Chemical properties

Colorless or light yellow transparent paste, odorless, slightly salty. Solidified at room temperature, semi-fluid at 30-40℃, liquid above 40℃, relative density 25251.141-1.15, boiling at 288℃, refractive index nD401.4492-1.4504. Soluble in ethanol, ketones and ester solvents, slightly soluble in water (25℃, 0.1%). Oral LD50 for mice＞21.5g/kg, Adl0～10mg/kg (tentative, FA/WH0, 1996).

Uses

As a W/O type food emulsifier, my country stipulates that it can be used for emulsifying flavors, with a maximum usage of 70g/kg, equivalent to 0.14g/kg in carbonated beverages.

Stabilizer; relative density adjuster; turbidity agent for non-alcoholic beverages.

Used as food additives, mainly used to prepare emulsified flavors; can also be used as a plasticizer in film, paint, ink, etc.

Production method

It is obtained by esterifying food-grade sucrose with acetic anhydride and isobutyric anhydride and then distilling it. It is a mixture of all possible esters, in which the ratio of acetate to butyrate is about 2:6.

The product is obtained by esterification of sucrose with acetic anhydride and isobutyric anhydride and distillation.
