Sucrose acetoisobutyrate (SAIB) is an emulsifier and has E number E444. In the United States, SAIB is categorized as generally recognized as safe (GRAS) as a food additive in cocktail mixers, beer, malt beverages, or wine coolers and is a potential replacement for brominated vegetable oil.

SAIB can be prepared by esterification of sucrose with acetic and isobutyric anhydrides.
