固形物与甘油含量对胶原团及胶原蛋白肠衣膜的影响

hispaper research the effects of collagen content and glycerol content on the mechanical properties of collagen casingfilms, research the relativity of the rheological properties of collagenpastes and the properties of collagen casingfilm, supply the new study ideas and the content of solids and glycerol added in casing for the casing industry. Research indicated that the content of collagen pastes has great influence on the performance of casing casing film, the suitable solid content made collagen casingfilm own better mechanical properties. With the increase content of glycerol, tensile strength decreased, the elongation increased and swelling degree also decreased. With the increase of collagen pastes gel strength, tensile strength of collagen film will increase, but it is not linear. The final screening formula was: 5% solid content, 20% glycerol, the mechanical properties of collagen casings were best at this formula.
