The refrigerator is one of the necessary appliances for every household. Many people put food in the refrigerator to prolong the storage time of food. However, sometimes the food stored in the refrigerator will be found to be more perishable than that stored at room temperature, which will shorten the shelf life of the food. Here are 1 kinds of foods that can't be stored in the refrigerator, I hope to help you!

1. Starchy foods

Starchy foods such as steamed bread, flower rolls and bread can't be put into the refrigerator, which will speed up their drying and hardening. If they can't be eaten in a short time, they can be sealed and frozen in the freezer.

In addition, bread and biscuits should not be stored together, so that the moisture in the bread will be transferred to the biscuits, making the biscuits soft and the bread hard, which is not good for both.

2. Chocolate

After the chocolate put in the refrigerator is taken out, it is easy to appear frosty on the surface, which not only loses its original mellow taste, but also facilitates the reproduction of bacteria. Rui Lili said that the best temperature for storing chocolate is 5℃-18℃.

it can be sealed with plastic bags before being stored in the refrigerator. When you take it out, don't open it immediately, let it slowly return to room temperature before eating.

3. Fish

Fish in the refrigerator should not be stored for a long time. The refrigeration temperature of household refrigerators is generally-15℃, and the best refrigerator can only reach-2℃. When the storage temperature of aquatic products, especially fish, is below-3℃, fish tissues will be dehydrated or otherwise changed. For example, crucian carp will be prone to rancidity, meat quality changes and so on.

4. Medicinal materials

Medicinal materials should not be put in the refrigerator. If the medicinal materials are put in the refrigerator and mixed with other foods for a long time, not only are all kinds of bacteria easy to invade the medicinal materials, but they are also easy to get wet, which destroys the medicinal properties of the medicinal materials.

Therefore, for some valuable medicinal materials, such as ginseng, velvet antler, gastrodia elata, codonopsis pilosula, etc., if they need to be preserved for a long time, they can be put in a clean glass bottle, then put in a proper amount of glutinous rice which is fried to dark yellow with slow fire, put it in after cooling, seal the bottle cap and put it in a cool and ventilated place.

5. Tomatoes

After being frozen at low temperature, the meat of tomatoes is bubbly, soft and rotten, or cracked, with dark spots on the surface, uncooked and tasteless, and in severe cases, rotten.

Introduction to this article: Many people like to buy a lot of food and store it in the refrigerator. In fact, this is not correct. Some foods should not be put in the refrigerator. Let's find out!

6. Cucumber and green pepper

Cucumber and green pepper will turn black, soften and taste bad if stored in the refrigerator for a long time. Cucumber also grows sticky hair. Because the temperature stored in the refrigerator is generally about 4℃ to 6℃, the suitable temperature for cucumber storage is 1℃ to 12℃, and the green pepper is 7℃ to 8℃, so it should not be stored for a long time.

7. Green leafy vegetables

When green leafy vegetables are put in the refrigerator, not only the leaves will rot faster, but also toxic nitrite may be generated due to the action of enzymes and bacteria.

8. Bananas

If bananas are stored below 12℃, they will turn black and rot.

9. Fresh Litchi

If Litchi is left at ℃ for one day, its skin will turn black and its pulp will turn sour.

1. Strawberries

Strawberries are stored in the refrigerator, which not only have foaming pulp and greatly reduced taste, but also are prone to mildew.

Tips for storing food in the refrigerator:

1. At the door frame of the refrigerator.

The temperature here is relatively highest, which is convenient to take. It is suitable for storing some foods that can be temporarily stored at room temperature, which are not easy to spoil or are about to be eaten, such as eggs, cheese, unopened drinks, condiments and so on.

2. The upper floor is near the door.

The temperature of the upper floor is slightly higher than that of the lower floor, which is suitable for placing cooked food, yogurt, desserts, etc. which can be directly eaten. These foods should avoid being too low in temperature.

3. At the back wall of the upper floor.

The temperature at the back wall is lower than that near the door, which is suitable for storing foods that are not afraid of freezing, including leftover food, leftover soybean milk, leftover bean products, milk and so on. It should be noted that leftovers should be packed in fresh-keeping boxes or sealed with plastic wrap to avoid cross-contamination and odor.

4. The lower floor is near the door.

It is suitable for putting all kinds of green leafy vegetables and fruits. This kind of food should be kept close to the inner wall of refrigerator to avoid frostbite.

5. At the lower back wall.

foods that are not cooked well but need to be preserved at low temperature, such as tofu, and foods that are tightly packed and not afraid of cross contamination are also suitable here, such as bagged cooked meat.

6. Fresh-keeping layer.

The chilled meat, chilled fish and other aquatic products to be eaten within 24 hours after purchase should be placed in the fresh-keeping box at the bottom of the cold room.

If the refrigerator has a special temperature-adjustable fresh-keeping layer, it is best to put the meat in the fresh-keeping layer at-1℃-1℃.

if there are two drawers in the fresh-keeping layer, it is recommended that fish and meat be placed in the lower layer and stored separately from the fruits that need to be refrigerated.

which foods need to be kept in the refrigerator

green tea

Different kinds of tea have different storage methods in summer. Among them, green tea needs to be stored in the refrigerator. Green tea belongs to non-fermented tea. High temperature will accelerate the degradation of chlorophyll in green tea, and chlorophyll will be continuously transformed into pheophytin, and bright green will turn dark brown. The automatic oxidation of substances such as tea polyphenols at high temperature will also intensify.

According to the research, every 1℃ increase in temperature will accelerate the browning rate of green tea by 3~5 times, and the tea leaves are easy to age and deteriorate. The optimum storage temperature of green tea leaves is -5℃. If the temperature is too high, amino acids, sugars, vitamins and aromatic substances in tea will be decomposed and destroyed, which will reduce the quality, aroma and taste.

In addition, catechin is helpful to prevent heart disease, cancer, Alzheimer's disease and other diseases in green tea, but a study published in the American Journal of Food Science pointed out that the content of catechin in green tea decreased after it was left at room temperature for six months. Therefore, the storage of green tea needs to be put in the refrigerator, and the tea leaves should be put in a tea can and sealed, covered with plastic bags, and then put in the refrigerator after sealing.

Shrimp and other seafood products

As long as most seafood products die, they will go bad in less than half a day in the hot summer. However, dried seafood such as shrimps are prone to quality deterioration due to moisture absorption at room temperature, which not only produces pungent ammonia smell due to the decomposition of protein, but also produces carcinogenic nitrosamines. Therefore, both fresh seafood products and dried seafood products must be put in the refrigerator.

sauces and condiments

Although many sauces and condiments can be temporarily stored at room temperature, the problems of fat oxidation and flavor change will occur slowly. Therefore, if you feel that you can't finish it in two weeks, you'd better put it in the refrigerator. The less salty sauces, such as salad dressing and tomato sauce, must be put in the refrigerator after opening. Curry powder, spiced powder and other spices will have better quality at low temperature than at room temperature after a few months.

in the final analysis, the reason why these foods need to be stored in the refrigerator is the temperature, and each food has its own storage temperature. If the refrigerator at home can be divided into multiple zones and the temperature can be accurately controlled by zones, the nutrition of food can be preserved to the maximum extent and food spoilage can be prevented.

therefore, when purchasing refrigerators, the design of different temperature zones is also a problem that many consumers will consider. Midea refrigerator has a brand-new six-door four-temperature zone fresh storage design, which can realize the partition preservation of food and healthy classification and preservation. In addition, there is a double independent greenhouse with a width of-18℃ ~ 7℃, and a variety of scientific preservation modes can be selected at any time to effectively retain nutrition and freshness.
