The shelf life of food is a factor that we often look at when choosing food products. However, some foods can be kept for a long time under the right conditions, and can even be said to "never expire". So, what are these foods that never expire? Let's find out.
1.Salt. Salt is a typical food that never expires. Because of its stability in dry environments, it retains its quality and purity for a long time. Salt is a natural preservative, it can absorb water and preservative, in ancient times, people used salt to preserve food, such as salted vegetables, salted fish, etc. In modern times, we can also add the right amount of salt to food to extend the shelf life of food.
2.Honey. Honey is a natural syrup that inhibits the growth of bacteria due to its high sugar content and acidic environment, and is also a food that never expires. In fact, high-quality honey can last for decades or even centuries.
3.Vinegar. In addition to promoting human digestion, aged vinegar can also improve metabolism. The longer the vinegar is stored, the more delicious it is, and the higher it is! In life, most people think that aged vinegar has a storage time, but in fact, aged vinegar does not have a storage time. The longer a good aged vinegar is stored, the more fragrant and sour it will be.
4.Sugar. Sugar is a natural sweetener that retains its quality for a relatively long period of time. White granulated sugar and brown sugar usually last for a long time and do not spoil during storage. Although a lot of sugar has an expiration date written on the packaging, experts say that sugar only melts, not expires!
5.Wine. The liquor will be stored better and better. In particular, pure cereal wine, which has been left for many years, has a very mellow taste, and the longer it is stored, the more mellow the flavor of the sake becomes. However, not all liquors can be preserved, and most of the ones that can be stored for a long time are pure grain wines, not blended liquors.
6.Tangerine peel. Tangerine peel is an orange peel that has been left for a long time, and the longer it is stored, the higher the value of tangerine peel.
While these foods can be stored for a long time, it doesn't mean they don't have any risks. During the preservation process, these foods may be contaminated or produce harmful substances, so we still need to pay attention to the storage conditions and safety of the food.
In conclusion, foods that "never expire" are not foods that do not have an expiration date, but foods that can be stored for a long time under the right conditions. Understanding the characteristics of these foods and how they are stored can help us better preserve them while keeping our food safe and healthy.
