Storage of honey
Correct storage of honey is an important link to ensure its quality, so in the process of storage, attention should be paid to the following problems:
1. Honey is a kind of acidic viscous liquid, which can corrode metals such as zinc, iron, aluminum and plastic buckets. in order to avoid honey pollution, metal containers and plastic buckets without food paint can not be used to store honey, but use glass bottles, porcelain jars and other containers to store honey.
2. Honey has the characteristics of strong water absorption and peculiar smell, so it should be sealed and stored to avoid water absorption and fermentation, and it is difficult to eat.
3. Containers filled with honey should be washed with running water before loading, and then dried and then loaded with honey.
4. Honey should be stored in IO ℃ ~ 20 ℃. Keep the storage room dry, ventilated, cool and without direct sunlight. If possible, keep honey at a low temperature of 5 ℃ ~ 10 ℃. Because the growth of yeast cells stops when it is less than 10 ℃, fermentation can be stopped, so it can effectively prevent the fermentation of honey and some changes caused by storage. Do not store honey with volatile odors, such as soap, gasoline, etc., so as not to smell.
