Now it's spring, because spring and summer are rainy seasons, and the air humidity is relatively high, which will cause a variety of molds to multiply in large quantities. If the food is put for a long time, it will become moldy and deteriorated. The following is to introduce several methods of food mildew prevention and preservation.
1. Fresh keeping of raw meat
If you can't eat all the raw meat bought in summer, wrap it in a clean wet cloth soaked in vinegar, and it will remain fresh even after three or five days.
2. Preservation of fish
The live fish bought back in summer can live for 1-2 days by lifting the fish's gills by hand, and then dipping it in vegetable oil or sesame oil and smearing it on the gills.
3. Preservation of lard
When the lard is refined and put into the oil container, put a little white sugar (50g sugar for 500g oil) on it, mix it evenly and cool it, then seal it up, so as to keep the flavor unchanged for a long time.
