中文摘要: 淀粉老化是一个及其复杂的过程,通过淀粉颗粒结构分析,淀粉在过量水和高温条件下的老化过程以及不同物质对淀粉老化的影响等方面来探讨老化的机理。淀粉颗粒是由不同比例的直链淀粉和支链淀粉组成,其中支链淀粉所占比例更大一些;淀粉老化是淀粉颗粒天然序列重组后形成的直链淀粉和直链淀粉分散体;几丁质纳米棒状颗粒、带电荷氨基酸、盐、低聚花青素、二糖等物质能抑制淀粉的老化,但也存在一些争议,需要进一步研究。对淀粉内部结构的阐述可以更确切的了解淀粉老化机制,也为提高食品质量提供研究方向。

Abstract:The retrogradation of starch has different levels of complexity;the approach consists of the architecture of the starch granule,a discussion of disorganization in excess water and high temperature and followed by effect of different additives on the retrogradation of starch.The granules are composed of different proportions of amylose and amylopectin,with the latter in larger quantity;the terms retrogradation is excess water aqueous dispersions of amylose or amylopectin but also after a disorganization of the native order of starch granules;the inhibition of starch retrogradation with chitin nano-whiskers,charge carrying amino acids,salt,oligomeric procyanidins,disaccharides are studied,however,it is still controversial,and further research was required.The more accurate location and knowledge of the states by microstructure studies and also their characteristics along staling could be interesting to study to gather more information,and to supply a research direction to enhance food quality.
