湿热处理技术对淀粉理化特性影响的研究进展

摘要

Heat-moisture treatment (HMT)is one of the most popular approaches in the field of starch modification. HMT,referred as environmental-friendly approach,is a physical modification to produce modified starch products which do not remain any chemical residues. HMT can modify starch,including modality,crystalline,thermal properties and starch gel properties. HMT increases the amount of slowly digestible starch and resistant starch. The impact of HMT on starch physiochemical properties and nutri-tional properties was summarized,as well as the application and development in food industry.%随着人们对变性淀粉需求量的增加，湿热处理技术成为了变性淀粉研究的热点之一。湿热处理是用于生产变性淀粉的一种物理手段，不带来任何化学试剂残留，属于环境友好型新技术。湿热处理可以改变淀粉的形态、结晶性、热学性质、淀粉胶性质，增加缓慢消化淀粉和抗性淀粉含量。为了促进湿热处理技术的研究、应用以及使人们对该技术有一个全面而清晰的认识，综述了湿热处理对淀粉理化性质和功能特性的影响，以及湿热处理淀粉在工业中的应用与发展前景。
