1, sushi is usually stored in a closed plastic box, or wrapped with plastic wrap for "moisturizing". Leave it at room temperature without refrigerator for one day at most.

2. In order to preserve sushi for a long time, you can put it in the "freezer". When eating, take it to the "cold room" and thaw it slowly.

3. It won't go bad within two weeks. Pay attention to it when you put it in the refrigerator: seal it with plastic wrap, so as to prevent food from smelling. Refrigeration at 4-6 C is the best. Put sushi in shallow dishes so that the temperature of each part of sushi is balanced, and avoid the deterioration of sushi due to too deep bowl and too high temperature in the middle.
