A method for making carbon dioxide-expanded shredded tobacco highlight the burnt-sweet flavor

Abstract

The invention discloses a method for enabling carbon dioxide expanded tobacco to highlight the sweet aroma style. The method is characterized by comprising the steps that before tobacco leaf expansion, primary feed liquid is added into tobacco leaves, then carbon dioxide expansion is performed after tobacco leaves are shredded, and finally secondary feed liquid is added into the expanded tobacco shreds, wherein the primary feed liquid is water solutions of monosaccharide, disaccharide and polysaccharide, and the secondary feed liquid is prepared from heterocyclic oxygen spice, heterocyclic nitrogen spice, sweet aroma style tobacco essence molecule distillation light component, a sweet aroma style Maillard reaction product, tobacco source low molecular weight monomer spice and a fruit extract. The method can improve the physical structure of expanded tobacco and reduce technological residues, and can specifically compensate for aroma substance losses caused by expansion, add high-quality aroma in expanded tobacco, cover offensive odor, reduce irritation and reduce dryness sensation.

Description

technical field [0001] The invention belongs to the field of flavor design for tobacco, and specifically refers to a burnt-sweet fragrance style CO 2 Expanded cut tobacco additive design. Background technique [0002] Expanded shredded tobacco is an important part of the cigarette leaf formula, together with shredded tobacco, cut stems and reconstituted tobacco leaves, it constitutes the leaf formula of cigarettes. Currently, the commonly used expanded cut tobacco in the tobacco industry is CO 2 Expanded shredded tobacco is prepared by cutting the added tobacco leaves into shreds, impregnating them with liquid carbon dioxide, and sublimating and expanding them at high temperature. Adding CO to the cigarette leaf group 2 Expanded shredded tobacco can reduce the amount of tar released from cigarettes, reduce harmful components, and reduce the cost of cigarettes. However, carbon dioxide expanded shredded tobacco also has its significant defects. First, shredded tobacco is o...

AI Technical Summary

Problems solved by technology

[0005] 1) The current feeding is mainly added before the cut tobacco is expanded, and after the addition is treated with carbon dioxide at high temperature, whether it is a monomeric flavor or a natural flavor, it will cause the loss of aroma substances, increase the coke gas and other miscellaneous gases, and affect the feeding effect;

[0006] 2) Simply adding essence cannot reduce the key problem of broken shredded tobacco;

[0007] 3) Propylene glycol and ultra-large molecular weight sodium alginate are used as humectants, which have certain solubility problems, and the solution has a high viscosity, which makes it difficult to apply during production, and in addition, it is easy to cause clumping of cut tobacco after expansion;

[0008] 4) Adding more tobacco extracts to the expanded shredded tobacco, although it can increase the aroma, it will increase the residual taste and make the taste experience worse

It is concluded that the volatile aroma components of small molecules derived from tobacco are greatly reduced, sugar degradation and Maillard reaction products such as furanone are greatly reduced, and long-chain fatty acids are increased, resulting in a decrease in the aroma of expanded cut tobacco and a poor sense of balance

According to the production practice and sensory evaluation results, the broken cut tobacco, the increase of miscellaneous gas and the poor taste are also the problems that the addition of expanded cut tobacco hopes to solve.
