Sugar Alcohols
- Potentially Harmful
Definition
Glycerin is a sugar alcohol: a hybrid of sugar and alcohol molecules used as a low calorie substitute for sugar. There are three types of glycerin, animal glycerin made from animal fats like tallow, vegetable glycerin made from vegetable fats such as soybean, coconut or palm oils, and synthetic glycerin made from petroleum. Usually the product is glycerine and the ingredient is glycol: for example glycerin syrup is made mostly of glycol. Vegetable Glycerins are made by heating triglyceride-rich fats under pressure or together with a strong alkali, such as lye. In addition to being a food additive, glycerins are also commonly used in pharmaceutical drugs and cosmetics.
