Abstract:

Hydrogel is a polymer with a three-dimensional network structure, and is widely used in food, daily necessities and high technology fields. This article introduced the applications of natural hydrogels in food by using the examples of delicacy from Xi'an. On one hand, the chemistry for the preparation of these foods was well introduced, especially the potential health hazards and identification methods of borax, industrial gelatin and alum in hydrogel food were also introduced. On the other hand, the properties and advanced applications of hydrogels are also included.

Key words: Hydrogel, Delicacy, Food safety
