Rapid Identification of Odor Difference of Honey Fried Huangqi(Astragalus Membranaceus)before and after Processing by Electronic Nose
Objective:The odor changes of honey fried Huangqi(Astragalus membranaceus)before and after processing,were studied by electronic nose method,to establish a rapid method for identifying raw and honey fried Huangqi(Astragalus membranaceus).Methods:An electronic nose was used to collect the odor fingerprint of raw and honey fried Huangqi(Astragalus membranaceus),and the information of odor components was obtained by comparison with AroChemBase database.According to AlphaSoft(Toulouse Company,France)software combined with peak area analysis,the variation rule of odor components was analyzed and multivariate statistical analysis was earried out.Results:Through the analysis of raw and honey fried Huangqi(Astragalus mem-branaceus)odor fingerprint,14 odor characteristic components were matched and 7 odor different components were inferred.Conclusion:Electronic nose can quickly identify the characteristic odor components of honey fried Huangqi(Astragalus membranaceus)before and after processing.
