Fermentation method for improving quality of cigar raw material

The invention relates to the field of cigar processing, and discloses a fermentation method for improving the quality of cigar raw materials. The method comprises the following steps: firstly, alternately stacking low-quality cigar raw materials and high-quality cigars for fermentation; water obtained by soaking the high-quality cigars is used as humidifying liquid in the fermentation process, that is, the high-quality cigars are used as additional media in the fermentation process in a liquid form; meanwhile, the moisture content is kept to be not less than 25% in the fermentation process, so that the smoking taste, the aroma richness of the cigar leaves and the like of the obtained cigar leaves can be greatly improved, the quality of cigar products is improved, and the cigar leaves can replace imported cigar raw materials to be used in cigar formulas. 本发明涉及雪茄烟加工领域，公开了一种提高雪茄原料品质的发酵方法。本发明首先通过低品质雪茄原料与高品质雪茄交替堆垛进行发酵；并将经过高品质雪茄浸泡得到的水作为发酵过程中的加潮液体，即以液体的形式，将高品质雪茄作为发酵过程的外加介质；同时，发酵过程中保持含水率不小于25％，由此得到的的雪茄烟叶，其吸味、烟叶香气丰富度等
