Abstract

The invention discloses a method for preparing reconstituted tobacco in low crotonaldehyde release amount. Neutral protease, pectinase, and glucoamylase are used to remove precursor substances generating crotonaldehyde. An alkaline process is used to preprocess tobacco raw materials and a low concentration slurring technology is used to improve bulk of reconstituted tobacco, and a combustion improver is added to improve combustion performance of the reconstituted tobacco, so as to reduce crotonaldehyde release amount in main stream smoke of the reconstituted tobacco. The method has great importance in reducing tar and harmful components of cigarette.

Description

technical field [0001] The invention belongs to the technical field of reconstituted tobacco leaves, and in particular relates to a method for preparing reconstituted tobacco leaves with low crotonaldehyde emission. Background technique [0002] CO, HCN, NNK, NH in cigarette mainstream smoke 3 , benzo[a]pyrene, phenol, and crotonaldehyde as the direction and main task of harm reduction in Chinese-style cigarettes. Reconstituted tobacco leaves are one of the important means of reducing harm and tar in cigarettes. It is necessary to develop reconstituted tobacco leaves that can reduce harmful components such as crotonaldehyde, so as to promote the realization of "harm reduction and tar reduction" in cigarettes. However, there is currently no effective method for manufacturing reconstituted tobacco leaves with a lower crotonaldehyde emission. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a method for preparing...
