PURPOSE:To prevent the discoloration of fish, by freezing a fish body at a relatively high temperature and storing the body actively preventing the contact with oxygen, thereby preventing the oxidation of hemoglobin and myoglobin. CONSTITUTION:A fish body is frozen at -2--10 deg.C and stored under a pressure of 2-5atm thereby forcibly preventing the contact of the fish body with oxygen. As an alternative method, a fish body is frozen at the above temperature, sliced, and sealed in a pack containing non-oxidative gas such as carbon dioxide gas, thereby forcibly preventing the contact of the fish body with oxygen. |
