Keywords
Grass Carp Scales, Collagen, Extraction, Physical And Chemical Properties
Abstract
Using grass carp scales as raw materials, acid-soluble collagen (ASC) and enzyme-soluble collagen (PSC) were extracted under conditions below the protein denaturation temperature, and their physical and chemical properties were systematically measured. Experimental results show that the thermal denaturation temperatures of ASC and PSC are 30-35¡ãC and 28-35¡ãC respectively; PSC is better than ASC in terms of solubility, emulsification performance and emulsion stability, while solution viscosity, water absorption performance, oil absorption performance, In terms of foamability and foam stability, ASC is significantly better than PSC
