Five common foods without a "shelf life" in your home. How much do you know? Especially the third one, the longer it is stored, the more valuable it is.

Now, not only middle-aged and elderly people, but also many young people have begun to pay attention to the production date of food.

But few people know that the following 5 kinds of food have no "shelf life" and everyone has them at home. It would be a big loss if you throw them away!

Shelf life is not absolute

You should know that the key factors in judging food safety are: shelf life + storage environment.

For example: If the food is sealed and stored in a good environment, it can be eaten even if it is 1-2 days beyond the shelf life. On the contrary, if it is exposed to high temperature or moisture, it is not recommended to eat it even if it is within the shelf life!

These 5 ingredients have no "shelf life"

① Honey

Honey is a nutritious natural food that has both medicinal and food effects. It can nourish nutrition and prevent diseases and improve health.

"Compendium of Materia Medica" describes honey as "harmonying the Ying and Wei, moistening the internal organs, opening up the three burners, and regulating the spleen and stomach."

On the outer packaging of honey in supermarkets and markets, the shelf life is approximately 12 to 24 months. This is because the state stipulates that food must be labeled with a "shelf life".

But from a nutritional point of view, honey has no shelf life.

Sealed honey stored in a cool and dry place will generally not go bad. But there is a prerequisite, the honey cannot be fake honey blended, and it must be mature enough.

Tips

When taking honey, be careful not to use a spoon with water in it. It is normal for white crystals to form when honey is refrigerated. When storing honey, be sure to seal it tightly, avoid light, and prevent it from getting wet!

② Edible salt

Edible salt is the most common condiment in every household. The main component of edible salt is sodium chloride, which is quite stable.

Whether it is well salt or sea salt, they will not expire. Even if they become lumps due to moisture, they are still edible.

Tips

Some table salts that have been added with multiple elements, such as salt from mushrooms, red dates, wolfberries, etc., have a shelf life.

When buying salt with other ingredients, be sure to check the expiration date! However, you can eat salt without any additives.

③ Liquor

The shelf life of beer is generally three months, and it must be consumed on the same day after opening the bottle. If you drink it the next day, the taste will change.

But for high-proof liquor with an alcohol content of more than 50% brewed from pure grains, "the older the liquor, the better it tastes". During the storage process, the microorganisms will continue to ferment, and the taste will become more and more mellow and soft.

Generally speaking, liquor should be stored in a light-proof, well-ventilated place with a relative humidity of around 70% and a temperature between 0 and 20 degrees. Fireworks are strictly prohibited from approaching.

④ Aged vinegar

Any food with the word "陈" in it has been stored for a long time and is more nutritious.

Tips

Once the aged vinegar is opened, it will inevitably be affected by the external temperature, air, and high temperature near the fire, and it will easily deteriorate!

5. Beans

After soybeans are dried, they contain very little water. If they are kept in a dry, cool and ventilated place, they can be stored for a longer time without even losing their nutrients.

However, in reality, dry beans are difficult to preserve for a long time, especially in the hot summer, as they are prone to infestation by insects.

If there is obvious mold or other strange smell on the surface of soybeans, it means that the soybeans have been contaminated with aflatoxin. Do not eat them. It is recommended not to buy beans in large quantities!

Don't drink this kind of food after its expiration date.

It is fresh milk! This kind of food has a very short shelf life. Generally speaking, it is only 7 days or 15 days. Throw it away immediately if it is one day past the expiration date!

What is the shelf life of common foods?

① Overnight dishes

It does not only refer to food that has been left overnight, but also refers to food that has been left for more than 8-10 hours. There is an old saying about leftovers: "It is better to have leftover meat than vegetables."

② Eggs

Eggs do not have a fixed "shelf life" and are greatly affected by temperature and humidity. Generally speaking, 3 to 5 weeks is enough.

When the temperature is between 2 and 5 degrees Celsius, the shelf life of eggs is about 30 days; if stored at room temperature in summer, the shelf life is 7 to 10 days.

Tips

The big head is facing up, and the small head is facing down;

Put the eggs in a sealed bag and place them on an egg rack. Store them in a refrigerator at low temperature to ensure the safety and nutrition of the eggs.

③ Seafood and meat

This must be the category that everyone is most concerned about. They are particularly susceptible to bacterial invasion and must be stored at low temperatures.

If refrigerated, it is best not to exceed 2 to 3 days; if frozen at -18℃, it can be kept for 1 month to half a year.

It is recommended to package the meat according to the amount consumed each time to reduce unnecessary repeated thawing.

④ Cooking oil

Unopened, the "shelf life" of general cooking oil is 18 months. Once opened, the "shelf life" of cooking oil will be greatly shortened, and it is best to consume it within 3 months.
