Problems solved by technology

However, since the process of making tobacco stems into shredded stems includes processes such as washing, storing, and moistening stems, and then pressing and cutting stems, etc., if the enzymatic hydrolysis process is added before washing stems, it will make the tobacco The time required for the stalk production process is further extended. Using the existing method, the entire treatment process takes more than 8 hours, which not only consumes the storage space of the production line; Complicated, which limits the effective application of this method in the production of shredded tobacco stems

Embodiment 1

[0028] Stem washing: install a transmission device in the stem washing tank so that the tobacco stems and the washing water flow relative to each other at 0.15m / s, the mass ratio of the tobacco stems to the washing water is 1:20, and the washing water contains 0.2 % stem-washing compound enzyme (composed of 50% pectinase and 50% xylanase), and the water temperature was kept at 55°C during the stem-washing process. After washing the stems, the tobacco stems are further subjected to primary storage, moistening and secondary storage for a total of 4 hours.

[0029] Stem pressing and cutting: before pressing and cutting, the tobacco stems are heated and the tobacco stems are cooled respectively. The temperature is increased by HT, and the steam flow rate is controlled to make the temperature of the tobacco stem 45-55°C, which is lower than the 70°C of the conventional process.

Embodiment 2

[0037] The shredded stems of sample No. 1 were used as a control test, using one-step enzymatic hydrolysis, and the enzymes used were 30% pectinase + 40% hemicellulase + 30% cellulase. The test results are shown in Table 2.

Embodiment 3

[0041] After the No. 1 sample of Example 1 was subjected to two-step enzymatic hydrolysis treatment, it was subjected to sensory evaluation, and compared with the untreated control shredded stem. The results are shown in Table 3.

Abstract

The invention relates to the field of cigarette processing, and discloses a tobacco-stem processing method for extracting fragrance by utilizing tobacco stems. The method comprises the following steps of: (1) stem-cleaning enzymolysis treatment: in stem cleaning, the tobacco stems and the stem cleaning water flow relatively; the mass ratio of the tobacco stems and the stem cleaning water is 1:10-100; stem-cleaning compound enzyme with the mass being 0.01-0.5% of that of the tobacco stems is added into the stem cleaning water, and the compound enzyme comprises pectinase with the mass fraction being 30-70% and xylanase with the mass fraction being 70-30%; (2) the stems are pressed and cut into stem silks; and (3) secondary enzymolysis treatment: hydrolyzed compound enzyme with the weight being 0.01-0.5% of that of the stem silks is added in the stem silks, and reaction is carried out for 0.5-2h; the hydrolyzed compound enzyme comprises protease, amylase, cellulose and hemicellulase with the weight ratio being 5-1:1:2:1. The method provided by the invention has the advantages that a part of cell wall materials can be effectively removed, the coordination of chemical components is achieved, the loss of aroma components in the soaking and enzymolysis process also can be avoided and the odor-absorbing effect is effectively improved.

Description

technical field [0001] The invention relates to the field of tobacco, in particular to an enzymatic hydrolysis method in the process of tobacco stem processing. Background technique [0002] Although tobacco stems are a component of tobacco, their physical and chemical properties are quite different from those of tobacco leaves. The sugar content of tobacco stems is low, and the content of nicotine and aroma substances is lower, which is about 20-25% of the leaves. These differences cause the tobacco stems to be poor in aroma, flat in taste, heavy in woodiness, and highly irritating, which limits the application of shredded stems. [0003] At present, the conventional treatment process of tobacco stems is as follows: [0004] Stem washing → heating of tobacco stems → storage of stems → heating of tobacco stems → pressing of stems → shredding of stems → feeding of shredded stems → puffing and drying of shredded stems → winnowing → storage. [0005] 1. In the existing stem w...
