Acetylated oxidized starch

Description:Acetylated oxidized starch is a food and beverage ingredient used as a thickener.It is a chemically modified root or grain starch. It is produced by oxidation of a slurry of starch granules in alkaline hypochlorite at low temperature (21–38 °C). The alkaline medium is neutralized with sodium bisulfite, and the resulting organic salts are removed by washing with water. The oxidized starch is then esterified with acetic anhydride under mildly alkaline conditions.
