The Classification Of Royal Jelly

May 06, 2020

According to bee species: According to different bee-producing bee species, royal jelly is divided into middle bee jelly, western bee jelly and black bee jelly. The former is produced by Chinese honey bees and the latter is produced by western honey bees. Compared with western bee jelly, middle bee jelly is more viscous in appearance,Royal Jelly light yellow, and slightly lower in royal jelly. The output of medium royal jelly is much lower than that of western royal jelly. The vast majority of sales on the market are Western Bee Jelly. Black royal jelly is mainly produced in Heilongjiang and Qinghai provinces. The output of black royal jelly is lower than that of western royal jelly, but the nutrition is higher than that of western royal jelly, and the quality of royal jelly is high. The hotter the west royal jelly, the better, and the fresher the black royal jelly, the better, similar to the sweetness of taste.

According to physical and chemical indicators: It is more scientific to determine the grade of royal jelly according to the classification of physical and chemical indicators. Royal jelly contains 10-hydroxy-△ 2-decenoic acid (10-HDA),Royal Jelly which is unique in nature. China exports royal jelly basically according to this index To determine the quality and price, and is recognized by foreign customers. According to Chinese National Standards,Royal Jelly the first-grade royal jelly 10-HAD index is greater than 1.4%,Royal Jelly and when the 10-HDA index is greater than 2.0, it is the best in royal jelly.

Royal jelly can be divided into low-yield (ordinary) pulp and high-yield pulp: Because royal jelly is a labor-intensive product and its output is very low, generally a group of bees can only produce 3-4 kg of royal jelly a year,Royal Jelly so the production cost is very high. After years of breeding,Royal Jelly the scientific researchers have produced some bee species with relatively high pulp output, called pulp bees,Royal Jelly and the annual output of the swarm can reach 8-10 kg. Some breeding farms have bred bee species with an annual output of more than 13 kilograms of royal jelly. According to a large amount of analysis data,Royal Jelly the quality of high-yield pulp is slightly worse than that of low-yield pulp. The higher the output, the lower the quality.
