Glycerin, also known as glycerol, — is a clear, sweet, viscous liquid obtained from plant or animal fats, as well as synthetically.
It has long been used in the food, cosmetic, and pharmaceutical industries, but among chefs and advocates of low-carb diets, glycerin has become particularly popular as a universal moisturizer, texture stabilizer, and mild sweetener.
History and Origin
Glycerin was first isolated in the late 18th century during the saponification of fats. With the development of soap production and the subsequent emergence of oil hydrolysis, glycerin became available in large volumes and began to be actively used in cooking and food storage technologies.
Today, the majority of food-grade glycerin is produced from vegetable oils — coconut, palm, and soybean.
