This invention provides a flavoring agent for enhancing the honey-sweet aroma of tobacco, comprising the following raw materials and their mass percentages: 0.2-0.3% 2,3-pentanedione, 0.45-0.55% phenylacetic acid, 0.45-0.55% phenethyl acetate, 0.25-0.4% phenylethanol, 0.45-0.6% methyl phenylacetate, 0.45-0.6% ethyl phenylacetate, 0.5-0.6% menthyl acetate, 0.15-0.25% geraniol, and the balance being propylene glycol. This invention belongs to the field of tobacco flavoring technology. By combining 2,3-pentanedione, phenylacetic acid, and phenethyl acetate in a specific mass ratio and conducting testing and evaluation, a flavoring agent suitable for enhancing the honey-sweet aroma of tobacco has been successfully developed. The composition is clearly defined, significantly improving the honey-sweet aroma of tobacco products, with a rich and long-lasting aroma, and good taste harmony.

The invention discloses a chitosan-based membrane as well as a preparation method and application thereof, and belongs to the technical field of packaging materials. The chitosan-based film has a double-layer structure consisting of an inner layer and an outer layer, the outer layer is a water-blocking antibacterial layer formed by a silver complex, and the inner layer is an antibacterial antioxidant layer formed by polyphenol; the silver complex is a complex which is formed by the reaction of pyrrole-2-formaldehyde-g-chitosan and silver acetate; the polyphenol is formed by grafting 3, 4-dihydroxy methyl phenylacetate on the chitosan. The silver complex water-blocking antibacterial layer is constructed on the outer layer, and the polyphenol antibacterial anti-oxidation layer is constructed on the inner layer, so that the double fresh-keeping mechanism of external protection and internal maintenance is realized, and the comprehensive performance and application potential of the material are remarkably improved.
