The Chinese Academy of Thermal Sciences has made new progress in the identification and excavation of bioactive ingredients in honey with Hainan characteristic bee species

 

The yellow-striped thornless wasp is a flowering plant in tropical rainforest and the main pollinator in Hainan's tropical characteristics
and efficient agriculture.
Geographical environment, honey source plants and bee species are the main factors
affecting honey quality.
Compared with traditional honey, thornless bee honey has the characteristics
of sour taste and high medicinal value.
At present, the active substance and function evaluation of thornless bee honey in tropical areas are not clear
.
The research team took the honey of hainan middle bee, large bee and yellow striped thornless bee as the research object, and compared the differences
in active compounds, antioxidant activity and microbial diversity of multi-flower honey of different bee species in the same habitat.
The results show that compared with the hainan bee honey and the big bee honey, the content of phenolic substances such as rutin, isopurine, syringe acid, gallic acid, ellagic acid, hesperidin, ferulic acid, total phenol and total flavonoids in the yellow striped thornless bee honey is 1 to 9 times higher, which can be used as an important characteristic substance
to distinguish between yellow-veined thornless honey and traditional honey.
Through correlation analysis, it was found that these phenols were significantly positively correlated with the antioxidant activity of honey, which proved that yellow-veined thornless honey has stronger antioxidant capacity
.
The results of microbial diversity sequencing analysis showed that the relative abundance of lactic acid bacteria in yellow stingless bee honey was as high as 96.
28%, which was significantly higher than that of Hainan bee honey (0.
67%) and large bee honey (1.
28%), which was the main reason for
its sweet and sour taste.

 

The research results were published in Food Research International under the title of "Bioactive Characterization of Multifloral HoNeys from Apis cerana cerana, Apis dorsata, and Lepidotrigona flavibasis" in Food Research International IF=7.
