is an ester of acetic acid and isobutyric acid with sucrose and is a mixture of sucrose esters of various structures. Colorless to light yellow viscous liquid. No special odor, insoluble in water, soluble in ethanol, esters, acetone and other organic solvents. The boiling point is about 288 ℃, and the refractive index is 1. 4540.
sucrose is firstly acetylated with two molecules of acetic acid, and then the product is prepared by transesterification with methyl isobutyrate and refining.
mainly used as food emulsifier, stabilizer and turbidity agent. It can also be used as a pesticide, the synthesis of pharmaceutical intermediates, preparation of isobutyrate plasticizers and flavors and fragrances.

use | as W/O food emulsifier, China stipulates that it can be used for emulsifying essence, with a maximum usage of 70 g/kg, equivalent to 0.14 g/kg in carbonated beverage. Stabilizer; Relative density adjuster; Turbidity agent for alcohol-free beverages. Used as a food additive, mainly used to prepare emulsified flavors; it can also be used as a plasticizer for film, paint, ink, etc. |
production method | is obtained by distillation after esterification of food grade sucrose with acetic anhydride and isobutyric anhydride. It is a mixture of esters in all possible binding forms, in which the ratio of acetate to butyrate is about 2:6. The product is obtained by the esterification reaction of sucrose with acetic anhydride and isobutyric anhydride after distillation. |
