Research on the Effect of Green Tea and Licorice on the Fishy Removal of Silver Carp and Process Optimization
The extracts of green tea and licorice were used to decontaminate the silver carp.The decontamination effect of the green tea treatment group and the licorice treatment group on the silver carp was analyzed through single-factor experiments.After the fishiness evaluation and electronic nose measurement,it was concluded that the green tea treatment group had a better decon-tamination effect than the licorice treatment group.Through orthogonal experiments,it is concluded that the fishy removal effect is best when the concentration of green tea solution is 2%,the fishy removal time is 40min,and the fishy removal temperature is 30℃.At the same time,the odor components of silver carp and silver carp after fishy removal are extracted by distillation,and gas chro-matography-mass spectrometry(GC-MS)is used to analyze the changes in the volatile components of silver carp before and after fishy removal.The results showed that the volatile fishy smell was significantly reduced after the fishy removal with green tea.Green tea has no safety risks in fishy removal,and provides technical support for improving the processing and utilization value of silver carp.
