| titleOfInvention | Preparation method of a burnt-sweet aroma latent aroma substance and latent aroma type reconstituted tobacco leaves |
| abstract | The invention discloses a method for preparing a burnt-sweet aroma latent aroma substance and a latent-aroma type reconstituted tobacco leaf. The former preparation method comprises: surface carboxylation and acyl chloride modification of wood pulp fibers, and then adding a burnt-sweet aroma source The esterification reaction is carried out to obtain the latent aroma substance with a burnt-sweet aroma, and the source of the burnt-sweet aroma is at least one of maltol and ethyl maltol. The obtained fiber-type latent aroma substance is added to the slurry of reconstituted tobacco leaves, and the latent-aroma type reconstituted tobacco leaves are obtained through processes such as beating and papermaking. The present invention loads volatile small-molecule fragrance substances such as maltol and/or ethyl maltol on the surface of wood pulp fibers through a heterogeneous chemical reaction to obtain fiber-type latent fragrance substances. The preparation method is simple, reliable, low in cost and easy to popularize. The latent flavor reconstituted tobacco leaves can be decomposed during the burning process of cigarettes to release the aroma substances of burnt sweet aroma, which can reduce the woodiness and irritation of reconstituted tobacco leaves, and provide a new way for the development of low-tar and low-harm cigarettes with characteristic flavors . |
