Problems solved by technology

Therefore, the softening time of the tobacco stems is too long, generally more than 6-8 hours
[0007] 3. The existing tobacco stem silk making process is mainly based on the steam expansion process. The chemical composition of the expanded tobacco stem is not much different from that before expansion. Except for a slight decrease in total sugar and nicotine, its total nitrogen, total cell wall matter and lignin content The content is basically unchanged, and the improvement of the smoking quality of the tobacco stem material due to expansion is mainly due to the change of its physical structure, while the woodiness and irritation of the tobacco stem itself have not disappeared and improved, and the internal quality has not been greatly improved.
However, the application of these technologies will inevitably lead to the reduction of flavor substances in cigarettes, the fragrance will be weak, and the taste will be worse.
Therefore, while reducing cigarette tar, it is impossible to maintain a considerable flavor and become a bottleneck restricting the development of low-tar cigarettes.

Embodiment 1

[0026] Stem washing: set up a transmission device in the stem washing tank, so that the tobacco stems and washing water flow relatively (the speed is controlled at 0.2m / s), the mass ratio of tobacco stems and washing water is 1:20, and the washing water contains quite 0.2% stem-washing complex enzyme (composed of 50% pectinase and 50% xylanase) in the mass of tobacco stems, 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.

[0027] Stem pressing and cutting: before pressing and cutting, the tobacco stems are heated and the tobacco stems are cooled respectively.

[0028] (3) Fragrance enhancement reaction of shredded stems:

[0029] Configure feed liquid and aromatizing compound enzyme:

[0030] Feed liquid: 1 part by weight of glucose, 1 part by weight of fructose, 0.05 part by weight of alanine, and 0.05 part...

Embodiment 2

[0035] Sample 0 (control group): as in Example 1, but the stem washing compound enzyme used is: 30% pectinase, 30% hemicellulase and 40% cellulase; the substance contained in the feed liquid is: 2 parts by weight Glucose, 2 parts by weight of alanine; the addition of flavoring compound enzyme is equivalent to 3% of the cut stem quality.

[0036] Sample 1: As in Example 1, but the aroma-enhancing compound enzyme used therein is trypsin: medium temperature α-amylase: cellulase: hemicellulase = 1:1:2:1. Cellulase is enzymatic activity FPA>18,000 u / ml (Trichoderma viride), hemicellulase is food grade, purchased from Ningxia Xiasheng Company); feed solution 1 is: 1 part by weight of glucose, 1 part by weight of fructose and 0.05 parts by weight of alanine and 0.05 parts by weight of proline.

[0037] Sample 2: Same as sample 1, but the feed liquid is composed of feed liquid 2, namely: 1 part by weight of glucose, 0.5 part by weight of fructose, 0.03 part by weight of alanine, and 0....

Abstract

The invention provides a tobacco stalk processing method for enhancing fragrance by tobacco stalks and relates to the field of cigarette processing. The tobacco stalk processing method is characterized by comprising the following steps of (1) stalk washing enzymolysis treatment: during the stalk washing, tobacco stalks and stalk washing water relatively flow, the mass ratio of the tobacco stalks to the stalk washing water is 1:(10-100), stalk washing compound enzyme with the mass being 0.05 to 5 percent of the tobacco stalks is added into the stalk washing water, and the stalk washing compound enzyme consists of 30 to 70 percent of pectinase and 70 to 30 percent of xylanase through being metered in percentage by mass; (2) stalk pressing and stalk shred cutting; and (3) stalk shred fragrance enhancing reaction: 1 to 5 percent of material liquid and 0.1 to 1 percent of fragrance enhancing compound enzyme through being metered by the weight of the stalk shreds are added into the stalk shreds, the reaction is carried out, the material liquid contains glucose, fructose, alanine and proline, and the fragrance enhancing compound enzyme consists of protease, amylase, cellulose and pectinase. The stalk washing enzymolysis process and the stalk shred fragrance enhancing reaction process are organically integrated into the tobacco stalk processing process, and the continuous on-line treatment on a production line is realized. The fragrance of produced stalk shreds is improved, and in addition, the efficiency of the production line is improved.

Description

technical field [0001] The invention relates to the field of tobacco, in particular to a method for processing tobacco stems. 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 washing process, the cleaning rate o...
