For fruits and vegetables, freshness mainly depends on three aspects: first, try to inhibit respiration to reduce the loss of internal nutrients, such as using low temperatures or adding carbon dioxide; second, inhibit the growth of bacteria to prevent spoilage, such as using bacteriostatic agents; third, control transpiration to reduce water loss, maintain a certain humidity, and retain a fresh state. Food preservation tips even better than a refrigerator!
Wrap leftover salad in plastic wrap and place a paper towel inside.
Soaking strawberries in vinegar water can keep them fresh.
Storing potatoes and apples together can prevent sprouting.
Store leftover green onions in a plastic bottle.
Store green vegetables in a sealed plastic bag in the refrigerator.
Onions can be stored for up to six months if hung up.

Mushrooms are better stored in a paper bag than a plastic bag.
Wrap the crown of the bananas in plastic wrap to also extend their shelf life.
Pour leftover coffee into an ice cube tray and freeze it in the refrigerator. The next time you drink coffee, use these cubes as ice. They won't dilute the flavor of your coffee as they melt.
When storing fish in the refrigerator, it often becomes too dry. This can be prevented by freezing it in salt water.
Special reminder: Do not overstuff the refrigerator. It should be filled to about 60% capacity to allow for cold air circulation.
