Different types of preservation conditions are very different. Nutritionists reveal 8 major concerns about summer foods

As the time enters summer, the weather becomes hot, so pay more attention to high temperatures that may cause food to become more delicious. Eating them may cause gastritis. It is important to keep food properly. Nutritionist Li Lici said that different types of food, such as fish, milk, eggs, rice or fruits and vegetables, have different preservation conditions, but as long as you master the key guidelines for maintaining various ingredients, you can enjoy the food healthily without any burden.

1. Seafood and meat. Fully sealed cold rice

If seafood and meat are not eaten that day, it is recommended to place it in -18° C. Environmental cold rice can inhibit bacterial growth, but remember to be "fully sealed". Do not tie or roll up the entire plastic bag when you buy it home. This may cross-stain or affect other foods.

2. Refrigerate when the room temperature is overheated

Some eggs are sold in a temperature environment. If you eat quickly after buying it home, you can keep it in the room temperature, but the room temperature is more than 28° C or the ventilation condition is not good, it is recommended to store it in a refrigeration safely. Eggs that have been refrigerated should be kept in refrigerated condition and should not be moved back to the room temperature, because repeated temperature changes can easily lead to deterioration; eggs have air holes, so it is recommended to store them in original boxes or egg boxes to avoid being fresh and unhealthy for a long time.

3. Vegetables and fruits are put in sealed bags

Leaf Vegetables and put in 7° Refrigeration below C can increase the leaves of the vegetable to make it yellow, but it should be properly wrapped or put in a sealed bag (box) to avoid direct exposure to the refrigerator and causing drainage. It is not recommended to use cabbage for papers. The papers are easy to absorb moisture and become damp and damp. Do not wash them before storage. The moisture will accelerate the growth and decay of bacteria. Just clean them before eating.

Skinned or hard root-locked fruits, such as sausage, cucumber, winter melon, etc. If the refrigerator is insufficient, it can be stored in a short space in the room. Some fruits should be separated from vegetables, such as apples, pears, papaya and other enzymes, to avoid accelerating the ripening of vegetables too quickly. It is recommended to use bags or boxes to separate them.

4. Rice and noodles must be separated from moisture

rice and dry noodles must be separated from moisture. They can be placed in a sealed rice jar or insulated box, stored in a room-drying and drying area and cannot be refrigerated, otherwise it will easily absorb moisture and change quality; the damp noodles must be stored in a refrigerated manner.

5. Dairy products: Unseal and eat as quickly as possible

Milk and dairy products must be stored in 7°C; refrigerated environments below C should be put back as soon as possible after taking them out from the refrigerator, because the nutritional ingredients, fat, carbohydrate and lactose of dairy products are high, which is easy to breed bacteria; but they should not be refrigerated, otherwise it will change the taste and taste.

The long-lasting milk can be stored in the room without opening the seal. Once it is opened or refrigerated, it will be stored in comparison with fresh milk. After the milk product is opened, it must be eaten as soon as possible, especially large packages. Repeatedly opening it can easily increase the risk of dyeing. It is recommended to buy a small portion and then open it after eating it.

6. Fruit sauce and flavoring ingredients need to be refrigerated.

Fruit sauce ingredients are natural products. Refrigerated after unsealing; Fruit sauces with complex ingredients, if the seal is well after unsealed, part of them can be stored in the room, but the product label still needs to be paid attention to.

There are many types of flavoring ingredients, and the storage methods are different. The common points are tight, sunny and low temperature. For example, oil, sugar, flavor, salt, vinegar, etc. do not need to be placed in the refrigerator. "Chang" is a major point. Avoid placing it under the kitchen gas or above the kitchen, etc.; most of the others should be placed in the refrigerator, otherwise it will easily change quality or get out of flavor. Before purchasing, you should read the storage method and time.

7. Cooked food can be put in the refrigerator without burning

Many people will wait until the cooked food is completely cold before putting it in the refrigerator. Li Lici said that as long as the boiling is not so burning, it should be avoided to keep the dangerous temperature belt at 7 to 60°C for a long time. If you cook too much, for example, cure a large beef, you can then separate and store it to avoid repeated heat in the whole beef.

As for the containers to be stored, it is recommended to choose a sealed and insulated box with glass or stainless steel. If plastic containers are used, it is necessary to confirm that it is food-grade, heat-resistant and no harmful substances are found. If the cover is plastic, make sure that the food does not touch the plastic cover, or avoid the cover when burning.

8. Leftovers It is not recommended to cool the leftovers

. Because they have been exposed to saliva or tableware, the bacterial dye or the quality is higher. Li Lici said that it should be eaten within the next meal or within 24 hours. It is not recommended to cool it again; if you want to refrigerate, you can put it in before boiling, and pay attention to the quality of the containers.

Li Lici reminds that the ingredients in the refrigerator should not be filled with full, and the cold air circulation space should be kept. It is recommended not exceed 80% full. The outlet should also avoid stacking items and cultivate the habit of "first-in, first-out", that is, the ingredients stored in ice should be taken first.
