Problems solved by technology

[0003] The existing technology has carried out many aspects of research on how to improve the extraction efficiency and remove the macromolecules in the extract, but there are still some technical defects
For example, the extraction process is relatively simple, and the aroma substances in tobacco cannot be fully obtained. The residue after simple extraction is directly discarded, resulting in the loss of aroma substances and waste of raw materials; The process is more complicated, the conditions are not easy to control, and it is difficult to produce on a large scale

Embodiment 1

[0022] Tobacco leaves are dried and crushed and then extracted with 95% ethanol solution at 60°C for 4 hours. The ratio of tobacco raw materials to ethanol is 1:3 。 After solid-liquid separation, the filtrate was concentrated under reduced pressure to obtain tobacco extract A with a solid content of 55%, and the moisture content of the filter residue was adjusted to 60%, and 1% cellulase, 1% hemicellulase, 0.5% Pectinase was enzymatically hydrolyzed at 50°C for 4 hours, and after solid-liquid separation, the filtrate was concentrated under reduced pressure to obtain tobacco extract B with a solid content of 60%. Add proline with a mass percentage of 4% to extract B, and mix Heat at 100°C for 45 minutes to obtain tobacco reactant C, and mix tobacco extract A and tobacco reactant C at a ratio of 1:1 to obtain tobacco aroma substances.

Embodiment 2

[0025] Tobacco dust produced during the production of cigarettes is collected, dried and extracted with 70% ethanol solution at 80°C for 2 hours. The ratio of tobacco raw materials to ethanol is 1:4 。 After solid-liquid separation, the filtrate was concentrated under reduced pressure to obtain tobacco extract A with a solid content of 60%, and the moisture content of the filter residue was adjusted to 70%, and 0.5% cellulase, 0.5% hemicellulase, 0.5% Pectinase and 1% protease were hydrolyzed at 55°C for 6 hours, and after solid-liquid separation, the filtrate was concentrated under reduced pressure to obtain tobacco extract B with a solid content of 50%, and 2% hydrogen phosphate by mass was added to extract B Diammonia and 30% glycerol were mixed and heated at 90°C for 100 minutes to obtain tobacco reactant C. Tobacco extract A and tobacco reactant C were mixed at a ratio of 2:1 to obtain tobacco aroma substances.

Abstract

The invention discloses a preparation method of a material with tobacco fragrance. The preparation method is characterized by sequentially comprising the following steps: 1, drying and pulverizing tobacco raw materials, then conducting extraction through an ethanol solution, conducting solid-liquid separation, then conducting decompression condensation on filter liquor, and obtaining tobacco extract A; adding a bio-enzyme preparation to obtained filter residues for conducting enzymatic hydrolysis, conducting solid-liquid separation, then conducting decompression condensation on filter liquor, and obtaining tobacco extract B; mixing the exact B, amino compounds and polyalcohol, conducting heating, making the mixture react, and obtaining a tobacco reagent C; 4, mixing the tobacco exact A and the tobacco reagent C in a certain proportion, and obtaining the material with tobacco fragrance. The preparation method of the material with tobacco fragrance is applicable to different varieties of tobacco products, and real, abundant and rich original tobacco fragrance can be supplied to the tobacco products.

Description

technical field [0001] The invention belongs to the technical field of tobacco, and in particular relates to a preparation method of a tobacco aroma substance, which can be added to various tobacco products, such as shredded tobacco of traditional cigarettes, heat-not-burn tobacco products, and e-cigarette liquid. Background technique [0002] The aroma substance extracted from tobacco is an important tobacco additive, which is widely used in the flavoring of various tobacco products. Its aroma is lifelike and natural, which can supplement the characteristic aroma of tobacco, reduce miscellaneous gas, and improve sensory quality. There are many extraction methods currently used, including traditional extraction methods such as steam distillation and solvent extraction, and emerging green extraction methods such as supercritical extraction and subcritical extraction. CN10322679A discloses a method for preparing tobacco shreds extract by high-pressure puffing-flocculation and ...
