A method for improving the tensile strength and sensory quality of reconstituted tobacco leaves

Abstract

The invention provides a method for enhancing the tensile strength and the sensory quality of reconstituted tobaccos. The method particularly includes chopping radix glycyrrhizae, then mixing the radix glycyrrhizae and flos chrysanthemi with each other to obtain mixtures, and ultrasonically extracting the mixtures by the aid of ethyl alcohol solution to obtain plant residues and extract liquid A;allowing the extract liquid A to stand still, filtering the extract liquid A, then carrying out vacuum concentration until semi-flow extract is obtained, adding glycine and propylene glycol into the semi-flow extract, carrying out Maillard reaction and collecting Maillard reactants; mixing the plant residues, tobacco stems and tobacco powder with one another, adding the plant residues, the tobaccostems and the tobacco powder into water to obtain mixtures, extracting the mixtures to obtain insoluble matters and extract liquid B, grinding the insoluble matters into thick liquid, adding diatomaceous earth into the thick liquid, uniformly mixing the thick liquid and the diatomaceous earth with each other and then making paper with pulp by the aid of papermaking machines to obtain reconstituted tobacco substrates; carrying out vacuum concentration on the extract liquid B, then adding the Maillard reactants into the extract liquid B, uniformly stirring the Maillard reactants and the extractliquid B with one another to obtain mixtures and then coating the mixtures on two sides of each reconstituted tobacco substrate to obtain the reconstituted tobaccos. The method has the advantages that the radix glycyrrhizae and the flos chrysanthemi are used as added plant raw materials, accordingly, the tensile strength of the reconstituted tobaccos can be improved, and the method can be favorable for improving the sensory quality of the reconstituted tobaccos; the flos chrysanthemi contains large quantities of flavonoid components, and good effects can be realized for coloring the substrates in follow-up procedures.

Description

technical field [0001] The invention relates to the field of cigarette manufacturing, in particular to a method for improving the tensile strength and sensory quality of reconstituted tobacco leaves. [0002] technical background [0003] Reconstituted tobacco leaves are mainly made of tobacco stems, tobacco powder, tobacco fragments, etc., and are processed according to the papermaking process to prepare thin slices close to natural tobacco leaves, which are used in cigarette production as a cigarette raw material. However, due to the low amount of fiber contained in tobacco stems, tobacco dust, and tobacco fragments, and the short length and insufficient strength of the fibers, it is often necessary to add a certain proportion of external fibers to make up. [0004] Some natural plants contain a lot of plant fibers and have high tensile strength, such as licorice, chrysanthemum, etc., and these natural plants contain special aroma components, which have good harmony with ci...

Problems solved by technology

This invention does not extract natural plants separately, which causes the loss of natural plant aroma components to a certain extent and reduces the application effect of natural plants
