A method for non-destructive and rapid identification of genuine and counterfeit cigarettes using infrared spectroscopy

Abstract

The invention discloses a lossless rapid method for discriminating true and false cigarettes by applying infrared spectroscopy technology. The method comprises: establishing a true cigarette standard infrared spectroscopy database and setting QC value thresholds; performing scan test on different discrimination points of cigarette materials used by a to-be-tested cigarette sample by infrared spectroscopy so as to obtain the infrared spectroscopy data of each discrimination point; retrieving corresponding true cigarette infrared spectroscopy data from the true cigarette standard infrared spectroscopy database, and calculating the QC value of each discrimination point between the two data; and deciding that the target sample is false cigarette if the QC value of any one discrimination point of the to-be-tested cigarette is lower than the set threshold, or else, deciding that the target sample is true cigarette. By employing the discrimination method provided by the invention, the cigarette sample is not damaged after detection and can be reused; the test time of each discrimination point is about 1 min, and consequently each cigarette sample can be detected in 8-10 min; and also the method is strong in specialization property and high in accuracy.

Description

technical field [0001] The invention belongs to the field of qualitative identification of tobacco products, in particular to a method for non-destructive and rapid identification of genuine and fake cigarettes using infrared spectrum technology. Background technique [0002] In recent years, with the implementation of the "Framework Convention on Tobacco Control", the domestic cigarette sales market has always been in a state of tight supply and demand, which provides an opportunity for the manufacture and sale of counterfeit cigarettes. As a result, the country and tobacco industry and commerce enterprises have suffered huge economic losses, seriously affecting the legitimate rights and interests of consumers, and to a certain extent, restricting the sustainable, stable and healthy development of the tobacco industry. [0003] At present, it has become one of the main responsibilities of provincial tobacco quality inspection agencies across the country to quickly and accur...

AI Technical Summary

Problems solved by technology

[0004] The sensory identification method mainly has the following disadvantages: First, the degree of imitation of counterfeit cigarettes gradually increases, making identification more difficult

Second, the sensory identification method has empirical limitations and subjectivity

The third is that the original records of the sensory identification method are mainly descriptive language, and there is a certain degree of scientific and authoritative congenital deficiency in the conclusion.

The target test objects of these methods are shredded cigarettes, which need to destroy the cigarette sticks, take out the shredded tobacco samples and then perform more complex pretreatment methods such as grinding, extraction or headspace enrichment, solid-phase microextraction, etc., and the visual discrimination effect is poor. It requires very tedious analysis and processing of test data, long test cycle, and large investment in equipment, which is not conducive to popularization and application in tobacco statutory quality inspection institutions
