摘　　要：冻融处理是常用的物理改性方法,在影响淀粉冻融特性的因素中,冻融循环次数是最主要的因素之一。研究发现冻融处理可以提高淀粉的吸油率,导致淀粉晶体结构发生转变,使结晶度增加,而这些变化的形态因素与冻融循环次数呈显著相关。本文总结冻融循环次数对淀粉结构特性和理化性质的影响,通过对冻融循环中淀粉结构和性质的变化为进一步研究改性淀粉提供理论依据。Freeze-thaw treatment is a commonly used physical modification method,and the number of freeze-thaw cycles is one of the most important factors affecting the freeze-thaw characteristics of starch.Many studies have found that freeze-thaw treatment can improve the oil absorption rate of starch,resulting in the transforma-tion of starch crystal structure and the increase in crystallinity.In addition,the morphological factors of these changes are related to the number of freeze-thaw cycles.In this paper,the effect of the number of freeze-thaw cycles on the structural properties and physicochemical properties of starch was summarized,and the changes in the structure and properties of starch during freeze-thaw cycles could provide a theoretical basis for further research on modified starch.
