In addition, the test items include the average water content rate and the standard deviation of water content (the test is carried out by an oven method, and the test number is 10). The sensory quality evaluation was performed on two groups of cigars in months, and the scoring results are shown in table 1 below.

TABLE 1 evaluation results of water content and sensory quality of cigars alcoholized in experimental group and control group

It can be seen from the above table that the standard deviation of the moisture content of the cigar sample alcoholized by the cigar fresh air circulation alcoholization method provided by the present invention gradually becomes smaller with the prolonging of alcoholization time, and is obviously lower than that of the control group which adopts the conventional alcoholization method at the same time. This shows that the alcoholization method provided by the present invention can provide a more stable and consistent alcoholization environment for cigars and can reduce the quality difference between different products in the same batch.

The evaluation results of fragrance, offensive odor, irritation and aftertaste showed that the evaluation results of the experimental group of the present invention were higher than those of the control group at each test period. The alcoholization method provided by the invention can obviously improve the alcoholization effect of the cigars and improve the product quality. Experimental data show that the cigars alcoholized for 3 months by the alcoholization method can reach the same quality as cigars alcoholized for 5-6 months by the conventional alcoholization method.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
