In our daily lives, we often rely on the expiration date on food packaging to decide whether to consume a certain food. Once they see that the expiration date is approaching or has passed, many people will not hesitate to throw it away. However, what you may not know is that there are 7 types of food that have almost no shelf life, and as long as they are stored properly, they can be stored for a long time and don't throw them away in vain!
1. Honey.
Pure honey can be said to be a very magical ingredient. The main components of honey are glucose and fructose, and the water content is minimal. Due to its high concentration of sugar and low moisture content, it is difficult for bacteria and microorganisms to survive. When well sealed, honey can be stored for a long time without spoiling. Archaeologists have found thousands of years of honey in tombs in ancient Egypt that has not deteriorated. Of course, when storing honey, it is necessary to pay attention to sealing it to avoid moisture entering, and at the same time keep it in a cool and dry place to prevent high temperature from affecting its quality. If the honey crystallizes, don't worry, it's a normal physical change, not a spoilage. The honey bottle can be soaked in warm water to bring it back to its liquid state.
2. Edible salt.
Salt is an indispensable condiment in our lives. Whether it is well salt mined in a well or sea salt taken from the sea, the chemical properties are very stable. Pure table salt, which has no additives, can be stored indefinitely. However, if it is not stored properly, the salt will become agglomerated by moisture. To prevent this from happening, salt should be stored in a dry, cool place. In ancient times, salt was also used as currency and as an exchange item. Nowadays, we can buy more salt and store it without worrying about expiration. However, if iodized salt or table salt containing other trace elements and additives is used, there may be certain shelf life requirements due to the stability of these added ingredients.
3. Dried beans.
Various dried legumes, such as soybeans, black beans, mung beans, etc., are also one of the ingredients that do not have an expiration date. These dried beans can be stored for a long time as long as they are kept dry and free from moisture and insect infestation. Dried beans are rich in protein, dietary fiber, vitamins, and minerals, making them a very healthy ingredient. It can be used to cook porridge, make soy milk, cook soup, etc. To better preserve dried beans, they can be placed in an airtight container or packed in a plastic bag and refrigerated in the refrigerator. This prevents the beans from getting damp and insects, and prolongs their shelf life.
Fourth, tangerine peel.
Tangerine peel is made of dried orange peel, as a medicinal and edible ingredient, it has the effect of strengthening the spleen and appetizing. Tangerine peel, like other medicinal herbs, will not expire as long as it is stored for as long as it does not attract insects. Over time, the therapeutic effect of tangerine peel will be stronger. But pay attention to the method when storing it to ensure its quality.
5. Liquor.
Baijiu is also an ingredient that does not have a strict expiration date. The main components of liquor are alcohol and water, and alcohol has the effect of sterilization and disinfection, so that liquor can be stored for a long time when it is well sealed. Moreover, the longer some high-quality liquor is stored, the more mellow the taste will be. This is because during the storage process of liquor, a series of chemical reactions will occur, which makes the aroma substances in the liquor more abundant. However, it is necessary to pay attention to the storage method of liquor, which should be sealed well and avoid direct sunlight and high temperature environments. At the same time, the storage time of different types of liquor will also vary, and generally speaking, high-strength liquor is more suitable for long-term storage than low-alcohol liquor. But for blended wines, they need to be consumed within the expiration date.
6. Aged vinegar.
Aged vinegar with an acidity of more than 4.5g/dL can be exempted from the standard shelf life, because the pH value is too low to inhibit the growth of microorganisms and can achieve long-term storage. However, once opened, aged vinegar is susceptible to deterioration due to the influence of external temperature, air, etc. Therefore, it should be sealed and kept in a cool and dark place, but this does not mean that it can be stored forever, if the liquid becomes cloudy, there is sediment or the taste is abnormal, it means that the vinegar has gone bad.
7. Pu'er tea.
The types of tea are quite rich, but when it comes to the characteristics of "the older the more fragrant", Pu'er tea is the best choice. Pu-erh tea is very different from other teas, and its value generally increases with the time of storage. Those Pu'er teas that have gone through more than ten or even dozens of years of aging process are not only incredibly expensive, but also a treasure that tea lovers are vying for. The aging of Pu-erh tea is a natural fermentation process, in which the flavor of the tea leaves becomes more mellow and the taste is softer. However, when collecting Pu'er tea, you must pay attention to the work of moisture and mildew prevention, after all, the humid environment will have a negative impact on the quality of Pu'er tea.
