| 摘 要： | 研究几种冰点调节剂对于军曹鱼（Rachycentroncanadum）冰点的影响。选取氯化钙（CaCl2）、氯化钠（NaCl）和维生素C（Vc）3种冰点调节剂，利用单因素比较法得出使用4％CaCl2浸泡处理60min可使军曹鱼冰点降至-1．21oC；用2％NaCl浸泡处理军曹鱼90min可使军曹鱼冰点由-1．01cC降至-1．36℃；使用0．5％V，溶液浸泡处理30min可使其冰点降至-1．30℃。因此选取NaCl和Vc 2种较好的冰点调节剂进行复配，再通过正交试验确定两者结合使用的最佳配比。结果显示，使用3％NaCl和0．3％V。共同处理军曹鱼60min为最佳，可使其冰点降至-1．62℃，下降了60．4％。

| Abstract: | We investigated the effect of three kinds of freezing point regulators including CaC12 , NaCl and Vc on cobia （ Rachycentron canadum） by single factor comparison experiment. 4% CaC12 treatment for 60 min decreased freezing point to - 1.21 ℃ ; 2% NaCl treatment for 90 min decreased freezing point from - 1.01 ℃ to - 1.36 ℃ ; 0. 5% Vc treatment for 30 min decreased freezing point to - 1.30 ℃. Orthogonal experiment was conducted to determine the best proportion between NaCI and Vc. The results show that treat- ment with 3% NaCl and 0. 3% Vc for 60 min decreased freezing point by 60.4%, from - 1.01 ℃ to - 1.62 ℃. |
