Starch is an important source of energy for the human body and a common food ingredient. However,starch-based foods are prone to retrogradation, which leads to a hardened texture, poor taste and quality deterioration.Retrogradation is one of the most important reasons for the deterioration of the quality of starch-based foods.Delaying starch retrogradation can maintain the taste and quality of starch-based foods and extend their shelf life. The article introduced the mechanism of starch retrogradation and the main factors influencing it. It analyzed and compared measures such as physical methods, natural exogenous additives and enzymatic methods to delay starch retrogradation. In addition, optimized the processing technology of starch-based foods, packaging materials and storage conditions were also effective measures to delay retrogradation. The purpose of this article aims to summarize the latest progress in delaying retrogradation of starch-based foods, and provide scientific basis and technical support for starch food processing.
