Description
Technical field
The present invention relates to a kind of absorption liquid and a kind of method of discerning the flue gas taste.
Background technology
One of basic impression of the taste of flue gas is cigarette consumption person, so it is one of important indicator that influences cigarette quality and decision consumer hobby.And the planting environment of tobacco, processing technology and flavoring and casing technology etc. all have the influence of outbalance to cigarette quality, and are significant with the stable aspect that keeps product to the discriminating of tobacco brand or kind.For a long time, the evaluation of cigarette quality is mainly depended on sensory evaluation, yet because the difference of physiology such as the person of smokeing panel test is individual, sex and experience and psychology, the enough reliabilities of expression shortage of, sense of reality objective to taste; In evaluation procedure, need organize a large amount of personnel to be evaluated in addition, can't realize fast detecting.In addition, the tobacco of smokeing panel test in a large number, also very big to the able-bodied danger of the person of smokeing panel test, therefore make up and do not rely on the objective of the person's of smokeing panel test subjective judgement and detection system accurately, be a urgent and significant task.
In recent years, along with development of science and technology, particularly sensor is in the research of chemical field in recent years, and the detector that some are novel such as electronic tongue and Electronic Nose etc. begin to apply in the check of food flavor substances.2000, France Alpha MOS instrument company has released first commercialization electronic tongue Astree in the world, this electronic tongue can identify acid, sweet, bitter, salty taste more accurately, and provides the composition that its quantitative concentration can be used for analyzing fruit juice raw material.
At home and abroad, see about much more comparatively the utilization electronic tongue detects in Study on Flavor such as tealeaves and drinks, wherein Wu Jian etc. has done a kind of green tea Classification Study based on the electronic tongue technology, green tea is analyzed in the major component of the cyclic voltammetric signal of copper electrode, obtained distinguishing preferably effect.Liyama (2003) etc. utilizes taste sensor and glucose sensor array that the quality of sake is detected, this taste sensor array is made up of eight lipid membrane electrodes, utilize principal component analysis (PCA) to carry out pattern-recognition and dimensionality reduction, demonstrate the signal graph of bidimensional at last, represent titratable acidity and pol content respectively, had very big correlativity between the signal value output of electronic tongue and titratable acidity, the pol.
Yet the relevant research of electronic tongue aspect the identification of smoke of tobacco primary taste yet there are no report at home and abroad.
Summary of the invention
For set up do not rely on the objective of the person's of smokeing panel test subjective judgement and accurately detection system the smell road in the flue gas is discerned, one aspect of the present invention provides a kind of absorption liquid, wherein, this absorption liquid contains sodium carboxymethyl cellulose, sorbierite, KCl and NaCl, and with deionized water or ultrapure water preparation; General assembly (TW) with this absorption liquid is a benchmark, and the content of described sodium carboxymethyl cellulose is 0.5-1.5 weight %, and the content of described sorbierite is 2-4 weight %, and the content of described KCl is 0.1-0.14 weight %, and the content of described NaCl is 0.7-1 weight %.
The present invention also provides a kind of method of discerning the flue gas taste on the other hand, and wherein, this method comprises the steps:
(1) collects flue gas: carry out smoking with smoking machine, collect the flue gas at place that described smoking machine discharges with Fume collector and by the described absorption liquid of claim 1-3, acquisition contains the potpourri of flue gas, and wherein, every milliliter of this potpourri contains the flue gas that the burning of 0.04-0.3 gram cigarette is discharged;
(2) detect: the described potpourri that contains flue gas as in the electronic tongue pick-up unit, is used rinse agent rinse electronic tongue sensor, reading.
Experimental result shows when the method that adopts absorption liquid provided by the present invention and electronic tongue detects the taste of flue gas, the result who obtains is consistent with the result of existing taste by the person's of smokeing panel test evaluation of flue gas, but deviation is littler, approximately differ 10 times, thereby the taste that adopts the method for absorption liquid provided by the invention and electronic tongue to detect flue gas more can reflect the taste of flue gas accurately, objectively.
The method of identification flue gas taste provided by the invention is a kind of detection technique based on electronic tongue five tastes sensor, be that artificial intelligence machine is applied to once completely newly attempting in the identification of cigarette smoke primary taste, its purpose and meaning are to improve more effectively cigarette smoke primary taste objective evaluation result's accuracy, for artificial sensory evaluating smoking provides more objective and accurate reference frame, for the identification field that progressively artificial intelligence machine is applied to the cigarette smoke primary taste lays the foundation.
