This is the method I have been using myself, and it is really effective:
Usually, "green leafy vegetables" are the easiest to dehydrate directly in the refrigerator. Before putting them in the refrigerator, they will be treated to keep them fresh for a long time.
(1) If the fresh vegetables bought back are too dirty, roughly clean the insect leaves, rotten leaves and dirty leaves, and never soak them; If you buy vegetables in the vegetable market (vegetable vendors will pour a lot of water on the vegetables to attract them by weighing), we can splash some water, but don't splash it too dry; If you buy food in the supermarket, the food itself will be very dry, so you must order some water for it. Don't order too much water, it will rot easily.
(2) Then put it into a plastic bag or food bag, and don't seal it too tightly. Leave some breathing holes for it to breathe. If convection can be generated, it is best to divide it into several small mouths in Dozza. This can prevent the water in vegetables and leafy vegetables from evaporating too fast, and you can catch your breath. Must be fresh!
(3) In addition, the storage position of "green leafy vegetables" in the refrigerator is very important. Putting their roots down in the freezer can effectively prolong the storage time and keep them fresh.
The following information is also important and can be used for reference.
Information 1 There is a knack for keeping fruits and vegetables fresh.
(1) Vegetables such as leeks and garlic yellow bought in winter can be wrapped in fresh Chinese cabbage leaves and stored in a cool place for a few days.
(2) Lettuce will gradually become soft and discolored as long as it is left for a period of time. You can remove the cabbage core, then put a wet tissue into the cabbage core to make the lettuce absorb water, take it out when the tissue is dry, and then put the lettuce in a fresh-keeping bag for refrigeration.
(3) Garlic, onion, ginger and pepper are mostly condiments, so it is best to keep their original appearance when they are preserved. Garlic is preserved in a similar way to onion. It can be placed in a net bag and hung in a cool and ventilated place indoors, or it can be placed in a special ceramic cylinder with air holes. Ginger is divided into old ginger and young ginger. Ginger is not suitable for cold storage, so it can be placed in ventilated places and sand. Young ginger should be wrapped in plastic wrap and kept in the refrigerator. (4) After peeling the fruit, if you don't eat it immediately, the air will oxidize the fruit after a while, making its surface turn light brown, which is very ugly. If the peeled fruit is soaked in cold boiled water, it can not only prevent oxidation, maintain the original color, but also make the fruit brittle and sweet.
Data Two fresh-keeping methods of daily edible vegetables
(1) Fresh-keeping of coriander: choose a large, bright green coriander with roots, bundle it into small bundles of about 500g, wrap it with a layer of paper (it is best not to see the green leaves), put it into a plastic bag, loosely tie the bag mouth, and put the bag in a cool place, with the roots of coriander facing up, and take it with you when eating. When stored in this way, the leaves of coriander can be fresh and tender within 7- 10 days. When storing coriander for a long time, you can cut off the root of coriander, remove the old leaves and yellow leaves, spread it out to dry for 1-2 days, then braid it and hang it in the shade to dry. You can soak it in warm water when eating. The color of coriander is green instead of yellow, and the fragrance still exists.
(2) Preservation of eggplant. Eggplant skin is covered with a layer of wax, which not only makes eggplant shine, but also protects eggplant. Once the wax layer is washed away or mechanically damaged, it is easy to rot and deteriorate due to microbial invasion. Therefore, the eggplant to be preserved is generally not washed, but also protected from rain, bumps, heatstroke and high temperature, and stored in a cool and ventilated place.
(3) leek preservation. The newly bought fresh leek was tied with a small rope and put in a pot with its roots facing down. It wonn't rot for long Celery, Artemisia annua, onion, etc. You can also keep fresh in this way.
(4) Preservation of tomatoes. Choose tomatoes with complete fruit shape, good quality and medium maturity, put them in plastic food bags, tie the mouth tightly, put them in the shade, open the bags/kloc-0 times a day, and ventilate for about 5 minutes. If there is steam in the plastic bag, dry it with a clean towel and tie it tightly. The tomatoes in the bag will gradually mature and last for about 30 days.
Information three green leafy vegetables should be eaten like this.
(1) Buy and eat now. The fresher the vegetables, the higher the vitamin C content. If vegetables are stored for too long, the oxidase in vegetables will destroy vitamin C by oxidation.
(2) Wash before cutting. If you cut it first and then wash it, the vitamin C overflowed from the sliced vegetables will be dissolved in water and lost. Chopping vegetables should also be cooked quickly, which will easily lead to vitamin C oxidation after a long time.
(3) stir fry quickly. Heating for too long will seriously damage vitamin C. Although the fire temperature is high, but the time is short, it can quickly inactivate the oxidase in vegetables, so the loss of vitamins is relatively small.
(4) Starch thickening. Adding a small amount of starch during cooking can increase freshness ... >>
Can vegetables be stored in the refrigerator after washing?
Washing vegetables in the refrigerator is perishable, especially for vegetables that are not very fresh.
Suggestion: after washing, spread it out and dry it fully (especially leafy vegetables), then put it into food plastic bags, tie the bag tightly and store it in the refrigerator until the next day.

Hang vegetables and put them in a ventilated place. This is the way to store them until the next day. If you want to keep them fresh for a long time, you must take the refrigerator as the best way. At home, I always put vegetables in the snap box and put them in the refrigerator, so that vegetables and other foods can have a constant temperature and will not lose nutrition and moisture because of the low temperature. So some foods are most convenient to use the refrigerator.

