxylated lecithin is chemically modified lecithin. It is made by treating lecithin with hydrogen peroxide and an organic acid such as acetic or lactic acid. [1] In the process, some of the organic acid becomes peroxy acid. The peroxy acid reacts with olefins in the fatty acid side chains creating intermediate epoxides.
