'''Glycerol ester of wood rosin (or gum rosin)''', also known as '''glyceryl abietate''' or '''ester gum''', is an oil-soluble [[food additive]] ([[E number]] E445). The food-grade material is used in foods, beverages, and cosmetics to keep oils in [[suspension (chemistry)|suspension]] in water,<ref>[http://www.inchem.org/documents/jecfa/jecmono/v35je05.htm WHO Food Additives Series 35: 836. Glycerol ester of wood rosin]</ref> and its name may be shortened in the ingredient list as '''glycerol ester of rosin'''. It is also used as an ingredient in the production of chewing gum and ice cream.
To make the glycerol ester of wood rosin, refined [[Rosin#Production|wood rosin]] is reacted with [[Glycerol|glycerin]] to produce the glycerol [[ester]].
Glycerol ester of wood rosin is an alternative to [[brominated vegetable oil]] in citrus oil-flavored soft drinks. In some cases, both ingredients are used together.
