Embodiment 1

[0024] The method for preparing cigar tobacco leaves by pectinase fermentation comprises the following steps:

[0025] 1) Alcoholize 30kg of the upper part of the cigar filler under natural conditions for one year, and then remoisturize the upper part under vacuum;

[0026] 2) dissolving pectinase in deionized water to obtain a pectinase solution, wherein the activity of pectinase in the pectinase solution is 900U / ml;

[0027] 3) placing the leaf stalk of the tobacco leaves treated with moisture resurgence in step 1) in a pectinase solution to soak the stalk for 30 minutes, and then spraying the pectinase solution on the tobacco leaves at a weight ratio of 1:10 to obtain tobacco leaves containing pectinase, wherein , in every gram of tobacco leaves containing pectinase, the enzyme activity of pectinase is 90U; let stand for 24 hours to balance the moisture in the tobacco leaves, and then adjust the moisture content of the tobacco leaves to 25%;

[0028] 4) Fermenting the toba...

Embodiment 2

[0031] The method for preparing cigar tobacco leaves by pectinase fermentation comprises the following steps:

[0032] 1) Aging 30kg of the middle part of the cigar filler under natural conditions for one year, and then re-moisture the upper part of the smoke under vacuum conditions;

[0033] 2) dissolving pectinase in deionized water to obtain a pectinase solution, wherein the activity of pectinase in the pectinase solution is 800U / ml;

[0034] 3) placing the leaf stalk of the tobacco leaves treated with moisture resurgence in step 1) in a pectinase solution to soak the stalk for 20 minutes, and then spraying the pectinase solution on the tobacco leaves at a weight ratio of 1:10 to obtain tobacco leaves containing pectinase, wherein , in every gram of tobacco leaves containing pectinase, the enzyme activity of pectinase is 80U; let stand for 24 hours to balance the moisture in the tobacco leaves, and then adjust the moisture content of the tobacco leaves to 25%;

Embodiment 3

[0038] The method for preparing cigar tobacco leaves by pectinase fermentation comprises the following steps:

[0039] 1) Aging 30kg of the lower part of the cigar filler under natural conditions for one year, and then re-moisture the upper part of the smoke under vacuum conditions;

[0040] 2) dissolving pectinase in deionized water to obtain a pectinase solution, wherein the activity of pectinase in the pectinase solution is 600U / ml;

[0041] 3) placing the leaf stalk end of the remoisturized tobacco leaf in step 1) in the pectinase solution to soak the stalk for 10 minutes, and then spraying the pectinase solution on the tobacco leaves at a weight ratio of 1:10 to obtain tobacco leaves containing pectinase, wherein , in every gram of tobacco leaves containing pectinase, the enzyme activity of pectinase is 60U; let stand for 24 hours to balance the moisture in the tobacco leaves, and then adjust the moisture content of the tobacco leaves to 25%;

Abstract

The invention discloses a preparation method for cigar tobacco through the fermentation of pectinase. The preparation method comprises the steps that the petiole end of the tobacco which is retreated with moisture is placed into pectinase solution, the petiole is immersed for 10-30 min, then the pectinase solution spray is sprayed on the tobacco according to a weight ratio of 1:5-15, the tobacco containing the pectinase is acquired, and still standing is conducted, so that water balance of the tobacco can be achieved; the tobacco with the moisture content to be 24% to 26% is placed under the condition in which the temperature ranges from 47 to 53 DEG C and the humidity ranges from 65-75%, fermentation lasts for 10 to 60 days, and cigar tobacco is acquired. According to the preparation method for cigar tobacco through the fermentation of pectinase, the cigar tobacco is the study object, bitter taste of cigar acquired through fermentation is improved obviously, and improvement is presented in flavor character, smoke character, taste character, combustibility, gray score and quality.

Description

technical field [0001] The invention relates to the field of cigar processing, in particular to a method for preparing cigar leaves by fermentation with pectinase. Background technique [0002] Pectin is a hydrophilic colloidal substance, which plays a certain role in the hygroscopicity and elasticity of tobacco leaves through osmosis. Tobacco leaves with high pectin content are sensitive to changes in relative air humidity. When the relative air humidity is high, the tobacco leaves absorb moisture and become soft, and the natural heating phenomenon is intense, and even lead to mildew; when the air relative humidity is low, the tobacco leaves are dehumidified and harden. Become brittle and break easily. Pectin is an unfavorable chemical component for tobacco smoking quality. Pectin is fermented to produce as much as 1-1.5% acetic acid, which has a pungent and pungent taste. Pectin can produce methanol during the burning and smoking process, and methanol is further oxidize...
