Preparation of fine processing products of tobacco extracts based on the membrane separation and column chromatography separation techniques

  • To make full use of the discarded tobacco leaves, and produce multiple fine processing products, tobacco extract was obtained from discarded tobacco leaves, and the tobacco extract was finely processed using membrane separation and two-dimensional column chromatography separation techniques. Sensory evaluation screened out characteristic flavor groups with prominent style features, and carried out recombination between characteristic flavor groups. Py-GC-MS was used to analyze the recombinant products. The results showed that the yield of tobacco extract obtained by water extraction was the highest and the overall sensory effect was good; A total of 16 groups were obtained through precision processing, among which the sensory effects of membrane separation of 5nm retention solution and column chromatography separation of A1, C1, and E2 fractions showed distinct characteristics, serving as the characteristic flavor groups of tobacco extracts; Among the recombinant products, products 1 and 2 can enhance the characteristics of tobacco aroma, baking aroma, light aroma, and sweet aroma of cigarettes, and have a good overall sensory effect; The thermal decomposition products of recombinant products 1 and 2 are mainly composed of heterocyclic and aromatic compounds, including sweet, light, nutty and other aroma types. This research provided reference to pluralism products preparation of natural flavors.
