摘　　要：谷物是我国重要粮食作物,淀粉作为谷物的主要成分,不仅提供膳食能量,还与食品品质紧密相关。然而,天然淀粉易老化、抗剪切能力差,糊化后的淀粉还存在析水、热不稳定等问题,限制了淀粉的应用范围。利用非淀粉多糖对淀粉进行改性处理是一种绿色环保的改良方法。多糖水解产物也表现出提升淀粉加工特性的应用潜力,对于食品加工具有重要意义。本文概述多糖添加对淀粉糊化、流变、质构和体外消化特性的影响,以及多糖水解产物对谷物淀粉品质影响的研究进展,以期为谷物淀粉基食品物性改善提供理论参考。Cereals are important food crops in China.As the main nutritional component of cereals,starch is closely related to the quality of starch-based foods.However,natural starch has shortcomings such as easy aging and poor shear resistance,and the gelatinized starch also has problems such as water separation,easy aging,and thermal instability,limiting its application range.Introducing hydrophilic colloids such as non-starch polysaccharides is a green and environmentally friendly starch modification method.Moreover,the hydrolysates of polysaccharides also exhibit potential applications to improve the processing characteristics of starch,which is of great significance for food processing.This article summarizes the effects and mechanisms of polysaccharides on starch gelatinization,rheology,texture,and in vitro digestion properties,as well as the research progress in the effects of polysaccharide hydrolysates on the quality of cereal starch.It is expected that this work could provide theoretical reference for improving the physical properties of cereal starch-based foods.
