Description

Cigar tobacco leaf screening treatment method Technical Field The patent belongs to the technical field of cigar processing, and particularly relates to a cigar tobacco leaf screening treatment method. Background The cigar tobacco leaves are taken as a natural agricultural product, and the cigar tobacco leaves are easy to mildew in the storage process because the cigar tobacco leaves are an ideal substrate for mold growth while the cigar tobacco leaves are endowed with unique flavor by high sugar, high protein and rich organic matters. In the fermentation process, the temperature and humidity control conditions are required to promote the vigorous biochemical reaction in the tobacco leaves, so that the mildew rate of the finished tobacco rods prepared by using the fermentation product is greatly improved. Thus, a new treatment process is needed to reduce the rate of the finished cigarette mould. Disclosure of Invention The patent aims to provide a cigar tobacco leaf screening treatment method, which achieves the aim of reducing the mould change rate of finished cigarettes. For solving the technical problem, the patent adopts the following technical scheme: a cigar tobacco screening treatment method comprises the following steps: Step 1, measuring initial mould content of cigar tobacco leaves, screening and grading according to the initial mould content, When the initial mould content is 103-10 5 CFU/g, marking cigar tobacco leaves as normal raw materials; when the initial mould content is more than 10 5 CFU/g, marking cigar tobacco leaves as high-risk raw materials; step 2, carrying out flexible dampening treatment on normal raw materials or high-risk raw materials, wherein the flexible dampening treatment time is 20-25 min, 25-30 min, 30-40 min, 40-50 min or 50-60 min, so as to obtain a flexible dampening product; the temperature of the flexible conditioning treatment of the high-risk raw materials is 58-59 ℃; The temperature of the normal raw materials for flexible conditioning treatment is 62-65 ℃; Carrying out stacking fermentation treatment on the flexible moisture regain product, wherein the time of the stacking fermentation treatment is 10-35 days, and the mould content in the stacking fermentation treatment process is lower than 10 6 CFU/g, so as to obtain a stacking fermentation product; And 3, carrying out intensified moisture regaining treatment on the stacked fermentation products to obtain intensified moisture regained products, wherein the intensified moisture regained products are used for preparing aerosol-generating products, and the mildew rate of finished products after 90 days of alcoholization of the aerosol-generating products is less than 0.0050%.
