The quality of honey

The "Shen Nong Ben Cao Jing" lists honey as a top grade that is beneficial to humans. The ancient Greeks considered honey to be a "gift given by God," and modern nutritional analysis shows that honey contains about 35% glucose and 40% fructose. It can be directly absorbed and utilized by the body without digestion. Honey also contains a variety of inorganic salts similar to human serum concentrations, but also contains a certain amount of vitamin B1, B2, B6 and iron, calcium, copper, manganese, phosphorus, potassium and so on. Honey contains amylase, lipase, invertase, etc. It is one of the most enzymes in food. The smell of honey is fragrant and delicious. From the point of view of nutrition and health care, it is not only a product that nourishes and prolongs life, but also a good medicine for curing diseases.

According to a survey conducted by the Shaanxi Provincial Bee Association, this year's reduction in the supply of honey caused a gap between supply and demand, which caused market prices to rise. In particular, honey, rapeseed, and other honey varieties are only about 70% of the annual output, and some unscrupulous merchants are pursuing the greatest interest in operating their businesses. The illegal operation of counterfeit honey caused a certain impact on the apiculture market. There are several ways to identify honey:
