Tuna/salmon refrigerator
This is a common and simple preservation method, in addition to crushed ice, generally can also be added 3~7% NaCl when making ice, an appropriate amount of sorbitol and compound food phosphate, the fish is washed and cut into 3~5cm thick fish fillets, put into a plastic film bag, and then put into a plastic frame in the form of layers of fish layer ice in 2~-4 °C cold storage storage, small tuna can also be not sliced, directly covered with crushed ice, with this method can generally make tuna freshness period up to 40 days.

Tuna/salmon fridge:
1. Freezing preservation method
This is a common and simple preservation method, in addition to crushed ice, generally can also be added 3~7% NaCl when making ice, an appropriate amount of sorbitol and compound food phosphate, the fish is washed and cut into 3~5cm thick fish fillets, put into a plastic film bag, and then put into a plastic frame in the form of layers of fish layer ice in 2~-4 °C cold storage storage, small tuna can also be not sliced, directly covered with crushed ice, with this method can generally make tuna freshness period up to 40 days.
2. Micro-freeze for freshness
The 3~5cm thick tuna fillet is slightly frozen and preserved under -1~-3 °C conditions, generally can be kept fresh for 8~10 days, the color and flavor of the meat remain unchanged, and can be used as sashimi.
3. Freeze Law
Because the oxidation rate of tuna myoglobin is 1~3 times faster than that of mammals, and the temperature effect is particularly obvious, in order to keep the color, meat taste and taste of tuna in long-term storage, generally using frozen storage, with the improvement of people's quality requirements and technological progress, the temperature of frozen storage is getting lower and lower, from -18 °C→-25 °C→ -35 °C→-50 °C→-60 °C, according to Oto's research, in the 6-month freezing cycle, The production rate of ferroglobin is about 35% lower than that of -18 °C when frozen at -33 °C, and only 78% higher than that of -2V freezing, while the energy consumption is much lower, therefore, according to the existing situation in China, it is recommended to use -35 °C freezing. If the shelf life is to be extended further, a lower freezing temperature is required. In addition, it must be noted that tuna must also pass quickly through the -4°C→-7°C temperature range in frozen storage, otherwise the muscles are also prone to discoloration. It can be used for the preservation of biological materials, plasma and special materials for low temperature test, suitable for blood stations, hospitals, epidemic prevention stations, electronic chemical and other enterprise laboratories and distant-water fishery companies.
