These 8 foods or have no 'shelf life'? It can be stored for a long time or can be eaten, it is recommended not to waste it
With the popularization of medical knowledge, if everyone's awareness is getting higher and higher, they will not eat the moldy food in their lives in the past, for fear of affecting their health.
However, when we go to the supermarket, we are used to buying large quantities of food at one time and placing it for a while. Many people choose to throw them away because they worry that expired food will become moldy and spoiled, endangering the body and increasing the burden on the body.
Not only do the vegetables in our lives expire, just like canned meat and bacon, they go bad over long periods of storage. Health awareness is getting stronger and stronger, and there is no sympathy for expired food.
It will taste better and be safer to use only if it is used within the shelf life of the food, but some foods have no shelf life and the longer they sit. The better the taste, the possibly increased nutritional value.
01
Can I eat food that is approaching its expiration date?
When you visit a supermarket, you can see a lot of food going into action. Most of the food is about to expire in about a month. The price is attractive, not even a third of the original price.
In order to be able to deal with these fast-expiring foods, merchants will choose to sell them at low prices, but foreign supermarkets will sell foods that are close to expired at low prices, or directly transfer them to secondary coupon agencies. This is also to allow low-income people to have the most basic life security.
In fact, food that is close to expiration can be put in and eaten. After all, the food has not reached the shelf life, and the quality and safety can also be guaranteed. As long as the food is within the shelf life, it can be eaten with confidence.
However, I would like to remind you that not all foods are safe during their shelf life. When some people shop at the supermarket, they find that the food spoils after being opened before the expiration date. Is anyone changing the production date?
In fact, malls don't do that. Food doesn't suddenly spoil at the expiration date, but after production it can grow bacteria or food additives that react during the packaging process.
Second, imperfect transport conditions or prolonged storage may lead to food spoilage. When shopping, we not only look at the shelf life, but also look at the color, taste, hardness, etc. of the food.
To sum up, pre-produced food cannot be eaten within the shelf life, but there will be some unsafe factors in general. I hope you should choose fresh food purchased from regular supermarkets, which is rich in taste and guaranteed in nutrition.
It is worth reminding that some foods are very common in life. While the shelf life appears to be short, there is no actual shelf life. They can also be used for a long time. Don't waste them.
02
These 8 kinds of food still have no shelf life? For long-term storage or consumption, it is recommended not to waste.
- Mature vinegar
The national food label management regulations require that food labels should clearly indicate the production date and shelf life of the food, but there are four kinds of foods that cannot be marked with the shelf life.
This food is alcohol, vinegar, salt and solid white sugar, and contains more than 10% ethanol.
It is normal for vinegar without an expiration date in life, but this does not mean that vinegar can be stored indefinitely, and mature vinegar with an expiration date will strictly abide by the production date label.
In order to ensure the safety of food, the manufacturer will also calculate the shelf life before leaving the factory, and the old vinegar without production date and shelf life.
The acidity is above 4.5 degrees. This kind of old vinegar does not add any preservatives, and it can also achieve the phenomenon that it is not bad for a long time. Under normal circumstances, there is no need to mark the shelf life.
In theory, long-term storage is just to store mature vinegar in daily life, which is different from the storage conditions in vinegar factories. Once opened, edible vinegar is susceptible to bacteria and temperature that can cause food to spoil.
Even old vinegar with no shelf life will have some sour taste when it is found that the vinegar smell is abnormal, and it is recommended not to use it again.
- Pu'er tea
It is said that the older the Pu-erh tea, the more fragrant it is. After the best trial period, there will also be some deterioration on one side of the tea leaves. Although the color of the tea varies in taste, it is also safe to use.
The term shelf life is not the only standard for deterioration of all food products. Generally speaking, the food will not mold or spoil during the shelf life.
It is worth reminding that the taste, smell and appearance of food can also change if the storage environment is not up to the requirements. Food spoilage may occur if the food is not past its expiration date.
The same goes for Pu-erh tea. It cannot be said that it can be stored indefinitely without a shelf life. It also depends on whether the storage conditions are in a cool, ventilated and dry place. Otherwise, there will be some spoilage even if there is no shelf life.
When the tea leaves go bad, the color and smell of the tea leaves will become lighter, the color of the tea leaves will change a little, and it will even give off a musty smell. The use of this tea is not recommended to avoid burdening the liver with excretion.
- Dried fungus
Dried fungus is a dry product, which has been completely dried without breeding bacteria and other toxins. As long as it is stored, it will not expire.
However, I would like to remind you that dried fungus can easily attract small insects. When storing, try to put it in a ventilated place. If it is moldy, it is recommended not to eat or soaked black fungus. Try to consume within 24 hours of the shelf life.
- Honey
In fact, pure natural honey will not expire, because honey itself has strong antibacterial and antioxidant capabilities, and is a natural non-deteriorating food.
It has been found that in the Egyptian pyramids, honey stored more than 3,000 years ago has not deteriorated after expert identification.
Honey does not spoil and expire, mainly because of their high purity. The crown honey purchased in life is processed and is not of high purity. There will be some deterioration during the shelf life.
Honey has an expiration date. The country began to implement honey production standards in 2006, requiring companies to indicate a two-year shelf life in the honey production process. Most businesses mark two years, some honey manufacturers will mark six to 18 months.
May wish to observe carefully the crystallization of honey, but the state is different, it will not affect the texture of honey, it is better to smell the taste of honey.
- Edible salt
As a mineral element on earth, sodium chloride has a poor shelf life. For the past six months, table salt has been used to ensure the freshness of other vegetables, remove surface moisture, and extend shelf life.
Table salt can be stored for a long time without a shelf life. If you buy iodized salt, the shelf life will also be shortened. The amount of table salt a household buys should be well controlled. Don't store too much at once. At the same time, salt intake should be kept below 6 grams per day.
- Soy sauce
Opened soy sauce bottles can also be stored for more than three years. Depending on the processing method, quality and storage conditions of soy sauce, the shelf life of the container will be longer.
High-quality soy sauce takes months or even two years to produce through natural fermentation. Only this soy sauce will last more than three years. When buying soy sauce, be sure to pay attention to whether chemicals or additives have been added.
- White sugar
The raw material of white sugar comes from the shelf life of sugar cane or beet sugar, which is relatively long. If exposed to the air for a long time, it will easily absorb moisture and turn into a hard lump, but it will not affect the taste.
Compared with other foods, white sugar generally does not deteriorate. If the color of sugar is found to change or the taste becomes weak, it will not affect our normal use.
- High concentration liquor.
Especially male friends, they habitually drink some liquor every night after get off work, and the company also drinks. Many people know about wine storage. The longer the time, the more mellow the taste.
Alcohol above ten degrees has almost no alcoholic substances, so it will not deteriorate like white wine, and it can be drunk even after the expiration date.
Although alcohol has no shelf life, for the sake of safety, it is not recommended to drink for a long time, so as not to increase the burden on the liver and cause physical discomfort.
It is worth reminding that food beyond the shelf life will not affect its own health. Some foods don't go bad for a long time. However, some foods may spoil after a day or two of storage. Whether the food is edible should be judged according to the actual situation.
