Technological parameter of preservative on Antarctic krill was optimized using response surface methodology,based on concentration of preservative,soaking period and temperature as well as sensory evaluation and storage period as testing indexes.The optimal technological parameters were preservatives concentration 21.80 g/L,soaking temperature 6.1 ℃ as and soaking time 6.56 min.Under the above condition,the practical comprehensive score was the highest and was close to the theoretical value,which exhibited the model was selected correctly.In addition,the optimal technological parameter was verified by testing texture analysis,color and muscle slice.The experimental results exhibited that the qualities of Antarctic krill in verification group was much better than control group,which meant that technological parameters played roles in qualities control.
