Original title: Professor Li Jianke: Metabolic spectrometry analysis reveals the effect of increased yield and pulping time on the quality of bee king pulp
Research points:
As the yield of royal jelly (RJ) increases, the abundance of metabolites in RJ remains basically the same.
increase in RJ production does not change its moisture content or antibacterial activity.
content of 10-hydroxy-2-phenyric acid (10-HDA) meets the requirements of China's high-quality RJ.
similar metabolic characteristics of RJ, which was pulped at 48 h and 72 h after the insect was removed.
24 h harvests have a higher RJ quality than 48 h and 72 h.
royal jelly (RJ) is a natural secretion of bees and a healthy functional food. To study the changes in RJ quality with increased yield and harvesting period, the Key Laboratory of Pollinator Insect Biology of the Ministry of Agriculture and Rural Affairs, Chuan Ma, Licui Zhang, Mao Feng, Yu Fang, Han Hu, Bin Han, Lifeng Meng and Jianke Li of the Chinese Academy of Agricultural Sciences compared Italy The metabolism of bees (Italian bees, ITBs) and RJ-production bees (RJ-production bees, RJBs) harvested from ITBs after the transfer of insects at 24 h, 48 h and 72 h. 77 high-abundance compounds were identified using inverse liquid chromatography and hydrothermic liquid chromatography-high-resolution mass spectrometrometrography.
found that the metabolite abundance, water content and antibacterial activity of the bee paste syrup picked by the two bees remained largely unchanged, indicating similar RJ quality. It is worth noting that the 10-hydroxy-2-phenolic acid levels observed in RJBs (1.98%) and ITBs (2.41%) meet the chinese high-quality RJ standards. RJ harvested at 48 h and 72 h has a similar metabolic spectrum, indicating that the two harvesting methods have little effect on RJ quality. 24 h harvesting results in higher RJ mass, higher abundance of many bioactive compounds and lower moisture content. The research data are mainly based on RJ metabolic components, which provide the basis for mass production of high-quality RJ.
