兔皮胶原蛋白的加工特性
Processing Characteristics of Rabbit Skin Collagen
摘要
Abstract
In the present study,rabbit skin collagen was analyzed for its processing characteristics.The results showed that the water absorption capacity of rabbit skin collagen was 14.89 mL/g.The collagen had a high solubility in acidic environment,especially at pH 3,and the solubility was decreased to 50％ in alkaline environment.Ionic strength had a significant effect on the solubility of the collagen.At NaCl concentrations in the range of 0-2 g/100 mL,the solubility of the collagen remained relatively stable,whereas it decreased sharply with NaCl concentration up to 4 g/100 mL,and then did not change significantly at NaCl concentrations higher than 4 g/100 mL.The emulsifying capacity of the skin collagen increased with its concentration up to 1 g/100 mL,and then it began to decline with further increasing its concentration,but the opposite trend was observed for emulsion stability.Both emulsifying properties decreased with increasing pH from 3 to 6 and then gradually increased to a plateau with further increasing pH to 9.Emulsifying capacity presented a decreasing trend after an initial increase with NaCl concentration up to 7.02 g/100 mL,while emulsion stability remained stable after an initial increase.Both emulsifying capacity and emulsion stability were good at a NaCl concentration of 5.85 g/100 mL.关键词
