Controlling freezing point of cobia by using freezing point regulators

    Abstract
  • We investigated the effect ofthree kinds of freezing point regulators including CaCl2, NaCl and VC on cobia (Rachycentron canadum) by single factor comparison experiment. 4% CaCl2 treatmentfor 60 mindecreased 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 NaCl and VC. The results show that treatment with 3% NaCl and 0.3% VC for 60 min decreased freezing point by 60.4%, from -1.01 ℃ to -1.62 ℃.
