What is glycerol ester of rosin?

Glycerol ester of rosin, also known as glyceryl abietate, is a food additive used as an emulsifier and stabilizer in various products such as chewing gum, beverages, and candy. It is derived from rosin, which is a natural resin obtained from coniferous trees.

Glycerol ester of rosin is made by esterifying glycerol with rosin under high heat and pressure. The resulting product is a yellow to amber-colored viscous liquid that is soluble in ethanol and propylene glycol.

In food products, glycerol ester of rosin is used to help mix oils and fats with water-based ingredients, and it also helps to stabilize emulsions. It is commonly used in low-fat or reduced-calorie food products as a replacement for more calorie-dense emulsifiers or stabilizers.

Glycerol ester of rosin has been deemed safe for consumption by the Food and Drug Administration (FDA) and the Joint Expert Committee on Food Additives (JECFA), with no known adverse effects in normal use. However, some people may be allergic to rosin or related compounds and should avoid consuming products with glycerol ester of rosin.
