Can you still eat oranges when they are frozen in winter, and can you still eat them after they are

Whether oranges can be eaten when frozen hard still needs to be judged according to the specific situation. If there is no frost damage, it can generally be eaten, but the taste may change to a certain extent; If there is already spoilage, it is usually not edible.

1. Edible: If oranges are frozen in the refrigerator or placed in a relatively low temperature environment in winter, they may cause oranges to be frozen hard. If the oranges do not rot or deteriorate after thawing, they can generally continue to be eaten, but the texture and taste of the oranges may change.

2. Can't eat: After the orange is frozen hard, it may lead to excessive water loss. In addition, if it is frozen for a long time, bacteria and mold may grow, and after thawing, it will become soft and deteriorate.

In this case, the orange is frozen and hard and cannot be eaten, otherwise it will affect your health and may lead to food poisoning in severe cases.

Tangerines are a relatively common fruit in daily life, and it is generally recommended to eat fresh oranges for a better taste. Tangerines contain certain mineral elements, such as calcium, iron, phosphorus, etc., and the vitamin content is also relatively high, such as vitamin C, vitamin B1, etc., and also contains citric acid, malic acid and other organic acids, which can provide some nutrients for the human body.

Frozen oranges are edible, but it depends on whether they are good oranges before freezing, and if they are good oranges that have not rotted and deteriorated, then they can be eaten after they are frozen. In particular, the frozen oranges on ice are delicious, and they are very cool. However, if the orange has become bitter or has a strange taste, then do not eat it, it may cause food poisoning.

Although oranges are southern fruits, it is best to refrigerate them if they cannot be eaten in a short time. Citrus fruits such as kumquats, mandarins, sugar oranges, and navel oranges can all be stored in the refrigerator. The temperature of the refrigerator is mostly about 4, at this temperature, the respiration of oranges is weaker, so the consumption of nutrients is smaller, and oranges will not be frostbitten, and will not produce harmful substances to cause food poisoning.

In addition, the high humidity in the refrigerator can prevent the oranges from losing too much water and deteriorating the taste.

Under normal circumstances, in Sichuan, Chongqing and other places close to the production area, citrus can be stored in the refrigerator for 2 to 3 months, while oranges transported to the north can be stored in the refrigerator for about 1 month due to the inevitable bumps during transportation. If the oranges are stored indoors, the temperature is too high and the air is dry, the oranges are not only easy to lose water, but also more likely to rot, in this case, it is best not to store for more than 2 weeks.

In winter, oranges can be eaten even when they are frozen, as long as the taste remains the same.

If citrus is frozen in ice, its protoplasm will become dehydrated, and the protein will coagulate, making it much less antibacterial.

Therefore, once citrus is frozen, some bacteria, especially mold and other spoilage bacteria, will invade the fruit extract, making the bitter taste of citrus aggravated and the nutritional value reduced. Note that you should also pay attention to the storage of oranges at room temperature in winter, the temperature is too low, and the oranges are frozen for too long, be careful whether they are bitter, and do not eat them if they are bitter.

When oranges are frozen, they are not only nutritious, but also too unpalatable and a little bitter, so it's best not to eat them.

Oranges can be eaten when they are frozen, but the taste is not very good, so it is recommended to use frozen oranges and other fruits together to make soup and drink.

Oranges can't be eaten when frozen, but they can still be eaten when thawed with warm water. But if it's hard to freeze, throw it away, and the orange has already turned sour.

Frozen fruits can be eaten.

The fruit itself is cold, frozen fruit is even colder, the fruit is stored at room temperature, vitamins are easy to lose, low temperature preservation can not only slow down the reproduction of microorganisms, but also inhibit the decomposition of some enzymes, slow down the speed of food deterioration. Therefore, frozen fruit will not affect its nutritional value, as early as the Liao Dynasty, the Khitan ethnic group has formed the custom of eating frozen pears and frozen pestles.

According to doctors, try not to eat fruits and vegetables that have been frozen to death. Fresh fruits and vegetables should not be stored in the refrigerator for more than 3 days, and all fruits and vegetables that look yellow and black and have rotted should not be eaten again. Nitrite will be produced when the vegetables are frozen, and excessive consumption will cause symptoms such as headache, dizziness, nausea, vomiting and redressing.

Dangers of frozen fruits and vegetables:

1. The taste changes.

Now vegetables and fruits ** are more sufficient, or be cautious of eating frozen fruits and vegetables, "the taste of frozen vegetables and fruits will change, very unpalatable" oranges, oranges, cucumbers, etc. are easy to be frozen fruits and vegetables, take oranges as an example, the skin of the oil seeps into the pulp, and the taste will be bitter.

2. Produce harmful substances.

There are also some fruits and vegetables, once they are frozen, they may also produce substances that are harmful to the human body. For example, cabbage, beans, etc. New experimental studies have found that cabbage will contain higher nitrite and nitrate after being frozen, with nitrite content exceeding 25 milligrams per 100 grams of frozen cabbage, and people may experience symptoms such as dizziness, nausea and vomiting after eating.

Experts point out that in most people's perception, refrigeration and cryopreservation can keep food fresh and avoid loss of nutrients. Actually, this is a misconception. Scientific experiments have proved that different types of food have different temperature requirements for "freshness".

Most fruits and vegetables are stored above zero temperature. Most vegetables and fruits are best stored at temperatures above freezing. Such as cucumbers, eggplants, tomatoes, bell peppers, etc., the suitable storage temperature is between -2 10.

The minimum suitable temperature for this kind of fruit and vegetable is -2, so it can be put in the refrigerator for refrigeration, but it should not be stored for a long time, only suitable for two or three days. Fruits and vegetables with a suitable temperature of 0 7 can be left for a longer time. Bananas, lemons, pumpkins, etc. should be stored at a temperature of 13 15.

The suitable storage temperature of this kind of fruits and vegetables is more than 10, which exceeds the maximum temperature of the refrigerator, and should not be stored in the refrigerator, otherwise it will be "cold damage" and destroy its nutrients.

Some fruits and vegetables are suitable for zero-degree preservation. Some vegetables should be stored at about 0, such as cabbage, lettuce, spinach, celery, cauliflower, onions, cabbage, carrots, peaches, grapes, apples, strawberries, etc. These fruits and vegetables can be safely refrigerated and left for a few more days.
