Abstract

Highlight: Cross-sectional area and equivalent diameter could be used for prediction of ice crystal. Cross-sectional area showed significant correlation with protein properties. T21, T22 revealed significant correlation with Ca 2+ -ATPase and disulfide bonds. Ice crystal on muscle protein deterioration is more significant than water distribution. Abstract: The correlation between water changes and quality deterioration of Litopenaeus vannamei during partial freezing storage was evaluated in this study. Significant increases in cross-sectional area and equivalent diameter are detected, but the roundness and longiness of the ice crystals show irregular growth. Within the extension of storage, the bound water (T2b ) and immobilized water (T21 ) decreased significantly. However, the free water (T22 ) increased significantly. Quality determination showed significant decrease in total sulfhydryl and Ca 2+ -ATPase, but significant increase in disulfide bonds during storage. Correlation analysis revealed that cross-sectional area showed significant negative correlation with total sulfhydryl and Ca 2+ -ATPase, while significant positive correlation with disulfide bonds, respectively. The correlation between water distribution index and Ca 2+ -ATPase, disulfide bonds was significant, respectively. Predicted models for the growth of ice crystals with respect to cross-sectional area and equivalent diameter size have been developed with the help of the Arrhenius model.
