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 …

2015年2月1日 · Starch acetylation is a chemical modification by which part of the hydroxyl groups of glucose monomers is converted into acetyl group, altering the molecular structure of the starch. Acetylated starches are produced with acetic anhydride with an alkaline agent, such as sodium hydroxide, as catalyst ( Bello-Pérez, Agama-Acevedo, Zamudio-Flores ...

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.

2021年9月1日 · Starch isolated from amaranth was modified by heat moisture treatment at different temperatures (85, 100 and 120 °C), oxidation and acetylation. Native and treated starches were assessed for physicochemical, pasting, gel textural, structural, thermal and morphological properties.

Acetylated starch with low degree of substitution is used in the food industry to control and adjust the rheological behavior of pastes [166], while succinylated starches reinforce the swelling...

2023年9月30日 · This review aimed to summarize current methods for starch acetylation and discuss the structure and functionalities of acetylated starch. Innovative techniques, such as milling, microwave, pulsed electric fields, ultrasonic, and extrusion, could be employed for environmental-friendly synthesis of acetylated starch.

Starch acetylation is a chemical modification by which part of the hydroxyl groups of glucose monomers is converted into acetyl group, altering the molecular structure of the starch. Acetylated starches are produced with acetic anhydride with an alkaline agent, such as sodium hydroxide, as catalyst (Bello-Pérez,

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8月1日 · Acetylation led to the degradation of starch structures and weakening of the interactions between starch molecules, resulting in the disorganization of starch multi-scale ordered structure.

2015年2月1日 · Acetylation and oxidation are chemical modifications which alter the properties of starch. The degree of modification of acetylated and oxidized starches is dependent on the catalyst and active chlorine concentrations, respectively.
