Honey is fully brewed by bees collecting the juice secreted by the nectaries of plants. It is produced in most areas of China. It is better if it is as thick as gelatin, sweet and pure in taste, clean and free of impurities, and does not ferment. The main component of honey is sugar, of which 60% to 80% is glucose and fructose that are easily absorbed by the human body. It is mainly used as a nutritional tonic, medicinal and processed candied food and for brewing honey wine. It can also replace sugar as a condiment.

Extended information:

Honey has two different physical states at normal temperature and pressure, namely liquid state and crystallized state (regardless of whether honey is stored in the nest cavity or removed from the nest room separated). Liquid honey is honey that is separated from the honeycomb and remains a transparent or translucent viscous liquid. However, after being left for a period of time, especially when the temperature is low, most varieties of honey gradually form a crystallized state, so the honey is called crystallized honey.

Honey should be stored in a cool, dry, clean, and ventilated place, and the temperature should be maintained at 5 to 10°C. In an environment where the air humidity does not exceed 75%. The container containing honey should be tightly closed to prevent air leakage and reduce the contact between honey and air.
