Optimization of preparation for tilapia scale collagen peptide zinc chelate

In order to obtain the best preparation process for tilapia scales collagen peptide zinc chelate,response surface methodology was used to optimize the preparation process,and a mathematical model of peptide zinc chelate yield with the relation of pH,peptide zinc mass ratio,time and temperature was established.The optimal preparation process was as follows: pH 5.0,peptide zinc mass ratio 2.5:1,time 35 min and temperature 54℃.Under the above condition,the predicted value of the peptide zinc chelate yield was 92.79%,and the experimental value was 91.96%,which was no significant difference between the experimental and predicted values.The mathematical model obtained in this experiment will provide a basis for further research of fish scales processing.
