/>

The refrigerator is an indispensable "treasure chest" in each family's life. Many people put all kinds of ingredients, pickles, leftovers leftovers, and even masks and Chinese medicines, etc., and finally cause severe skewers!

However, the refrigerator is not universal. If it is not used properly, it may cause some foods to corructively and produce harmful pathogenic bacteria. What are the hidden dangers in the refrigerator and how should different foods be placed? Today, I would like to ask Professor Feng Shuangqing, School of Food Science and Nutrition Engineering, China Agricultural University to give us a good popular science!

First of all, experts do not recommend putting the mask in the refrigerator, which is too cool to be good for component absorption. Some people have sensitive skin. After taking a bath, pores are diastable, and the cold mask is applied, which is more likely to cause allergies. Therefore, the mask is generally preserved at room temperature. If the refrigerator is placed, it can only be stored in the short term, and the temperature is used after taking it out. The effect is better.

Secondly, the pink or very dry Chinese herbal medicine cannot be placed in the refrigerator. The humidity in the refrigerator is large, and this type of Chinese herbal medicine is easy to rot and deteriorate after absorbing moisture.

However, some injections are possible, such as insulin, which can be kept refrigerated from 2 ~ 8 ° C in the refrigerator. Note that after taking out from the refrigerator, you need to heat up before using it.

How to save meat, eggs, vegetables and vegetables?

1

Fruit and vegetables are difficult to keep fresh, and the refrigerator time is different

Professor Feng told us that fruits and vegetables are actually living bodies. They need to breathe and release energy, release ethylene gases, and will wither after the loss of moisture, so it is the most difficult to save. Different types of fruits and vegetables have different lengths.

2

Meat storage to see fat, the temperature needs -18 degrees

The stored meat, such as poultry, fish, etc., mainly depending on the thickness of the ingredients, the thicker the fat, the easier it is to oxidize, and the storage time is relatively short.

There are pathogenic bacteria in the refrigerator, so do a good job of cleaning and enjoying health

Many people think that the refrigerator is low temperature and must be particularly safe. In fact, there are pathogenic bacteria in the refrigerator, such as cold -add bacteria that are not afraid of cold, which can survive at -18 ° C. There are more bacteria in the refrigerator, such as E. coli and Salmonella, which are bacteria that are damaged to human health. Therefore, we must do a good job of cleaning the refrigerator regularly.

Tropical fruits and vegetables with fruit characteristics, such as cucumber and tomatoes, need to be packed with fresh -keeping bags. Note that the fresh -keeping bag will not be sealed first, wait for four or five hours or the food is cold before sealed. Avoid the heat released by food, forming water vapor, causing food to rot and corrupted. Generally, it is preserved for more than 7 days.
