Embodiment 1

[0022] Using near-infrared spectral analysis technology to non-destructively identify the authenticity of Yunyan (impression) cigarettes:

[0023] 1. Sample preparation: prepare genuine Yunyan (impression) cigarette samples, take 20 cigarettes from the same batch, and sample 1000 cigarettes in total for model building. The cigarettes were equilibrated for 24 hours at a temperature of 22±1°C and a humidity of 60%±2%, and the spectra of the sampled cigarettes were collected within one week of sampling.

[0024] 2. Spectral data collection: FT-NIR spectrometer (model Antaris, American Thermo Electric Company) was used to collect sample spectra. Spectral collection conditions are: spectral collection method: diffuse reflection of integrating sphere; scanning range (Data Range): 4000-10000cm -1 ;Resolution: 8cm -1 ; Number of scans: 30 times; Reference setting: use the gold-plated inner wall of the integrating sphere as the background, and the background spectrum must be collecte...

Abstract

The invention discloses a method for applying the near infrared spectral analysis technology for undamaged identification of the truth of tobacco. The method is as follows: firstly, spectrum data of true tobacco is acquired and stored into a computer; secondly, the method for qualitative analysis of the similarity matching in TQ analyst7.1 software is applied to establish a similarity matching model of the tobacco of the brand; thirdly, a similarity matching critical value of the tobacco of the brand is obtained after calculation. When the tobacco is identified, the same method is applied for acquiring spectrum data of the tobacco to be identified and calculating a spectrum similarity matching value of the tobacco to be identified; when the similarity matching value of the tobacco to be identified is more than or equal to the similarity matching critical value of the tobacco of the brand, the tobacco to be identified is identified to be true tobacco with the same brand, or else, the tobacco is false tobacco. The amount of samples required by the identification method is small; the identification process does not need pretreatment and sampling procedure, does not damage cigarettes and is simple, thereby the method is extraordinarily suitable for being promoted in the tobacco industry and the tobacco law enforcement and supervision department and has good market application prospect.

Description

technical field [0001] The invention belongs to the technical field of cigarette anti-counterfeiting, and in particular relates to a method for non-destructively identifying the authenticity of cigarettes by using near-infrared (NIR) spectral analysis technology. Background technique [0002] The counterfeiting of brand-name cigarettes is a social problem that has been banned repeatedly. The proliferation of counterfeit cigarettes in the market not only damages the interests of consumers, but also ruins the reputation and reputation of cigarette manufacturers, causing serious impact and harm to society. Therefore, cigarette counterfeiting is not only one of the important issues discussed and studied by cigarette manufacturers and tobacco law enforcement supervision departments, but also a topic of common concern to the majority of cigarette consumers. In the process of cracking down on counterfeit cigarettes, the most important thing is to be able to identify and identify co...
