英文摘要:

      Objective To explore the process parameters of scallop mantle seasoning material with antioxidant activity by enzymatic hydrolysis coupled with Maillard reaction. Methods Scallop mantle was used as raw material to prepare scallop mantle seasoning material by enzymatic hydrolysis, and Maillard reaction was used to enhance the antioxidant activity of seasoning material. Taking degree of hydrolysis as index, the effects of addition amount of compound protease, enzymatichydrolysis temperature, enzymatichydrolysis time and pH on the enzymatic hydrolysis effect of scallop mantle were investigated by single factor test, and the optimum conditions of enzymatic hydrolysis of scallop mantle were determined by orthogonal experiment. The scallop mantle hydrolysates mixed with glucose were heated for Maillard reaction, the browning degree, antioxidant activity and sensory evaluation of the sample was determined. Results The optimal enzymatic hydrolysis of scallop mantle was as follow: The additive amount of enzyme was 3%, the temperature was 50℃, the time was 8 h, and the pH was 8. After 3.0 h of Maillard reaction with glucose at 110℃, 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging activity of scallop mantle seasoning material was enhanced by 1.7 fold, and the scallop mantle seasoning material tasted delicious with a strong aroma but not fishy smell. Conclusion Under the optimal process parameters, the scallop mantle seasoning material prepared by Maillard reaction has good antioxidant activity. This study can provide theoretical supports for the development of functional seasoning material and high-value utilization of scallop mantle.
