Can you eat leftovers frozen for a month, and can you still eat vegetables when they are frozen

It is not recommended to eat leftovers that have been frozen for a month, because they are basically spoiled after a month of freezing.

Leftover vegetables should not be stored in the refrigerator.

Some leftover vegetables, especially the remaining leafy greens, not only destroy their nutritional value, but also produce disease-causing nitrites.

The amount of nitrite in the remaining vegetables will increase with the extension of storage time and the increase of temperature, and if the vegetables are refrigerated in the refrigerator (2-6 degrees Celsius), the relative non-refrigeration of nitrite will increase less. However, there are many nitrates in green leafy vegetables, and even if they are put in the refrigerator and eaten overnight, the nitrites will exceed the standard.

Leftovers can be refrigerated for 2 days.

For the rest of the meat, or fruits and vegetables, use plastic wrap.

Sealed and refrigerated for up to two days. However, it is best to put it in a shallow bowl before putting it in the refrigerator, and wait for the leftovers to cool to room temperature before putting it in the refrigerator, so that the temperature of the food will be more uniform and will not be so easy to spoil.

Leftovers can be left frozen for more than 7 days.

If there are a lot of leftover dishes, it is estimated that you will not be able to eat them in two days, you can use small bowls to divide them, seal them, put them in the refrigerator in turn and freeze them, and take out a small portion each time you eat. Do not take it out repeatedly to heat it up and then return it back to freeze. Food can be contaminated with airborne bacteria when you take it out, so it's best to eat as much as you want, and don't put it back when you take it out.

Although frozen, the shelf life of leftovers.

It will be lengthened, but it will not last forever. It is usually recommended to eat within 1 week, but not more than 2 weeks at most. Even if it does not deteriorate, the longer it is frozen, the lower the nutritional value of the food.

Tips.

1. Leftovers are easy to smell in the refrigerator, so they must be classified and sealed with plastic wrap or plastic wrap or plastic bag. This keeps it clean and prevents cross-contamination of bacteria in the refrigerator.

2. Do not refrigerate food repeatedly, and try not to put the food back in the refrigerator after taking it out.

3. Clean the refrigerator regularly, it is best to clean the refrigerator at least once every three months, defrost if there is frost, remove odor if there is peculiar smell, not only can save electricity but also be more hygienic.

I can't eat this for a month, so hurry up and throw it away, be careful to eat and run loose stomach.

I thought I couldn't eat it, I would get sick.

How can it freeze for a month?

Frozen vegetables cannot be eaten, the main reasons are serious nutrient loss, bad taste, and harmful substances.

1. Serious nutrient loss: If it is lower than 0 °C, the plant tissue of vegetables will be seriously damaged, and vitamins, amino acids and other components will be lost. For example, after tomatoes are frozen at low temperatures, the flesh will be blister-like, the umami will disappear, it will not be easy to cook, and it will accelerate its rancidity and rot.

2. Bad taste: After freezing, vegetables will have a great discount in taste due to the loss of some nutrients, or rancidity and decay after freezing, and even strange tastes such as bitterness and sourness.

Precautions for refrigeration of vegetables.

1. Don't wash first.

In general, vegetables should not be washed before being put in the refrigerator, as an excessively humid environment is a breeding ground for bacteria. Washing vegetables and putting them in the refrigerator is easy to increase the humidity in the refrigerator and create conditions for bacteria to multiply. In addition, fruits and vegetables usually have a layer of wax on the surface to protect them from microorganisms, and washing them will destroy them, making it easier for bacteria to enter the inside of fruits and vegetables.

2. Put it in a plastic bag.

Put it in a film bag or food bag, don't seal it too hard, leave some breathing openings, so that it can breathe, if it can produce convection is the best, and a few more small openings can be used to achieve convection. This keeps the moisture inside the leafy vegetables from evaporating so quickly and getting respiration.

3. Do not put it directly in the refrigerator.

It is best not to put vegetables bought from the market directly in the refrigerator. This is because in order to make the green leafy vegetables look better and not easy to wilt, merchants will spray a little water on them every once in a while. When you buy it and store it at home, you should first dry the water droplets on the surface of the leafy greens, then wrap the vegetables in a clean paper towel, and then put them in a bag and put them in the refrigerator for storage.

Because the paper will absorb some water, it will not allow the vegetables to soak in the wet water, so it will not perish. This method is suitable for leafy greens such as rape, lettuce, spinach, bok choy, amaranth, coriander, leeks, chives, water spinach and lettuce.

4. Don't use plastic bags.

Wrap the vegetables directly in a plastic bag and store them in the refrigerator, and when you take them out, you will feel that the plastic bag is wet and has a lot of moisture. This is due to the fact that the vegetables are stuffed in plastic bags, which causes the surrounding humidity to become high. This makes it easy for bacteria to grow, causing vegetables to spoil.

Poultry meat such as chickens and ducks should be cooked at a temperature of at least 74 degrees Celsius.

All meat should be kept cooking at the specified temperature for at least 3 minutes to achieve the purpose of sterilization. To facilitate testing, these agencies recommend purchasing a household food thermometer.

Leftovers should be kept below 4 degrees Celsius. In order to cool the leftovers quickly, you can use the method of dividing the dishes and large pieces of food into small boxes and putting them in the refrigerator.

If the dish is frostbitten for a short period of time, there is no spoilage, and the frostbite is not severe, it can usually be eaten. However, if the food is more severely frozen and has been for a long time, it is not recommended to eat it again at this time.

It is recommended to eat fresh vegetables as much as possible, and dispose of them in time after they are frozen.

Food should be purchased on demand, it is not recommended to stock up on large quantities of food at one time, and it is also recommended to store it at a suitable temperature to avoid frostbite.

Precautions. Freezing vegetables requires a certain amount of skill, and it cannot be directly thrown in the refrigerator like meat, and needs to be further processed before freezing. Wash the vegetables first, then cut them into sections or cut them into the way they need to cook, then dry them in a cool place, if you are too troublesome, directly use kitchen paper to absorb the water, and then put them in a plastic bag and put them in the refrigerator to freeze.

This can be stored for at least 7 days, note: must be dried to put it in the refrigerator to freeze, when cooking, just take it out and throw it into the pot to fry, no need to thaw.

You can eat it without spoiling.

Leftovers need to be cooled before putting them in the refrigerator. This is because when hot food suddenly enters a cold environment, the food center is prone to qualitative changes, and the hot air brought in by the food will cause the condensation of water vapor, which will promote the growth of mold, which will lead to the mold of the whole food in the refrigerator.

Meat dishes are easy to grow bacteria for 2 hours. Harmful bacteria in the air will attach to some high-protein, high-fat leftovers within 2 hours to multiply, protein and fat under the action of bacteria, most of them will produce harmful substances, such as hydrogen sulfide, amines, phenols, etc., these substances are harmful to the human body. Therefore, leftovers are placed in the refrigerator within two hours of cooking and served in a shallow container for easy cooling.

Can you still eat the food when it is frozen?Vegetables can be eaten when frozen, such as frozen eggplant, frozen beans are very delicious, stewed cabbage is used to stew potatoes, stewed tofu are very delicious, and there are many dishes that can be eaten frozen, for example, Po Ding is also very delicious to thaw it in winter to make a boiled mix.

Harmful substances are produced, and some vegetables, once frozen, may also produce harmful substances to the human body.
