The invention discloses a method for traceability analysis of natural components in an added flavor, comprising: sample preparation: placing a raw material sample of a natural monomer flavor and a sample to be analyzed in a headspace bottle, dispersing and shaking well; online headspace solid phase Microextraction: The headspace vial is taken into the incubator by the autosampler, and solid-phase microextraction is performed; GC-MS analysis is performed to obtain the spectrum of the natural monomeric aroma raw material sample and the sample to be analyzed; the spectrum of the natural monomeric aroma raw material sample Qualitative analysis of the graph to obtain characteristic peak information; qualitative analysis of the spectrum of the sample to be analyzed, compare the components with the characteristic peaks of each natural monomeric aroma raw material sample, and determine the type of monomeric aroma raw materials added; according to the response ratio of the characteristic peaks , semi-quantitative analysis of the proportion of natural fragrance raw materials added. The method for traceability analysis of natural components in the flavoring essence of the present invention utilizes the characteristic peaks of different natural flavoring raw materials to realize the traceability analysis and semi-quantitative analysis of the natural flavoring raw materials in the flavoring essence, and effectively complete the composition analysis of the flavoring essence. |
