What are the three best ways to preserve food?

Put a fresh celery and bread together in a plastic bag to keep the bread fresh.

Store milk

(1) Fresh milk should be immediately placed in the shade, preferably in the refrigerator.

(2) Don't expose the milk to sunlight or light. Sunlight and light will destroy several vitamins in milk and make it lose its flavor.

(3) Put the milk in the refrigerator and cover the bottle cap to prevent other odors from entering the milk.

(4) Pour the milk into containers such as cups and teapots. If you haven't finished eating, cover it and put it back in the refrigerator. Never pour it back into the original bottle.

(5) supercooling also has a bad effect on milk. If milk freezes into ice, its quality will be damaged. So don't freeze the milk, just put it in the refrigerator.

peanut oil

Heat peanut oil and soybean oil in a pot, add a little pepper and fennel, and pour the oil into an enamel or ceramic container for preservation after it cools. Not only does it not change its taste for a long time, but it tastes particularly fragrant when used in cooking.

Fresh eggs don't go bad easily when they stand upright.

After fresh eggs are placed for a period of time, the yolk is easy to stick to the shell or yellow. This is because mucin in protein will be slowly diluted under the action of protease, losing the function of fixing egg yolk. If the egg head is placed vertically, there is an air chamber in the egg head, and the gas inside will make the yolk unable to get close to the eggshell. Therefore, fresh eggs are placed vertically, which is not easy to stick to the shell or yellow.

Simple preservation of vegetables

Remove the rotten parts of vegetables, put them in plastic bags, tie the bags tightly and put them in a cool and dry place. This method can generally keep vegetables fresh for 10 ~ 15 days. This method is more suitable for preserving cucumbers, sweet peppers, lettuce, small green peppers, parsley and immature tomatoes.

Prevent pasta from hardening

Keeping pasta hard for a long time is the biggest headache for people. For example, steamed bread will be as hard as stone after a while; Putting fried dough sticks for a few days is like chewing a rubber band; When bread and cakes are left for a period of time, their skins will shrink and taste like corks. Some people think that the hardening of pasta is caused by evaporation of water, which is not entirely correct. In fact, it is mainly a phenomenon of "starch retrogradation", also known as "starch retrogradation". The prevention method is to put the freshly made pasta in the refrigerator while it is hot and cool it quickly. Families without conditions can be put in cabinets or in the shade, or.

Prevent tomato sauce from spoiling

After opening a can of tomato sauce, if you can't finish it at once, it will go bad after a while. If you open a can of tomato sauce, steam it in the pot before eating it, and eat the remaining tomato sauce, which will not go bad for a long time.
