Method for quickly and accurately evaluating quality stability of cigarette product

Abstract

The invention discloses a method for quickly and accurately evaluating the quality stability of a cigarette product. The method comprises the steps of collecting GC-MS chromatograms of more than 10 batches of cigarette products which have the same brand specification as that of the cigarette product to be detected and are purchased in the proper way by a purge trap-gas chromatography-mass spectrometer combination method, and averagely acquiring a chromatograph fingerprint of the cigarette of the brand specification by stacking; collecting the GC-MS chromatograms of a batch of cigarette samples to be detected, and analyzing the similarity between the GC-MS chromatograms of a batch of cigarette samples to be detected and the chromatograph fingerprint of the cigarette of the brand specification by a relevant coefficient method, and judging the cigarette products with the similarity being greater than or equal to 90 percent to be cigarette products with stable quality and the cigarette products with the similarity being smaller than 90 percent to be cigarette products with unstable quality. The method has the advantages of simplicity in operation treatment, high spectrum specificity, quickness and accuracy in conclusion making, and the like.

Description

technical field [0001] The invention relates to a method for evaluating the quality stability of cigarette products, belonging to the technical field of tobacco product quality evaluation. Background technique [0002] Cigarettes are bulk fast-moving consumer goods. Maintaining long-term stability of product quality and style is of great significance for enterprises to maintain consumer loyalty and increase market share. However, with the continuous deepening of market-oriented reforms in the tobacco industry, the concentration of domestic cigarette brands is getting higher and higher, and the annual output of single-brand cigarettes is mostly hundreds of thousands of boxes, and some even reach millions of boxes. How to ensure the uniform quality between batches of the same brand of cigarette products has become the focus of the enterprise's product quality control work. [0003] At present, the tobacco industry has applied for a number of invention patents. Among them, pa...

AI Technical Summary

Problems solved by technology

Due to problems such as interrelationship and mutual restriction among nearly a hundred parameter indicators stipulated in the national standard of "Cigarette", it is unscientific to simply select a certain parameter index or a group of parameter indicators to inspect and evaluate product quality stability, and misjudgments are prone to occur. and omissions

At the same time, the existing technology has a large workload in the early stage of detection and complex data processing in the later stage, which is not conducive to making a fast, accurate and objective evaluation conclusion on the quality stability of cigarette products
