Analysis and prospect on rapidly evaluated system for gelatinization of collagen

Gelatin yield and gel strength are the main evaluation indicators of the gelatinization degree of collagen,but the value measured must complete gelatinization of collagen and hot water extraction two process.Therefore,it can greatly save research time and costs that directly evaluate the gelatinization degree of collagen with the typical structure of the collagen. According to variation of microstructure of collagen treated by traditional acid- alkali,enzyme and ultra- high pressure,relationship between typical structures of gelatinized collagen and main evaluation indicators were discussed. Meanwhile,the evaluated methods based on the typical microstructure for gelatinization of collagen were analyzed and predicted.
