Problems solved by technology

Most of the currently commercially available tobacco extracts are prepared by ethanol continuous extraction, which has two major disadvantages: ① part of the natural aroma is lost during the extraction process, and the aroma of the product is weak; ② in addition to the aroma components in the product, there are also pectin, Proteins and hemicellulose substances, these substances will be cracked during the smoking process of cigarettes to produce some harmful components, and at the same time increase the irritation and miscellaneous gas of smoking, and affect the sensory quality (Song Peng. Microbial fermentation reduces harmful components in cigarette smoke and improving the quality of cigarettes [D]. Xi'an: Northwest University, 2008.; Chi Jingji, et al. Correlation analysis

Example Embodiment

[0022] Example 1

[0023] The preparation method of high aroma tobacco extract in this embodiment includes the following steps:

[0024] 1) Weigh 1 kg of flue-cured tobacco raw materials, place the raw materials in a SY-III-A experimental tobacco processor, spray propylene glycol with 6% of the raw material mass uniformly, and place it in a sealed place for 11 hours to fully absorb the tobacco leaves, and then heat to 90°C for baking 1.5h;

[0025] 2) Crush the baked raw materials to 100 meshes, and add 95% ethanol for extraction, the mass ratio of material to liquid is 1:9, the extraction temperature is -20°C, and the time is 12h; after the extraction, filter with 400 mesh filter cloth Extract the extract, add the solvent to the filter residue and extract again, and combine the two extracts;

[0026] 3) The extract is separated with a 5kD ultrafiltration membrane, the permeate is collected and distilled under reduced pressure until there is no low-boiling solvent to obtain a concent...

[0028] Example 2

[0029] The preparation method of high aroma tobacco extract in this embodiment includes the following steps:

[0030] 1) Weigh the flue-cured tobacco raw materials, spray 18% propylene glycol of the raw material mass evenly on the flue-cured tobacco raw materials, place it in a sealed place for 9 hours to fully absorb the tobacco leaves, and then heat to 130°C for 0.5h;

[0031] 2) Crush the roasted raw materials to 80 meshes, and add absolute ethanol for extraction. The material-to-liquid mass ratio is 1:6, the extraction temperature is 0°C, and the time is 10 hours; after the extraction, use a 400-mesh filter cloth to filter and extract. The extract, filter residue and solvent are extracted once more, and the two extracts are combined;

[0032] 3) The extract is separated with a 10kD ultrafiltration membrane, the permeate is collected and distilled under reduced pressure until there is no low-boiling solvent to obtain a concentrate;

Abstract

The invention discloses a method for preparing a high-fragrance tobacco extract and belongs to the technical field of a tobacco additive. The method comprises the steps of 1, adding propylene glycol into tobacco raw materials, and then standing and baking the raw materials; 2, crushing, adding solvent extraction liquid into crushed materials; 3, filtrating extraction liquid with an ultra-filtration membrane to prepare permeate liquid, and decompressing and distilling the permeate liquid to prepare a condensate; and 4, secondarily separating the condensate by a molecular distillation method, and collecting a light component as the high-fragrance tobacco extract. In the preparing method, tobacco raw materials are in advance treated by baking so that Maillard reaction presents between the tobacco reducing sugar and the nitrogen-containing compound, generate pyrone and furanone substances are prepared and baking fragrance is increased; propylene glycol is added into the tobacco so that bad flavor caused by charred tobacco at high baking temperature can be prevented; macro-molecular substances and high boiling-point non-volatile substances can be effectively removed by the membrane separation-molecular distillation double separation process, and specific aroma components enriched in the tobacco are separated.

Description

technical field [0001] The invention relates to a method for preparing a high-aroma tobacco extract, belonging to the technical field of tobacco additives. Background technique [0002] In recent years, with the effective implementation of the Framework Convention on Tobacco Control, the gradual expansion of the scope of smoking bans in public places around the world, and consumers' increasing concern for their own health, the research and development of low-tar cigarette products has become increasingly important. But at the same time, it is inevitable that the aroma and taste of cigarettes will decline, and adding flavor to cigarettes is an important method to improve the taste. [0003] Tobacco extract is extracted from tobacco and contains tobacco's original aroma-causing substances. Compared with other natural flavors, tobacco extract has better harmony with cigarettes, which can enhance the aroma of cigarettes and increase the sense of satisfaction. Prepare a high-aro...
