Description
Technical field
The invention belongs to tobacco manufacture field, relate to a kind of processing method that improves cut stem quality.
Background technology
The features such as stem has tar, nicotine content is low, and filling capacity is good, are one of main filler of cigarette tobacco leaf formulation, in cigarette composition, play an important role.Under product design allows, increase stem consumption, be one of important means of reducing tar and reducing harm, be also cost-saving good method.Stem is processed by offal, but owing to containing the macromolecular substances such as a large amount of celluloses, pectin and lignin in offal, these macromolecular substances are the restraining factors that improve cut stem quality.Conventional machining process technology cannot make these macromolecular substances fully be degraded, can not control the palliating degradation degree of these macromolecular substances, finished product stem exists on sense organ stimulates the shortcomings such as large, concentration is high, assorted gas is obvious, by reinforced, can only cover its shortcoming, and effect is limited, cannot be from dealing with problems in essence, the application in cigarette composition is restricted.
Technical staff is carrying out a large amount of research work improving aspect stem comprehensive quality in recent years, mainly contains the following aspects: the application of (1) novel technique, adopt new technology, new technology improves stem quality.For example, the people such as He Ju adopt microwave expansion offal, offal after microwave expansion aspect the relative amount of aroma component, organic acid etc. all to being significantly improved same as before, suction taste improves, and interior quality is improved, and filling capacity improves, comprehensive quality promotes (He Ju, Liu Weijuan etc. to some extent, < < tobacco science and technology > >, the 2nd phase in 2006, the research of microwave expansion tobacco stalk quality).(2) chemical treatment, by the quality of the some chemical properties raising stem in solvent extraction or extraction offal or stem.For example, the people such as Li Jun make stem after utilizing spirit solvent to extract offal, and the furfural after this technical finesse in stem, 5 methyl furfural and phenmethylol etc. obviously reduce the disadvantageous chemical composition of aesthetic quality, and stem interior quality is improved.(3) process optimization, by technological process reproduce, technology optimization etc. improves stem quality.For example, patent ZL200910065889.0 discloses a kind of technology and equipment of cabo shredding, and offal, through operations such as immersion, Terrier Storage, steaming stalk, row's stalk, pressure stalk, row's stalk sheets, is reduced to stem to make broken, the stem of making is close with cut tobacco shape, improves the use value of stem; Patent ZL200810154171.4 discloses a kind of cut rolled stem processing procedure, offal through warming and humidifying, cut stalk, stem warming and humidifying, stem expansion, cut the operations such as stem, offal, through twice cutting, has improved stability and the use value of stem quality.(4) biotechnology is processed, and utilizes complex enzyme or microorganism to degrade to the macromolecular components such as cellulose in offal or stem, improves the quality of stem.For example, the people such as Lin Xiang adopt complex enzyme to process stem, the products relevant to aesthetic quality such as the total sugar content after processing in stem, mailland reaction product, carotenoid catabolite are all improved, stem flavouring essence quality make moderate progress (Lin Xiang, Tao Hong, Shen Guanglin etc., < < Agriculture of Anhui science > >, the 4th phase in 2011, utilize the research of compound enzyme improved cabo quality).
In a word, although the research in the recent period cut stem quality being improved is more, the lifting effect of cut stem quality is bad.Some novel technique energy consumptions are high, and brought potential safety hazard (as microwave leakage etc.), be unfavorable for production application, and chemical treatment method easily causes secondary pollution, and cost is higher, commercial Application difficulty, during biotechnology is processed, due to cellulose in offal, the biomass components such as pectin are to wrap up in order existence, and the activity between different biologic products can suppress mutually, the disposable of biologic product directly adds, cannot well to offal inside, need degradable component effectively to process, degradation effect is bad, and all to degrade online, be stored as master, not through off-line storage alcoholization, produce fragrant effect bad, quality improving is not obvious, need to adopt classification biological treatment, after processing, alcoholization is produced fragrant, could obviously improve cut stem quality.
