Can you eat oranges when they re frozen, and can you eat oranges when they re frozen?

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.

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.

Frozen oranges are not recommended to eat, if they are frozen for a short period of time, they need to be thawed and drunk as soon as possible, and the thawed oranges cannot be frozen or refrigerated again, otherwise the oranges will accelerate their deterioration. If it has been frozen for more than three or four days, or even two weeks, don't eat it.

Oranges are rich in vitamins C and P, which can increase the body's immunity, increase the elasticity of capillaries, and reduce blood cholesterol. People with hyperlipidemia, high blood pressure, and arteriosclerosis often eat oranges. The cellulose and pectin substances contained in oranges can promote intestinal peristalsis, which is conducive to intestinal laxation and elimination of harmful substances from the body.

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.

Oranges can still be eaten even if they are frozen. Although oranges are southern fruits, if they cannot be eaten in a short time, they should also be refrigerated. 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 2-3 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, do not store for more than 2 weeks.

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.
