Embodiment 1
[0024] A method for fermenting cigar tobacco leaves at variable temperature, comprising the following steps:
[0025] First, add water to the tobacco leaves to re-moisturize the initial moisture to 30%, and set aside.
[0026] Secondly, the rejuvenated tobacco leaves were subjected to variable temperature combined fermentation. The combined temperature was 35 °C, 40 °C, and 45 °C. The fermentation was divided into three stages, each stage was fermented for 10 days, and the fermentation time was 30 days in total. The temperature gradient settings are shown in Table 1. .
[0027] Thirdly, the cigar tobacco leaf samples after fermentation were dried and pulverized at 45°C, passed through a sieve with an aperture of 0.25 mm, and the content of total sugar, reducing sugar, total alkaloid and total nitrogen was determined by continuous flow method.
[0028] In the fourth step, the cigar tobacco leaf samples after the fermentation were dried and pulverized at 45° C., passed through ...
