| 摘 要： | 为了研究盐分对鱼类冻结特性的影响,将5种新鲜鱼类分别浸泡在盐度为0％、5％、10％ 、20％的盐溶液中24 h后,采集样品的温度变化数据,绘制出冻结曲线,比较各盐度下各冻结特性值的不同.结果表明:盐处理后鱼类的冻结点显著降低,且随着盐度的增加,冻结速率降低,最大冰晶生成带通过时间延长,过冷却现象明显.

| Abstract: | In order to research the influence of salt on freezing characteristics of fish, five kinds of fishes were
immersed in the salinities of 0%, 5%, 10%, 20% salt solution for 24 h, the temperature data were collected using the
SATO SK-L210T thermometer, the freezing curves were drawn and the freezing characteristics were compared. The results
showed that the freezing point decreased significantly after salt treatment, with the salinity increasing, the freezing rate
decreased, the zone of maximum crystallization time prolonged and the super cooling phenomenon was obvious. |
