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 (T) and immobilized water (T) decreased significantly. However, the free water (T) increased significantly. Quality determination showed significant decrease in total sulfhydryl and Ca-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-ATPase, while significant positive correlation with disulfide bonds, respectively. The correlation between water distribution index and Ca-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.
本研究评估了凡纳滨对虾在部分冷冻储存过程中水分变化与品质劣化之间的相关性。检测到横截面积和等效直径显著增加，但冰晶的圆度和长度呈现不规则生长。在储存期延长过程中，结合水（T）和固定水（T）显著降低。然而，自由水（T）显著增加。品质测定表明，储存期间总巯基和Ca-ATP酶显著降低，但二硫键显著增加。相关性分析表明，横截面积分别与总巯基和Ca-ATP酶呈显著负相关，而与二硫键呈显著正相关。水分分布指数与Ca-ATP酶、二硫键之间的相关性分别显著。借助阿伦尼乌斯模型建立了关于横截面积和等效直径大小的冰晶生长预测模型。
