Abstract: | [Objective] To optimize technique of extracting fish scale collagen with enzymatic method and fully utilize fish products processing by-products. [ Method] With tilapia fish scales as raw material, papain enzymolysis method was used to optimize the extracting technique, the obtained collagen properties were analyzed. [ Result] The results showed that, the optimal conditions were enzyme dosage 2.5%0, 5 h under 50 ℃. [ Conclusion ] The collagen has good water absorption, retention, foaming stability with fine application prospect. |
