The application provides a method for determining essence and flavor in oil, which comprises three main steps of sample pretreatment, purification and analysis and test, the influence of the presence of lipids and proteins in the oil on the extraction efficiency of the target essence and flavor is avoided by removing grease and impurities in the sample pretreatment stage; the determination method adopts a solid phase extraction-gas chromatography analysis method, the extract is purified through a solid phase extraction column and separated through a polar chromatographic column, has the advantages of small matrix interference and fast analysis speed, and through reasonable purification and purification path and analysis and test means, the detection sensitivity is improved, and the detection limit and the quantitative limit are reduced. The application can simultaneously determine vanillin, methyl vanillin, ethyl vanillin, ethyl maltol and 2,3,5-trimethylpyrazine, five kinds of essence and flavor in oil, realizes simple pretreatment operation, good purification effect and higher sensitivity quantitative detection, and provides technical support for oil quality evaluation and edible oil safety supervision.

This invention discloses a tobacco flavoring, its preparation method, and its application, belonging to the field of tobacco processing technology. The flavoring comprises a cigar tobacco extract prepared by hot reflux extraction of cigar tobacco leaves with ethanol, followed by LX-8 macroporous adsorption resin column chromatography and precise collection and concentration of the 90% volume fraction of ethanol eluent. It preferably contains specific modifying components such as coffee extract, methyl ionone, and ethyl maltol, as well as propylene glycol. The key to its preparation method lies in mixing the components under an inert atmosphere, followed by dynamic aging and static aging treatments, with pH stability as the aging endpoint criterion. Applying this flavoring to reconstituted tobacco leaves and cigarettes can specifically enhance the natural tobacco aroma weakened by the tar reduction process, and significantly improve the harmony, purity, and aftertaste comfort of the aroma, effectively solving the technical problem of poor integration between traditional added flavorings and the tobacco matrix.
