The physical and chemical parameters of lavender honey were detected based on published standards.The volatile compounds in lavender honey were determined by headspace solid-phase micro-extraction coupled with gas chromatography and mass spectrometry.Results showed that the contents of moisture, acidity, diastase number, and hydroxymethylfurfural were 14.4%-20.7%, 11.4-39.3 mL/kg, 4.2-27.7 mL/(g·h), and 1.6-12.0 mg/kg, respectively.The sum amount of the fructose and the glucose ranged from 65.5% to 75.0%, and the sucrose content was 0.1%-5.8%.The sucrose contents of four lavender honey exceeded the national standard of <5%, while meeting the CAC (Codex Alimentarius Commission) standard of <15% and all the other physical and chemical parameters met the requirements of national and industry standards.Seventy-five different volatile compounds were identified in lavender honey, and the alcohols (54.2%), aldehydes (32.5%), and acids (6.1%) were the main types of volatile compounds.The dominant compounds were hexanol (26.0%), phenylacetaldehyde (20.0%), and heptanol (13.1%).Compared with the published data of rape honey, jujube honey, and acacia honey, the results showed that heptanol and hexanol were only detected in lavender honey, and the contents of heptaldehyde and hexanal were both higher than that in other types of honey.In summary, heptaldehyde, hexanal, heptanol, and hexanol can be identified as the characteristic volatile component in lavender honey.
