Sucrose acetate isobutyrate

Emulsifier: Citrus-flavored beverages, including "energy," "sport," and "electrolyte" drinks, as well as such alcoholic beverages as wine coolers, malt beverage coolers, and premixed cocktail products.
Sucrose acetate isobutyrate (SAIB), like brominated vegetable oil, is used primarily in citrus-flavored drinks to keep the flavor oils in suspension, giving them a cloudy appearance. In January 2013 it was announced as a replacement for brominated vegetable oil (BVO) in Gatorade, following widespread consumer protest over BVO.

FDA has approved its use in non-alcoholic and alcoholic beverages up to 300 ppm. SAIB has been subjected to short- and long-term studies in laboratory animals and people, at high doses, with little, if any, evidence of harm. It is also approved for use in Europe.
