PREPARATION METHOD FOR STARCH-LIPID-PROTEIN COMPLEX, AND APPLICATION THEREOF

摘要

A preparation method for a starch-lipid-protein complex, and an application thereof. The preparation of the complex comprises the following steps: (1) adding a water-soluble protein in a starch and lipid system, heating, by means of controlling a water temperature, a mixture system until starch is gelatinized, and then performing cooling to obtain a complex sample; and (2) grinding the complex into powder after freeze-drying, and storing same. The complex can be subjected to rehydration to obtain a fat mimic; the fat mimic has a physical property similar to cream, is simple in preparation process, high in heat stability, low in glycemic index, has a potential function of regulating intestinal health of a human body, and can be applied to ice cream for replacing part of cream, thereby reducing the fat content and reducing the damage to human health due to excessive calories thereof. Moreover, a sensory evaluation result shows that the addition of the fat mimic can effectively compensate for the loss of taste and flavor of the ice cream caused by the reduction of fat content. The complex may be further used as a food ingredient for food processing.
