Zusammenfassung: | The invention discloses a traceability analysis method for natural components in flavoring essence, which comprises the following steps: sample preparation: putting a natural monomer flavoring raw material sample and a to-be-analyzed sample into a headspace bottle, dispersing and shaking uniformly; online headspace solid-phase micro-extraction: taking the headspace bottle into an incubator by an automatic sampler, and carrying out solid-phase micro-extraction; performing GC-MS (gas chromatography-mass spectrometry) analysis to obtain spectrograms of the natural monomer perfume raw material sample and the to-be-analyzed sample; qualitatively analyzing the spectrogram of the natural monomer perfume raw material sample to obtain characteristic peak information; qualitatively analyzing the spectrogram of the sample to be analyzed, comparing the characteristic peaks of the components with the characteristic peaks of the natural monomer perfume raw material samples, and determining the types of the added monomer pe |
