Problems solved by technology

The former step is cumbersome. It needs to extract and separate the tobacco fiber raw material first, then carry out alkali oxygen treatment on the fiber part, and then separate it. Reduce the pleasure of smoking; the peroxidase in the ligninase used in the latter is expensive, the source is scarce, and it does not degrade the hemicellulose and pectin that are more abundant in the cell wall of tobacco stems

Embodiment 1

[0026] Embodiment 1: Existing method handles shredded tobacco leaf stalks (abbreviation alkali-oxygen treatment)

[0027] Take cut stems of a certain quality, spray and add 10% NaOH solution according to the mass ratio of 5:1 (stems: NaOH solution), and add 10% NaOH solution according to the mass ratio of 7:1 (stems: H 2 o 2 ) proportional spraying and adding 10% H 2 o 2 , placed in a constant temperature oven at 60°C for 2 hours, sprayed with 10% citric acid at a ratio of 5:1 (stem: citric acid), and dried at 40°C.

Embodiment 2

[0028] Embodiment 2: the method of the present invention handles shredded tobacco leaf stems

[0029] Take cut stems of a certain quality, spray and add 0.5% NaOH solution in a mass ratio of 5:1 (stems: NaOH solution), and add 0.5% NaOH solution in a mass ratio of 7:1 (stems: H 2 o 2 ) proportional spraying and adding 0.3% H 2 o 2 , placed in a constant temperature oven at 85°C for 2 hours, sprayed with 15% citric acid at a ratio of 5:1 (stem: citric acid), and dried at 50°C.

[0030] Accurately weigh 100 g of the above-mentioned cut cut stems, spray the cell wall enzyme solution (containing 0.5% cellulase, 0.5% hemicellulase, and 0.5% pectinase) according to the mass ratio of cut stems to 5:1, and keep the temperature at 60°C. The reaction was placed in an oven for 1 hour, and the temperature was raised to 95°C for 1 hour to inactivate the enzyme to terminate the reaction.

Embodiment 3

[0031] Embodiment 3: the method of the present invention handles shredded tobacco leaf stems

[0032] Take cut stems of a certain quality, spray and add 15% NaOH solution according to the mass ratio of 15: 1 (stems: NaOH solution), and add 15% NaOH solution at a mass ratio of 2: 1 (stems: H 2 o 2 ) proportional spraying and adding 10% H 2 o 2 , placed in a constant temperature oven at 45°C for 4 hours, sprayed with 15% citric acid at a ratio of 15:1 (stem: citric acid), and dried at 30°C.

[0033] Accurately weigh 100 g of the above-mentioned processed cut stems, spray the cell wall enzyme solution (containing 3% pectinase, 3% cellulase, and 3% hemicellulase) in a mass ratio of 10:1 to the cut stems, The reaction was placed in a constant temperature oven at 30°C for 4 hours, and the temperature was raised to 85°C for 4 hours to inactivate the enzyme to terminate the reaction.

Abstract

The invention relates to the field of tobacco, and in particular discloses a method for processing tobacco leaf cut stems. In the method, the content of cell wall substances is reduced and the reactivity of the cut stems and enzyme is improved through 0.3 to 10 percent H2O2 and 0.5 to 15 percent NaOH processing; cellulose, hemicelluloses and pectin are catalytically degraded by using cell wall enzymes; and the tested filling value after processing is improved by 21.2 percent, the ratio of sugar to nicotine is improved by 44.3 percent, and the content of the cell wall substances is reduced by 46.8 percent. The sensory evaluation proves that, after the tobacco leaf cut stems are processed by the method, the wood smell of the tobacco leaf cut stems is reduced, foreign smell is reduced, the irritation is reduced, the smoke is coordinated and a little thick; and the method is advantageous to increase the aromatic amount and improve the sensory feeling by applying the method to a flue-curedtobacco formula, and has good application prospect in the cigarette industry.

Description

technical field [0001] The invention relates to the field of tobacco, in particular to a method for processing shredded tobacco stems. Background technique [0002] Tobacco stems account for about 30% of the total tobacco leaves and are the main by-products of the tobacco industry. They are usually used as shredded stems or made into thin slices to increase the filling value of cigarettes, which is conducive to reducing coke. This is also one of the main ways to utilize tobacco stems . However, due to the low content of sugar and alkali in tobacco stems, high content of cell wall substances such as cellulose, poor aroma, and flat taste, it will bring many adverse effects to the smoke. The more high-end cigarettes, the smaller the proportion of tobacco stems used. The use of tobacco stems in the cigarette industry is limited. [0003] In recent years, some modification studies have been done on these shortcomings of tobacco stems at home and abroad. The patent of British Am...
