1, honey refrigerated shelf life of 18 ~ 24 months, do not recommend freezing to save, the freezer on the honey of the nutrient composition of the impact is relatively large. Honey preservation is recommended to be placed in the refrigerator freezer area, the refrigerator freezer area of the temperature of 4 ~ 6 degrees Celsius, can reduce bacteria and other microorganisms breeding, can be retained to a certain extent in the honey of the nutrients, so as to maintain the taste of food, and at room temperature, the temperature changes, and higher temperatures, easy to breed bacteria and other harmful substances, and may be odor, decay and other deterioration of the situation.

2, honey is honey bees from the flowers of flowering plants in the flower nectar in the hive after the full brewing of natural sweet substances. The odor is fresh and strong, and the taste is pure and sweet.

3. Bees take nectar or secretion with water content of about 75% from the flowers of plants, deposit it into their second stomach, and then under the action of many kinds of transformations in the bees' body, the transformed nectar or secretion will be stored in the hive hole by worker bees and sealed with beeswax. After about 15 days of repeated brewing, will be a variety of vitamins, minerals and amino acids enriched to a certain value, at the same time the nectar in the polysaccharide into the human body can be directly absorbed by the monosaccharide glucose, fructose. And the nectar or secretion with less than 23% water content is honey.

4, honey is a supersaturated solution of sugar, low temperature will produce crystallization, will produce crystallization of glucose, does not produce crystallization of part of the main fructose.
