Problems solved by technology

The Chinese patent technology "A Composite Aroma-Producing Microorganism and Its Preparation Method and Application" discloses a microorganism that improves aroma. The content of the substance; the patented technology "a microbial agent for tobacco and its preparation method and application" discloses a microbial agent prepared from Candida utilis and Bacillus subtilis, which has a certain degradation fused ring Aromatics, but the ability to degrade nitrite is poor, and the ability to improve aroma and tobacco quality is poor, so it is not suitable for popularization
The patented technology "a method of compound microbial fermentation to improve the quality of tobacco sheets" uses the compound microbial liquid of lactic acid bacteria and golden flower bacteria to evenly spray on the surface of tobacco sheets to improve the quality of tobacco, but the cellulose degradation rate is low and cannot be degraded. Harmful material defect

Embodiment 1

[0025] A method for improving the quality of tobacco and reducing harmful substances, comprising the steps of: evenly spraying the compound bacterial agent on the tobacco leaves according to the mass ratio of 1:200, maintaining the temperature at 30°C, fermenting for 10 days, and then cooling down to 20 ℃, static aging 4d.

[0026] The composite microbial agent is prepared according to the following process:

[0027] Mix the Lactobacillus plantarum fermentation broth and the Trichoderma viride fermentation broth evenly at a volume ratio of 1:1, then add 2wt% cellulose, cultivate at 30°C for 12 hours, then add 2 times the volume of Bacillus pumilus fermentation broth, mix evenly, Instantly.

[0028] The plantarum lactobacillus fermentation broth is prepared according to the following steps:

[0029] Lactobacillus plantarum seed solution (1 × 10 8 cfu / ml) according to the inoculation amount of 8% volume ratio, transferred to the fermenter for 36 hours to obtain the Lactobacil...

Embodiment 2

[0036] The influence of each substance content in tobacco after the inventive method is processed:

[0037] Take Example 1 as an example; blank control group: do not use compound bacterial agent for treatment, replace the compound bacterial agent with clear water; comparative example 1 group: only add Lactobacillus plantarum and Trichoderma viride, do not add Bacillus pumilus; comparative example 2: Only Lactobacillus plantarum and Bacillus pumilus were added, and Trichoderma viride was not added; Comparative Example 3: only Trichoderma viride and Bacillus pumilus were added, Lactobacillus plantarum was not added; Comparative Example 4: only Trichoderma viride was added. The method of treating tobacco with the composite microbial agent of each comparative example is the same as that of Example 1, and the tobacco samples are the same, which are comparable.

[0038] 1. The degradation rates of cellulose, pectin, protein and starch are shown in Table 1, and the degradation rate=(...

Abstract

The invention belongs to the technical field of tobacco, and discloses a method for improving tobacco quality and lowering harmful substances. The method comprises the following steps of uniformly spraying complex microbial inoculants to tobacco leaves according to the mass ratio of 1:200, maintaining the temperature at 30 DEG C, conducting fermentation treatment for 10 d, then reducing the temperature to 20 DEG C and standing and ageing for 4 d. According to the method for improving the tobacco quality and lowering the harmful substances, the sour fragrance and the aged fragrance of the tobacco can be improved, the fragrance is rich and natural, the fineness is improved, and the contents of polycyclic aromatic hydrocarbon substances and nitrosamine nitrogen can be further lowered.

Description

technical field [0001] The invention relates to the technical field of tobacco, in particular to a method for improving the quality of tobacco and reducing harmful substances. Background technique [0002] Nicotiana is a tubular flower family, Solanaceae annual or limited perennial herb, slightly lignified base. Inflorescence terminal, conical, many flowers; capsule ovate or oblong, about equal to persistent calyx, flowering and fruiting in summer and autumn. Tobacco is mainly distributed in South America, South Asia, and China. It is an annual or limited perennial herb, all covered with glandular hairs; the roots are strong. The role of tobacco is cigarettes. [0003] As we all know, long-term smoking seriously threatens life and health. Smoking can induce lung cancer and laryngitis, bronchitis, emphysema and other respiratory diseases. Various conditions caused by smoking have become a global concern. How to improve the quality and aroma of tobacco while reducing the ...
