Embodiment 1

[0032] Embodiment 1: Existing method handles shredded tobacco leaf stalks (abbreviation alkali-oxygen treatment)

[0033] Take cut stems of a certain quality, spray and add 10% ammonia water in a mass ratio of 5: 1 (cut stems: ammonia water), and add 10% ammonia water in a mass ratio of 7: 1 (cut 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 3:1 (stem: citric acid), and dried at 40°C.

Embodiment 2

[0034] Embodiment 2: the method of the present invention handles shredded tobacco leaf stems

[0035] Take cut stems of a certain quality, spray and add 1.5% ammonia water in a mass ratio of 15: 1 (cut stems: ammonia water), and add 1.5% ammonia water in a mass ratio of 7: 1 (cut stems: H 2 o 2 ) proportional spraying with 3% H 2 o 2 , placed in a constant temperature oven at 40°C for 3 hours, sprayed with 5% citric acid at a ratio of 5:1 (stem: citric acid), and dried at 40°C.

[0036] Accurately weigh 100 g of the above-mentioned processed cut stems, spray and add compound enzyme liquid (containing 0.5% amylase, 0.5% protease, and 0.5% cellulase) in a mass ratio of 10:1 (stem cut: compound enzyme liquid) , placed in a constant temperature oven at 30°C for 4 hours, then raised the temperature to 85°C for 4 hours to inactivate the enzyme to terminate the reaction.

Embodiment 3

[0037] Embodiment 3: the method of the present invention handles shredded tobacco leaf stems

[0038] Take cut stems of a certain quality, spray and add 15% ammonia water in a mass ratio of 5: 1 (cut stems: ammonia water), and add 15% ammonia water in a mass ratio of 2: 1 (cut stems: H 2 o 2 ) proportional spraying and adding 15% H 2 o 2 , placed in a constant temperature oven at 80°C for 2 hours, sprayed with 15% citric acid at a ratio of 15:1 (stem: citric acid), and dried at 40°C.

[0039] Accurately weigh 100 g of the above-mentioned treated cut stems, spray and add a compound enzyme solution (containing 3% amylase, 3% glucoamylase, and 3% hemicellulase) in a mass ratio of 5:1, and place in a constant temperature oven at 60°C. Leave the reaction for 1 hour, raise the temperature to 95°C and leave it for 1 hour to inactivate the enzyme to terminate the reaction.

Abstract

The invention relates to the field of tobacco, in particular to a method for treating cut stems of tobacco leaves. The method comprises the steps of reducing the content of cell wall substances through H2O2 and ammonia, improving the reactivity of the cut stems with an enzyme, further utilizing the compound enzyme for catalytic degradation of proteins, starch, cellulose and other macromolecules, generating an aroma precursor, sugar and amino acids and further generating aroma substances by further decomposition. The adoption of the method for treating the cut stems can improve the filling value by 27.6%, improve the sugar / nicotine ratio by 49.5% and reduce the content of the cell wall substances by 42.3%, and the analysis of main aroma components shows that the total content of the aroma components is improved by 25.7%, wherein the content of Maillard reaction products is improved by 140.5%, and the content of carotenoid degradation products is improved by 115.6%. The sensory evaluation shows that the effects of reducing wood flavor, reducing irritation, increasing aroma quantity and leading the smoke to be coordinated and thicker can be realized after the treatment of the cut stems of the tobacco leaves by using the method, indicating that the method has good application prospect in the tobacco 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. Due to their high cellulose content and low sugar and alkali components, tobacco stems are usually used as shredded stems or made into thin sheets to increase the filling value of cigarettes. It is beneficial to reduce coke, which is also one of the main ways to utilize tobacco stems. However, the content of cell wall substances in tobacco stems is large, the aroma is poor, and the taste is flat, which will bring many adverse effects to the smoke. The more high-end cigarettes, the smaller the proportion of tobacco stems used, which limits the use of tobacco stems in the cigarette industry. . [0003] In recent years, research on tobacco stems at home and abroad has achieved results. Zhou Yuanqi...
