Problems solved by technology

[0003] At present, the cigar fermentation process usually adopts a constant temperature fermentation method. For example, Qiao Baoming studied the influence of different temperature gradients on the quality of cigar filler tobacco leaves, and found that with the increase of temperature, the intensity of fermentation increases, and the color of tobacco leaves gradually becomes darker. There are also significant changes in chemical composition coordination and smoking quality, but too high temperature will lead to over-fermentation and reduce the quality of fermented tobacco leaves

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 ...

Abstract

The invention discloses a temperature-variable fermentation method of cigar tobacco leaves, which comprises the following steps: step 1, preparing the cigar tobacco leaves, and adding water into the cigar tobacco leaves to regain moisture until the initial moisture is 30% for later use; step 2, filling the cigar tobacco leaves dampened in the step 1 into a gunny bag, putting the gunny bag into a fermentation room for variable-temperature combined fermentation at the combined temperatures of 35 DEG C, 40 DEG C and 45 DEG C, and performing fermentation in three stages for 10 days in each stage; and step 3, performing moisture balance on the tobacco leaves after fermentation in the step 2 until the moisture content of the tobacco leaves is 20 + / -1%. Compared with constant-temperature fermentation, variable-temperature combined fermentation has the advantages that the reducing sugar content and the total sugar content can be remarkably increased, the alkaloid content can be reduced, and irritation and offensive odor can be remarkably improved on the premise that the aroma richness and the aroma amount are reserved to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a variable temperature fermentation method of cigar tobacco leaves. Background technique [0002] In recent years, the sales volume of the domestic cigar market has grown rapidly, while the shortage of domestic high-quality cigar raw materials has greatly restricted the healthy and sustainable development of the domestic cigar industry. Fermentation can effectively improve the maturity and mellowness of cigar leaves, reduce impurities and irritation, and improve the quality and homogenization of cigar leaves. Different from single-bacteria fermentation, the fermentation production of cigar tobacco leaves belongs to multi-bacteria mixed solid-state fermentation. During the fermentation process, macromolecular substances such as protein, starch, and cellulose are degraded into low-molecular-weight compounds under the action of fungi and bacteria, which are further transf...
