Description
Technical field
The invention belongs to tobacco preparing technical field, be specifically related to a kind of stem usability evaluation method in cigarette preparation process.
Background technology
In cigarette preparation process, often relate to the availability concept of tobacco material, its implication mainly pursues the maximum using of tobacco material.Specifically, availability is an aggregate concept, and from the angle of industrial application, it is exactly the industrial use value often said.For cigarette industry, the requirement of availability mainly comprises following aspect: the cigarette got consumer reception 1. making high-quality, and fragrance can be kept to stablize; 2. can adapt to Cigarette processing process, consume few, silk production rate is high, and cost is low; 3. security is good, meets the regulation about health each side and requirement.
But it should be explicitly made clear at this point, the availability of tobacco material is not equal to the quality of tobacco material.For tobacco stem shred and tobacco leaf cut tobacco, the principal ingredient of stem is cell wall substance (content about 40%), and comprise cellulose, hemicellulose, lignin and pectin etc., the flavor matter included is less.Because its processibility is better, thus there is good availability, but due to flavor matter content in stem less, its tobacco quality of cigarette that thus stem addition is larger, suction mouthfeel are relatively also poor.Thus, conventional in prior art tobacco leaf usability and the decision method of quality are not also suitable for the usability evaluation of offal and stem.
In prior art, stem can be divided into sheet stalk, microwave granule peduncle by different processes standards, and become silk stalk etc., due to the difference of processes mode, between the physics between them, sense organ, smoke components, difference is also larger.But the no matter stem of which kind of processing mode, the factor affecting its availability mainly contains physical appearance (comprising gloss/oil content, Filling power), aesthetic quality, harmful ingredients in flue gas (the seven kinds of harm compositions comprising tar and be representative with carbon monoxide etc., seven kinds of harm composition sizes often characterize with harmfulness index) etc.In existing stem appraisement system, separate between these factors, its value is not identical yet, is therefore difficult to compare the influence degree to quality between Different factor, even if same factor, is difficult to the difference degree compared intuitively between different sample yet.At present when evaluating stem availability, often can only pay close attention to wherein one or two factor, the availability condition of stem can't be assessed comparatively intuitively, all sidedly.
What is more important, in existing cigarette composition, the availability of tobacco material is dynamic change, and it is respective change along with product demand change, and same stem sample availability in A cigarette product is higher, but availability may be just lower in B product.Such as, the more focus of low grade products is at the gloss/oil content of stem and Filling power, and the more focus of expensive goods is at aesthetic quality, releasing content of coke tar and harmfulness index.Thus for tobacco stem shred, for different cigarette compositions, the weighted value affecting the factor of offal availability is also different, and still lacks a kind of evaluation method comparatively comprehensively can evaluating tobacco stem shred availability preferably in prior art.
Summary of the invention
The object of the invention is to provide a kind of stem usability evaluation method, thus can the comparatively comprehensive availability to stem make accurately and the evaluation of science, thus provides good reference value and accurate foundation for cigarette composition work.
The technical solution used in the present invention is as follows.
A kind of stem usability evaluation method, for cigarette composition work, for the stem sample of certain batch of separate sources, different situations, the method specifically comprises the following steps:
(1) determine the original score value of each factor affecting stem availability, the described factor affecting stem availability comprises: gloss-oil content, aesthetic quality, Filling power, releasing content of coke tar and harmfulness index;
The original score value unit record of wherein said gloss-oil content is for dividing, and gloss score value is given a mark according to the requirement of gloss in national standard " technical requirement of GB 5606.6-2005 cigarette the 4th part sense organ ", full marks 5 points; Oil content score value according to being corresponding score value to grade that oil content is determined in " GB 2635-1992 flue-cured tobacco ", full marks 5 points; Gloss-oil content is gloss score value and oil content score value sum; Gloss-oil content score value is for hoping large value, and numerical value is more high better, but the setting of total score does not affect final result of determination;
The original score value unit record of aesthetic quality is for dividing, and score value detects according to the single-tobacco-typed cigarette evaluation method required in existing industry standard " YCT 138-1998 tobacco and tobacco product sensory evaluation method "; Aesthetic quality's score value is for hoping large value, and numerical value is more high better, but the setting of total score does not affect final result of determination;
The original score value of Filling power is actual measured value, and the mensuration according to industry standard " YCT 152-2001 cigarette shreds Filling power " detects; Filling power unit is cm
3/ g; Filling power is for hoping large value, and numerical value is more high better, and the setting of unit does not affect final result of determination;
