Abstract
comparative study was conducted on the debittering effects of three debittering agents: flavored protease, activated carbon and ¦Â-cyclodextrin on collagen solution. The results show that the optimal conditions for flavor protease as a debittering agent are: enzyme dosage is 8 000 U, pH value = 6.5, temperature is 45 ¡æ, and time is 3.0 h; the optimal conditions for activated carbon as a debittering agent are: activated carbon dosage is 1 %, pH value = 7, temperature is 40 ¡æ, time is 0.5 h; the optimal conditions for ¦Â-cyclodextrin as a debittering agent: ¦Â-cyclodextrin dosage is 2.0%, pH value = 7, temperature is 35 ¡æ , the time is 1.0 h. By treating three kinds of debittering agents, flavor protease, activated carbon and ¦Â-cyclodextrin, the collagen
