Abstract

The regenerated papermaking process tobacco leaching and concentrating process includes the leaching of tobacco material and the concentration of the leached liquid, and features that enzyme preparation is first added into tobacco material before leaching to enzymolyze water insoluble macro molecular compounds and urea, ammonium dihydrogen and other ammonia compound are added into the concentrate. Essentially, the enzymolysis before leaching converts water insoluble macro molecular compounds in tobacco into water soluble small molecular compounds so as to raise the leaching rate greatly, and the added ammonia compounds takes mailard reaction with enzymolyzed small molecular compounds to produce more specific tobacco scent matter in the concentrated liquid.

Description

technical field [0001] The present invention relates to the tobacco processing industry, in particular to a process for leaching and concentrating reconstituted tobacco leaves by a papermaking method. According to the different chemical properties, different enzyme preparations are added to pretreat the production raw materials, and ammonia compounds and other substances are added during the concentration process, so that the substances that are not conducive to tobacco combustion can be transformed into flavor substances that are beneficial to tobacco combustion. Background technique [0002] Papermaking reconstituted tobacco leaves use waste tobacco stems, tobacco powder and other raw materials in the cigarette manufacturing process, and comprehensively utilize leaching, separation, recombination, papermaking and other technologies to produce sheet-like substances that meet the needs of cigarette formulations and are close to natural tobacco. The application of reconstitut...
