How to save in the refrigerator:

1, visceral saline immersion method. Fish can be hollowed out without washing and scaling, soaked in 10% salt water, and can be preserved for several days without deterioration.

2, mustard preservation method. Apply a proper amount of mustard to the surface and inner cavity of the fish (which has been opened), or evenly spread around the container for holding the fish, and then put the fish and mustard in a closed container, which can be stored for 3 days without deterioration.

3. Hot water treatment method. After eviscerating fresh fish, put it in hot water (80℃ ~ 90℃) that won't boil, take it out after a short pause. At this time, the appearance of fresh fish has turned white, and then it can be stored on ice, which can double the storage time of fresh fish without hot water treatment.

4. Steam treatment method. Clean fresh fish, cut into shapes suitable for cooking, and put them in breathable plastic bags. The whole bag of fish can be kept fresh for 2 ~ 3 days after being sterilized by hot steam.

5. Alcohol therapy. Pry open the mouth of fresh fish, drop white wine into the mouth, and put it in a cool and ventilated place to prevent corruption and deterioration. Cut a few knife flowers on the packaged fresh fish, and then pour a proper amount of beer into the fish body and fish cavity, so as to maintain the quality and freshness before cooking. General refrigeration 1~2 days, freezing 90~ 180 days.
