These foods do not have a "shelf life", don't throw it away stupidly!

When you buy food, you often look at the "shelf life". After all, the "shelf life" is related to the quality and safety of food. There are also many people who like to buy a lot when buying food, but they ca n’t eat it often. After being stored for a period of time, they find it directly when they expire.

But do you know? Some foods do not have a "shelf life". Even if it is stored for a long time, you can continue to eat it. I advise you not to throw it away stupidly! Which foods have no "shelf life"? Xiaobian will take you to find out!

1

Honey

From the perspective of nutrition, the real honey does not have a "shelf life", and even if it is stored for a long time, it is not prone to moldy and deteriorating. Although honey sold on the market is marked with a clear "shelf life", because the state stipulates that food must indicate that food has a shelf life, and the "shelf life" of honey is mostly two years. Honey contains 0.1%to 0.4%of bacteriostatin, almost no water, and the bacteria exist in the living environment are almost difficult to breed. The sealing honey is placed in a cool and dry place, and generally does not deteriorate.

The preserved honey itself does not have a "shelf life", but there is a premise that honey cannot be blended fake honey, and it must be mature enough.

2

salt

During the production process, the edible salt will appear sodium chloride and chemicals, so that the "shelf life" can be effectively maintained.

Therefore, no matter what salt is, it will generally not expire, but the problem of humidity blocks due to improper storage can be continued.

3

Solid sugar

The solid sugar structure has less water and strong osmotic pressure, which is not conducive to the growth of microorganisms, and it is not easy to pollute. Therefore, it is not easy to deteriorate and there is no "shelf life".

However, sugar is easy to absorb moisture. If it is not placed properly, the nature of the nature will be contaminated by microorganisms. If it is placed in a cool environment to avoid high temperature and high humidity environment, it can generally be stored for a long time. It is recommended to store sugar as much as possible in the sealed container.

4

High liquor

Highly distilled liquor, especially the high -level liquor brewed in grain, there is no "shelf life".

As the saying goes, "wine is the incense of Chen". The white wine brewed in pure food will continue to ferment during the storage process, and the taste will become more and more soft.

5

Old vinegar

According to national regulations, old vinegar with acidity above 4.5 g/dl can be exempted from the standard period. To this extent, the pH value can be significantly inhibited to inhibit the growth of microorganisms, prevent bacteria pollution, and achieve the role of long -term preservation. Essence

However, once the vinegar is opened, it will inevitably be affected by the temperature and air of the outside world. For example, many families generally put the vinegar next to the fire. At this time, the temperature is relatively high, and the vinegar is easily exposed to the air. Expired and deteriorated.

It is recommended to seal the vinegar densely in a cool and avoid light, but this does not mean that it can be kept permanently. If the vinegar liquid becomes turbid, has a precipitation or abnormal taste, it means that the vinegar has deteriorated.

6

Dried soybean

After the soybeans are dried, there is very little water contained in it. If it is stored in dry, cool, and ventilated places, it can be stored longer.

However, if the surface of the soybeans has obvious mildew, and with mold or other odors, it means that the soybeans have been stained with olexo toxin. It is recommended not to eat it anymore.

The "shelf life" of common foods in life

1. Egg

There is no fixed "shelf life", and there are generally no problems in 3 to 5 weeks. Eggs are best preserved in the refrigerator. When the room temperature is stored, the quality of the egg decreases much faster than that in the refrigerator. It is best to eat it as soon as possible.

Second, meat

Fresh meat such as fish, beef, pork, poultry, etc., the refrigerated time is best not to exceed 2 days. After buying the meat home, if it is not frozen, it should be cooked as soon as possible, and the cooked meat refrigerates longer.

Three, rice noodles

The "shelf life" of rice noodles is 6 months to 12 months under normal temperature. If it is in the north, as long as it is not placed in a high temperature and humid place, it can be extended to 24 months when the storage conditions are normal.

Fourth, bread and pastry

Bakery and pastry such as bulk foods in winter are generally 7 days, spring and autumn are 3 to 5 days, and summer is only 1 to 2 days. Because such foods are rich in moisture, if they are not stored properly, bread and pastry are likely to be moldy the next day and cannot continue to eat.

Five, edible oil

In the state of unknown, the "shelf life" of general edible oil is 18 months. Once the seal is opened, the "shelf life" of edible oil will be shortened. It is best to eat within 3 months, and it is best to avoid light.

Although there is a "shelf life", some foods may be broken in advance for improper storage. If it is not stored properly, when eating these foods, it is found that there are moldy, sticky, soft or hard texture, and suffering, acid, and odor. Do not eat it even if you do n’t expire.
