Modification of Collagen Hydrolysate by EDAC.

Keyong Tang, Cao Jian, Jintao Wang

Abstract

The work in this paper describes the modification of collagen hydrolysate with 1-ethyl-3- (3-dimethyl aminopropyl)-carbodiimide (EDAC). The effects of factors that may affect the cross-linking reactions in the process of modification such as EDAC level, reaction temperature, reaction time, and pH were studied. The optimal modification conditions were obtained to give modified products with the best emulsification and emulsion stability. Changes in molecular weight, emulsification capacity, emulsification stability, water absorption and oil absorption of the collagen hydrolysate before and after modification were studied and compared.
