Turn: Good packaging habits, too much trouble

Packaging seems uncommon in the past few years. People always think that it is a little boring to bring leftovers home, or they feel that packaging means they have no money. Today, this situation has actually changed, and packaging is becoming increasingly popular. Now let's take a look at the knowledge in this package.

First, the packaged food needs to be cooled down and then placed in the refrigerator. This is because hot food suddenly enters the low temperature environment, the food center is prone to qualitative changes, and the hot air brought into the food will cause the condensation of water vapor, promote the growth of mold, resulting in

The mildew of food in the refrigerator.

Second, the food to be packed must go back to the pot. The food stored in the refrigerator must go back to the pot after being taken out. This is because the temperature in the refrigerator can only inhibit Bacterial reproduction and cannot completely destroy them. If you are not heated before eating, it will cause discomfort after eating, such as dysentery or diarrhea.

Third, the leftovers should not be stored too long. The storage time of leftovers should not be separated. The leftovers are eaten at noon in the morning, and the leftovers are eaten at night at noon. It is best to eat them within five or six hours. Because in general 100 ℃ In a few minutes, it can kill some bacterial viruses and parasites. However, if the food is stored for too long, the bacteria in the food will release chemical toxins and there is no way to heat these toxins.

Fourth, vegetarian dishes should not be packed. Because there is usually less salt in the process of making vegetarian dishes, the bacteria in a long dish will multiply in a large amount when the temperature of the prepared vegetarian dishes is relatively high, nitrate is reduced to nitrite under the action of bacteria. Nitrite is easily synthesized with amine in nature, and nitroamine is a strong carcinogenic substance. If we eat the remaining vegetables for a long time, this is not good for our health.

Next, let's talk about some of the issues that should be paid attention to After packaging fish, meat, seafood, and starch.

I. Fish:

Bacteria in this type of food can easily multiply, and the Escherichia coli bacteria on the top are 20 ℃ In about 8 minutes, the bacteria multiply every eight minutes, and within five or six hours, the bacteria change to 0.1 billion. This quantity is enough to make your stomach feel unwell. Therefore, the packaged fish must be heated for four to five minutes. However, after a long period of heating, the full-price protein, fish fat and rich vitamins contained in the fish will lose the nutritional value of the nutrients beneficial to the human nervous system.

Ii. Meat:

Meat and animal foods are packed and reheated. It is best to add some vinegar. Because these foods are rich in minerals, they will overflow with water after being heated. Then, some vinegar is added during heating, and the matter will become calcium acetate when it encounters acetic acid, which not only improves its nutrition, but also facilitates our body's absorption and utilization. If you want to enrich the taste, you can also add some sugar to adjust the flavor.

Iii. Seafood:

When heating shellfish and seafood foods, it is best to add other ingredients such as liquor, onion, ginger, etc. This not only improves freshness, but also has a certain bactericidal effect, it can kill the bacteria that lurk in it and prevent gastrointestinal discomfort.

Iv. Starch:

Package back some starchy foods such as rice cakes. It is best to finish eating them within four hours because they are easily infected with staphylococcus. This type of bacterial toxin will not be decomposed under high temperature heating, and will not solve the problem of deterioration. Therefore, if you haven't finished eating in a short period of time, do not eat it even if it looks bad.

Now we have good living conditions, but we cannot forget to save money. According to a survey on packaging, more than 70% of people expressed willingness to pack, which is also a waste of money. Obviously, many of us have maintained a good habit of thrift and thrift. However, packaging is a result of blindly ordering food, which is better than packaging.
