鲫鱼块冰点调节剂的研究

Reseach of Freezing Point Regulators of Crucian Crap Block

研究了不同冰点调节剂对鲫鱼块冰点的影响,并通过响应面优化设计对几种较好的冰点调节剂进行复配,较大幅度的降低了鲫鱼块的冰点。实验结果表明:氯化钙、山梨醇、氯化钠是较好的冰点调节剂,当山梨醇添加质量分数为1.74%,氯化钙添加质量分数为5.15%,氯化钠添加质量分数为2.13%时鲫鱼块的冰点降低到-1.6℃左右。

In this manuscript, the effect of different freezing point regulators on the the crucian crap block freezing point was investigated and optimized through the response surface design. The optimum conditions described as follows：sorbitol content 1.74%, calcium chloride content 5.15%, sodium chloride content 2.13%. with the optimum conditions, the freezing point of the crucian crap block decreased to -1.6 ℃.
