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.

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.

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.

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.
