Abstract
Using rabbit skin collagen as raw material, its processing characteristics were systematically studied. The results show that rabbit skin collagen has strong water absorption, reaching 14.89 mL/g; it has high solubility in acidic environment, with the highest solubility when the pH value is 3, and the solubility drops to the lowest in alkaline environment. About 50%; the ion mass concentration has a significant impact on the solubility of collagen, which remains relatively stable when the NaCl mass concentration is 0 to 2 g/100 mL, and increases from 2 g/100 mL to 4 g/100 mL process, and when the NaCl mass concentration is greater than 4 g/100 mL, the change in collagen solubility is no longer obvious; when the mass concentration of collagen is less than 1 g/100 mL, the emulsification of rabbit skin collagen increases with the collagen The increase in protein mass concentration gradually increases, but when the mass concentration exceeds 1 g/100 mL, the emulsification decreases, and the emulsification stability shows an opposite trend to the emulsification with the change of collagen mass concentration; the pH of low mass concentration collagen solution is During the process of pH 3 to 6, both emulsification and emulsification stability showed a downward trend. Then, at pH 6 to 9, the emulsification and emulsification stability slowly increased and then remained stable; the ion mass concentration ranged from 0.00 to 7.02 g/100 mL. As the ion mass concentration increases, the emulsification property shows a trend of first increasing and then decreasing, while the emulsification stability shows a trend of first increasing and then remaining stable. When the ion mass concentration is 5.85 g/100 mL, the emulsification property of collagen is consistent with that of collagen. Good emulsification stability
