Vegetable glycerin (also known as vegetable glycerol or glycerine) is an organic substance extracted from vegetable oils (mostly palm and coconut oils). The compound is clear, colorless, sweet and has an oily consistency. Its chemical structure reveals atoms of hydrogen, three atoms of carbon and three groups of hydroxide which create hydrogen bounds with water thus leading to the thick, oily formula.
Vegetable Glycerin Properties
Vegetable glycerin is a carbohydrate. It has a sweet taste however it does not raise blood sugar, which makes it great as a sugar replacement in low carb diets. Vegetable glycerin has a low freezing point, it is soluble in water and alcohol and can substitute alcohol in different herbal tinctures and concoctions.
Vegetable Glycerin’s Uses in Food Industry
Although a carbohydrate, vegetable glycerin is metabolized differently than other similar substances. Unlike sugar and sugar-based sweeteners, this substance can be successfully employed in low carb diets as sweetener, without raising blood sugar levels. Its low glycemic index and its high sweetening power advocated the benefits of this substance and convinced American Dietetic Association to include it on the “safe” list.
Vegetable glycerin (aka glycerol or glycerine) increases the shelf life of different food products; therefore it is largely used as a natural preservative. The substance acts as a humectant, keeping cookies fresh and the fillings soft for a long time. In liquors, vegetable glycerin is used as thickening agent. As a food additive, it is labeled as E422. The substance used in food industry is 99.7% pure, the remaining 0.3% being water.
Uses of Vegetable Glycerin in Cosmetic Industry