Which vegetables can be put in the refrigerator? What can't?
Green leafy vegetables wither easily. To keep them fresh, it is indeed a way to put them in the refrigerator, but it is best to control the temperature of the refrigerator between 0 and 4 degrees Celsius, put a fresh-keeping bag outside or store them in a fresh-keeping box to achieve the effect of fresh-keeping. Remember that it is best not to wash before storage, and the storage time should not be too long, otherwise the dishes will be easily covered.
Tuber vegetables, such as potatoes, cucumbers and carrots, are not so delicate. Just keep it at room temperature, there is no need to put it in the refrigerator. It should be noted that tomatoes are not suitable for storage in the refrigerator. Because tomatoes are frozen at low temperature, the meat will bubble, the umami will disappear, it is not easy to cook, and it will be rancid and rotten in serious cases. )
Mango, persimmon, banana and other jam fruits.
The so-called jam fruits are those fruits that can be peeled and have jam-like pulp. Berry fruits will lose their fragrance and their skins will deteriorate at low temperature. For example, we all know that bananas are easy to turn black and rot when placed below 12℃, and fresh litchi will turn black and taste when placed at 0℃ for one day. Citrus fruits, such as oranges, lemons and oranges. It is easy to penetrate into the pulp at low temperature, and the pulp will be bitter, which is not suitable for refrigerator. Citrus fruits are best stored at room temperature of 15 degrees.
Instant fruits, such as strawberries, bayberry, mulberry, etc. , it is best to buy it immediately. Putting them in the refrigerator will not only affect the taste, but also easily mildew. Apples and watermelons can stay in the refrigerator for a short time to extend the shelf life.
The suitable storage temperature of Chinese cabbage, celery, onion and carrot is about 0℃.
The suitable storage temperature of cucumber, eggplant and tomato is between 7.2 ~ 10℃.
Pumpkin is suitable for storage above 10℃.
After tomatoes are frozen at low temperature, the flesh of tomatoes is blistered, soft and rotten, or cracked, with black spots on the surface, immature and tasteless, and even rotten in severe cases.
Bananas will turn black and rot when stored below 12℃.
Fresh Litchi If Litchi is left at 0℃ for one day, the skin will turn black and the pulp will go bad.
Don't put Chinese medicine 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 and destroy the medicinal properties of the medicinal materials. Therefore, for some precious medicinal materials, such as ginseng, velvet antler, gastrodia elata, codonopsis pilosula and so on. If it needs to be preserved for a long time, you can put it in a clean glass bottle, then add a proper amount of glutinous rice fried to dark yellow with slow fire, and cover the bottle cap.
Fish in the refrigerator should not be stored for too long. The refrigeration temperature of household refrigerators is generally-15℃, and the best refrigerators can only reach -20℃. However, when the storage temperature of aquatic products, especially fish, is lower than -30℃, fish tissues will be dehydrated or undergo other changes. For example, crucian carp will be prone to rancidity, and its meat quality will change and it cannot be eaten. Therefore, fish stored in the refrigerator should not be kept for too long.
Frozen food should not be stored after thawing. Frozen foods bought from the market, such as meat, fish, chickens, ducks, eggs and quick-frozen vegetables, should be processed and eaten as soon as possible once thawed, and should not be stored. If stored for too long, meat, fish, chicken, duck, etc. It will be restored by the vitality of bacteria and enzymes, which will not only rapidly reproduce and decompose protein and cause deterioration, but also produce toxic histamine substances, which will cause food poisoning if people eat it; Frozen vegetables stored for a long time will not only change color, lose nutrition and decrease quality, but also rot easily and become inedible. Frozen meat, frozen fish, frozen chicken and frozen duck, their tissues and cells will be destroyed by the crystallization of water. Once thawed, a large amount of protein will ooze from the damaged tissues and cells and become food for bacteria to multiply. The experiment showed that the fresh mackerel frozen 1 day was stored at 30℃ for 6 hours, and its spoilage rate was faster 1 times than that of fresh fish. After thawing, the number of bacteria increased by about 2 times when the egg yolk was placed at 65438 08℃ for 2 hours, and increased by more than 50 times after 8 hours. Frozen fresh eggs were stored at 0 ~ 65438 05℃ for more than 65438 00 days. Due to the long-term change of cold and hot temperatures, not only the egg membrane becomes loose and the egg white becomes thin, but also the eggs become sticky, yellow, and even moldy and smelly, making them inedible. Frozen vegetables, especially in hot weather, are not suitable for storage, otherwise green leafy vegetables will turn yellow soon and vitamin C will be easily destroyed. When vegetables are stored at 20℃, the decomposition loss of vitamin C is twice that of vegetables stored at 6 ~ 8℃.

Cucumbers and green peppers will be frozen and "injured" if they are kept in the refrigerator for a long time-turning black, soft and stale. Cucumbers also have sticky hairs. Because the temperature of refrigerator storage is generally around 4℃ to 6℃, the suitable storage temperature of cucumber is 10℃ to 12℃, and the suitable storage temperature of green pepper is 7℃ to 8℃. So it shouldn't last long.
Generally speaking, it is best not to store vegetables in the refrigerator for more than 3 days.
