Abstract
The present disclosure discloses a processing method for intelligent hydrogel from nano-scale starch particles, and belongs to the technical field of nutritional health food. The present disclosure uses dendritic water-soluble starch particles as a skeleton and utilizes a transglycosidation and chain extension-glycan entanglement reaction of glycosyltransferase to obtain an intelligent hydrogel having a spatial reticular structure. The product provided by the present disclosure is an intelligent starch-based hydrogel which has good rehydration capability, biocompatibility, strong gel strength, enzymatic response irreversibility, pH response reversibility, can carry multiple nutritional factors. The hydrogel provided by the present disclosure can protect and control the release of food functional factors, and can be applied to food, biological drug loading, functional materials and the like.
