The invention provides a method for improving the quality of cut stems. The method comprises the following steps that (1) tobacco stems are washed and degraded; (2) moisture regain is conducted on the tobacco stems and the tobacco stems are stored; (3) the tobacco stems are expanded and pressed; (4) stem pieces are degraded and stored; (5) material adding is conducted on the stem pieces; (6) the stem pieces are dried; (7) the dried stem pieces are stored; (8) moisture regain is conducted on the dried stem pieces and the dried stem pieces are expanded and pressed; (9) the stem pieces are cut into shreds and materials are added; (10) the cut stems are expanded and dried. Cigarettes with the cut stems prepared through the method are clear in fragrance characteristic, the fragrance quality is good, the smoke state is improved, the fine and smooth performance is improved, the harmony is better, miscellaneous gases are reduced, the dry sensation is reduced, and taste is more comfortable.

The invention discloses a method for making papaya liquor, and relates to the technical field of health-care liquor. According to the method, papayas, cereals and rice are fermented to obtain papaya fermented grains, cereal fermented grains and rice fermented grains respectively, and then three-stage distillation is carried out after the papaya fermented grains, the cereal fermented grains and the rice fermented grains are mixed; a method of respective fermentation of the papayas, the cereals and the rice is adopted, in the fermentation process, microorganisms in distiller's yeast take the papayas as raw materials, the papayas are saccharified and decomposed, nutritional components in the papayas are released fully, generated ester and acid substances are relatively large in quantity, the content of alcohol is relatively reduced, the prepared papaya liquor is high in yield, unique in flavor, mellow and sweet in taste, rich in aroma, pure and delicious.

The invention belongs to the technical field of flavors and fragrances, and proposes a preparation method of snowflake pear extract for tobacco, comprising the following steps: A, washing the snowflake pear, peeling and removing the core, cutting into pieces, adding a pretreatment agent, and dehydrating after beating , to obtain snowflake pear pretreatment; said pretreatment agent is formed by mixing ascorbyl palmitate and sorbitol with a mass ratio of 1 to 2:7; B, getting half of the quality snowflake pear pretreatment, The fraction is 60% ethanol leaching, filtering, and concentrating to obtain the first extract; C, taking the other half of the quality of snowflake pear pretreatment, leaching with ethyl propionate, filtering, and concentrating to obtain the second extract; D. Mixing the first extract and the second extract to obtain the snow pear extract for tobacco use. Through the above technical scheme, the problems of low content of flavonoids and low extraction rate in the snowflake pear extract obtained by the extraction method in the prior art are solved.

The invention discloses pericarpium citri reticulatae viride extract for cigarettes and an application of the extract. The pericarpium citri reticulatae viride extract for cigarettes takes pericarpium citri reticulatae viride as a raw material and is prepared through solvent extraction and steam distillation. After the obtained pericarpium citri reticulatae viride extract for cigarettes is added into flue-cured type cigarette leaf groups, the extract exerts an important function of improving the quality of the cigarettes, according to sensory evaluation. A preparation method of the pericarpium citri reticulatae viride extract for cigarettes is simple in process. Simple equipment are employed; the cost is low; and the pollution is little. The component analysis indicates that the obtained extract is high in total content of aroma components, and the aroma components are of abundant types. According to the organoleptic evaluation, the obtained extract can effectively improve the smoke quality of the cigarettes.

The invention discloses a preparation method of a tomato extract and application of the tomato extract in cigarette production. The preparation method comprises the following steps: juicing fresh tomatoes, adding honey and amino acids into the fresh juice and then stirring the juice to react to obtain a tomato extract precursor, then adding potassium hydroxide and a catalyst into the precursor, heating the precursor to react to obtain an original extract of the tomato extract, adding ethanol into the original extract to extract, filtering an extracting solution, concentrating the filtrate at a reduced pressure to obtain ethanol concentrate, then adding deionized water into the filtrate to distill and collecting a fraction so as to obtain a fraction I and a residue; adding residual ethyl acetate into the residue for extraction, filtering the extracting solution, concentrating the filtrate at the reduced pressure to obtain ethyl acetate concentrate, then adding deionized water into the concentrate to distill and collecting a fraction so as to obtain a fraction II; and uniformly mixing the fractions I and II to obtain the tomato extract. The tomato extract applied to cigarettes is quite obvious in effect, and can enhance the aroma harmony of the cigarettes, increase the re-sweet feel and sweet feel of smoke, reduce the irritation of the smoke of the cigarettes and effectively improve the comfort level of the cigarettes.
