Acetylated starch, E1420 in the E number scheme of food additives, is a modified starch. These are not absorbed intact by the gut, but are significantly hydrolysed by intestinal enzymes and then fermented by intestinal microbiota .

2023年9月30日 · This review focused on the development of acetylated starch with emphasis on the novel synthesis technologies, the changes in starch multi-scale structures, their effects on starch versatile functionalities, and potential applications of …

Acetylated oxidized starch is obtained in two stages: oxidation of starch with sodium hypochlorite at low temperature (21–38 °C) in an alkaline environment, followed by esterification with acetic anhydride under slightly alkaline conditions.

Modification by acetylation has been widely used to improve the quality and stability of starch. This review describes the effects of acetylation modification and its dual modifications on the physicochemical properties of starch/flour and their applications.

Experimental analyses were performed to investigate the effect of acetylation on a range of starch properties, including granule morphology, solubility, swelling power, paste clarity, syneresis and freeze-thaw stability, and compare them with those of the native corn starch.

2023年7月9日 · Modification by acetylation has been widely used to improve the quality and stability of starch. This review describes the effects of acetylation modification and its dual modifications on the physicochemical properties of starch/flour and their applications.
