Summer food preservation method

Cereals and beans

keep dry

Cereals, beans, etc. In hot and humid weather, it is easy to get damp, mildew and insects. Therefore, the preservation principle of whole grains and beans is to ensure that the grains are dry first, bottle them when the weather is dry, and close the lid quickly.

When buying grain and beans, priority should be given to buying small vacuum packaging. When the weather is sunny and dry, open the vacuum package and put it into a small bag that can be eaten in a week or two, then drive out the air in the bag and store it in the shade.

Sometimes, unprocessed whole grains may be mixed with eggs. You can seal the grain in an impermeable bag and freeze it for two or three weeks, then gradually raise the temperature to room temperature in a closed state, and then open it when eating, so that insects are not easy to grow. It is also beautiful and neat to keep whole grains and beans in beverage bottles.

Bread, jiaozi.

Low temperature storage

It tastes just as good. If you cook too many stuffed dishes at one time, you can subcontract and freeze them.

remainder

Sealed refrigeration

Leftovers are the favorite of bacteria. The longer they are left at room temperature, the more microorganisms will multiply and the more likely they will go bad.

1, there are more nitrates in vegetables, which may be converted into toxic nitrite during storage, while there are fewer harmful substances in meat dishes during storage, so meat dishes without vegetables are better.

Leftovers should be stored in the refrigerator within 2 ~ 3 hours. All leftovers should be wrapped in plastic wrap or put in a covered box. If you know you can't finish this meal, you might as well pack it in advance.

dairy produce

Pay attention to the storage time and conditions.

When yogurt is placed at room temperature, beneficial bacteria such as lactic acid bacteria will die quickly, and the taste of yogurt will be too sour. If pasteurized milk is kept at room temperature for a long time, it will deteriorate due to the proliferation of bacteria.

1. Yogurt and pasteurized milk must be put in the refrigerator as soon as possible, and it is best to drink them within a few hours after opening.

Tetra Pak Fang boxed milk is sterilized and completely sealed. Bacteria and oxygen can't get in, so it can be stored at room temperature. However, once you open the package, things are completely different. Bacteria and oxygen will also come in rudely. If you don't finish it in time, the rest must be put in the refrigerator.

Try to pour the oil into the oil pan within one week. Try to finish the oil in the vat within three months. Remember to clean the oil pot regularly.

condiment

See the storage conditions clearly

Generally, seasoning itself has a certain antiseptic effect, but improper storage may lead to mildew. Therefore, before storing the seasoning, you must carefully look at the storage conditions and storage period on the package.

1. Salt, sugar, chicken essence, etc. Just keep it in a cool and dry place to avoid moisture absorption and caking.

2. Curry powder, spiced powder, pepper, star anise, cinnamon and other spices have certain insect resistance and antibacterial effect, but there is also the possibility of mildew, and the longer it is opened, the greater the aroma loss. It is recommended to give priority to buying small packages. If you have bought a large package, you'd better take it out in small quantities and seal the rest to avoid moisture absorption and deterioration.
