Honey is weakly acidic, and when it comes into contact with metals, it is easy to cause oxidation reaction, and metal ions such as iron, lead and zinc are precipitated, which makes honey discolored and black, and its nutritional value will also be destroyed. Some people will have poisoning symptoms such as nausea and vomiting after eating this honey. Therefore, honey can't be stored in metal containers, but in non-metal containers, such as ceramics, glass bottles and non-toxic plastic barrels.

2, sealed preservation

Generally, honey eaten at home is bottled, a little is poured out after eating, and then sealed with a lid. This lid has no effective sealing measures, and air and bacteria are easy to enter. Therefore, when choosing honey, you can choose small cans and eat them in a few days. If you are unfortunate enough to buy a large can, buy a roll of plastic wrap, cover it every time you finish eating, and then wrap the bottle mouth with plastic wrap.

3. Separate from smelly food

Honey should also be protected from odor, dampness, fermentation and pollution during storage. In order to avoid odor and pollution, it shall not be stored with odorous articles (such as gasoline, alcohol, garlic, etc.), corrosive articles (such as fertilizers, pesticides, lime, alkali, nitrate, etc.) or unsanitary articles (such as waste products and livestock products).

4. Storage environment

Honey should be kept in a low temperature and dark place. In fact, honey doesn't have to be kept in the refrigerator, just keep it cool and away from light at room temperature. Glucose and fructose in honey can absorb moisture in the air, and the result becomes thin and easy to ferment and deteriorate. Therefore, honey should be kept in a dry place and covered for preservation. In addition, honey contains a variety of enzymes and vitamins, which will decompose when exposed to light, so it is best to keep them away from light.

5, cold water preservation

Another preservation method is cold water preservation. Bottled honey is packed in a bag, and the seal should be tight so as not to leak water. Then use a basin of suitable size to fill it with water and put it in a cool place, and then put honey in it. If your home is in the countryside and there is a well, you can put honey in the well, which has a lot of preservation effects and honey will not crystallize. This method is used to preserve fresh milk in rural cattle farms.

Extended data:

Pure natural honey with high concentration can be stored at room temperature, even in hot summer, but for those honey with high moisture and immature honey, the temperature is high in summer, so if there is a refrigerator, you must put it in the refrigerator, but the temperature should not be too low, just store it above 0 degrees, and put it in the fresh-keeping layer. When honey is put into the refrigerator, it will crystallize.

Honey will crystallize below 14℃, which is a physical change, not a chemical change, so the composition of honey itself has not changed, just like the chemical formula is H2O after water freezes. As for some people's reaction to the poor taste of honey after crystallization, this is "carrots and vegetables, each with his own love", and I like to eat honey after crystallization.

Note: It is not necessary to put honey in the refrigerator, but only for honey with high concentration and good quality, it should be stored in a cool and dark place at room temperature. Honey with high moisture content must be put in the refrigerator when it is hot in summer.
