Honey is weakly acidic, and it is easy to cause oxidation reaction when it comes into contact with metals. 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 should not be stored in metal containers, but in nonmetallic containers, such as ceramics, glass bottles, non-toxic plastic barrels, etc.

2, sealed preservation

Generally, honey eaten at home is bottled. After eating, pour out a little and seal it with a lid. This cover has no effective sealing measures, and air and bacteria can easily enter. So when choosing honey, you can choose a small jar and eat it in a few days. If you are unlucky enough to buy a big can, buy a roll of plastic wrap, cover it every time you eat it, and then wrap the bottle mouth with plastic wrap.

Step 3 separate from smelly food

Honey should also pay attention to odor prevention, moisture prevention, fermentation prevention and pollution prevention during storage. In order to avoid odor and pollution, it is not allowed to be corroded or unsanitary with odorous items.

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. It can be stored in a cool place at room temperature. Glucose and fructose in honey can absorb water in the air, which makes it thinner and easy to ferment and deteriorate. So honey should be kept in a dry place, covered and preserved. In addition, honey contains a variety of enzymes and vitamins, which will decompose when exposed to light, so it is best to keep it away from light.

5, cold water preservation

Another preservation method is cold water preservation. Bottled honey should be packed in bags and sealed tightly to avoid water leakage. Then fill a basin of suitable size 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 many fresh-keeping effects and honey will not crystallize. This method is used to preserve fresh milk in rural cattle farms.
