Sucrose Acetate Isobutyrate is a part of sugar which is a mixture of esterified products commercially produced by controlled esterification of sucrose with acetic acid anhydride and isobutyric anhydride. It’s primary function in food is to be used as an emulsifier in flavored beverages to stabilize the emulsions of flavoring oils and prevent its separation with water. In addition, this substance can be used as a weighting agent to suspend oil-based ingredients in energy drinks or flavored water. The physical appearance of Sucrose Acetate Isobutyrate is a pale straw-colored viscous liquid and insoluble in water.
The manufacturing process starts from reacting diacetyl oxide, isobutyric anhydrate, and organic bases in a reactor with a continuous stirring at 1000C. The mixture was then decolorized by adding discoloring agent, such as acidic white earth and diatomite. The next step was to wash away the remaining acid by under pressure distillation. The last step was to dehydrate the solution at 50 – 1200C to obtain the viscous liquid product.
Food and Beverage Industry
Sucrose Acetate Isobutyrate (SAIB) is a pure liquid food preservative that is processed as an emulsifier. It mixes water and fat. SAIB helps suspend and distribute flavor oils in a drink. It is used predominantly in citrus beverages, especially energy drinks to prevent the separation of essential citrus oils.
