Abstract:
Objective:To analyze the odorous components and their contents in raw products, wine-processed products, vinegar-processed products and wheat bran-processed products of Periplaneta americana. Method:Headspace solid-phase microextraction (HS-SPME) was used to extract the volatile components from different processed products, the chemical compositions were analyzed by gas chromatography-mass spectrometry (GC-MS), and the relative contents of each component was calculated by peak area normalization method. Result:A total of 41, 32, 40 and 47 components were respectively identified from raw, wine-processed, vinegar-processed and wheat bran-processed products of P. americana, involving a total of 13 common components. Conclusion:The odorous components in the raw products are mainly derived from aldehydes, alcohols, amines, hydrocarbons and other volatile substances. Odorous components can be reduced effectively and flavoring substances can be increased by wine, vinegar and wheat bran processing. This study provides a scientific basis for the further study of correcting odor of P. americana, it also provides a reference for analysis and correction of odor of animal medicines.
