In our cognition, it seems that any item has an expiration date, especially food, its expiration date is particularly important, once the expiration date has passed, we will be considered to have spoiled and spoiled, and can no longer be eaten. For such food, we usually choose to throw it away. But in fact, the five common foods in daily life do not have a strict expiration date, and some will even become more precious over time, so don't throw it away next time when it expires. So what are the five types of food? Let's find out!
One: liquor.
For some friends who love to drink liquor, it is essential to have some liquor at home, not only can you have a drink in your spare time, but also have guests visiting at home, and it is indispensable to use liquor to entertain. However, the liquor we buy back will be clearly marked with the expiration date on the bottle. When the expiration date is reached, if we don't finish it, we will choose to discard it for the sake of our health. But you know what? That kind of high liquor, that is, liquor with an alcohol content of more than 41 degrees, due to its high alcohol content, has a bactericidal effect, can effectively inhibit the growth of microorganisms, it can be stored for a long time, and there is no expiration date. Especially the kind of high-grade liquor above 50 degrees brewed from pure grains, it also becomes more fragrant the older it ages. However, we should also pay attention to the good sealing when storing, avoiding direct sunlight and high temperature environments.
Two: table salt.
Edible salt is the first of all kinds of flavors, and it is a must-have condiment for every family. Although the shelf life of 2~3 years is indicated on the packaging of table salt, in fact, salt will not expire no matter how long it is stored. The main component of table salt is sodium chloride, a compound that is very stable in the natural environment and does not deteriorate easily. Even if it is stored for a long time, as long as it is kept dry and free from contamination, its quality will not change significantly, and it is still safe to continue eating. Not only that, table salt also has a good preservative effect, usually when we marinate food, put more salt, but also prolong the storage time. However, some salts with added elements, such as mushrooms, red dates, wolfberries, etc., may gradually reduce their activity or change over time, so these salts need to be consumed within the specified shelf life to avoid spoilage.
Three: Honey.
A few days ago, when I was tidying up my home, I was cleaning up some items that had been stored at home for a long time and had expired, and I accidentally rummaged through a bottle of honey in the cabinet. This bottle of honey is a few years old, and it is still authentic honey that I bought from the countryside a few years ago. Since it had been left for several years, although I was reluctant, I thought it was expired, so I was ready to throw it in the trash. When my husband saw it, he quickly took it from my hand and said that the honey would not expire, there was almost no water in it, and the sugar content was very high, forming a natural antiseptic environment, even if bacteria invaded, it was difficult to breed. I've also seen the news before, and when honey was found more than 5,000 years ago, it was still good. However, it should be noted that if it is some honey with other substances added, then you need to pay attention to its shelf life.
Four: vinegar.
According to national regulations, aged vinegar with an acidity of more than 4.5g/dL can be exempted from the "shelf life". In other words, this aged vinegar can be stored for a long time. Because its pH is too low, it can effectively inhibit the growth of microorganisms, so that it can be stored for a long time without spoiling. However, it should be noted that once the aged vinegar is opened, it will inevitably be affected by the outside temperature, air, and high temperature next to the fire, so that it is easy to deteriorate! Therefore, unopened aged vinegar can be stored for a long time, but it should also be kept in a cool and dark place. And if the aged vinegar has been opened, it is recommended to consume it in a short time.
Five: Pu'er tea.
Tea is also a common item in our homes, but did you know? Pu-erh tea is also an item that does not expire, and the quality of Pu-erh tea will gradually improve with the passage of time. In fact, it is because during the storage process of Pu'er tea, the components such as theophylline and tea polyphenols will continue to differentiate and transform, making the tea more mild. At the same time, the aroma of Pu-erh tea will also change, and aged Pu-erh tea will exude a unique aged fragrance that will make people have an endless aftertaste. Therefore, if we find Pu'er tea that has been sitting for a long time in our home, we must not throw it away because it has expired, the older it is, the more valuable it is.
