- Abstract
The volatile components of honey directly affect consumers' choices. In order to better develop local honey resources and increase product value, this study firstly compared the volatile components Triadica cochinchinensis honey (TCH) with 5 botanical origin honeys including jujube, chaste, acacia, rape and linden by using headspace solid-phase microextraction technology and gas chromatography-mass spectrometry. The results showed that a total of 81 compounds were detected in 6 kinds of honeys. N-octanal, β-phenylethyl alcohol and nonanal are the base aroma of honey, and contribute to the unique beeswax aroma and fruit rose aroma. A total of 29 compounds were detected in TCH, with n-heptanal and 2, 4, 5-trimethyl-1, 3-dioxolane being its characteristic compounds. Based on volatile substances, a discrimination model of honey botanical origin is established. Using receiver operating curve (ROC) to compare the performance of the classification model, it can be seen that the model has the best distinguishing effect in TCH and linden honey whose areas under curve (AUC) are both 0. 9979, but the model has a lower distinguishing performance for acacia honey (AUC=0. 7239). The results provide basic data of volatile components in TCH, and provide a reference for in-depth research on the same components of honey from different plants.
