Problems solved by technology

Patent CN104569263B uses purge and trap-gas chromatography-mass spectrometry to compare the similarity of the GC-MS chromatographic fingerprints of the reference batch of cigarette samples and the cigarette samples to be tested. The invention requires more than 10 batches of reference cigarette samples. The practical application is more difficult, and the requirements for the equipment are higher, and the operation is more complicated
[0005] To sum up, most of the existing detection technologies have defects such as high requirements for instruments and equipment, complex detection and data processing, and more and more stringent requirements for experimental samples and reagent consumables, which are not conducive to making accurate and objective evaluation conclusions on the quality stability of cigarette products

Embodiment 1

[0043] Embodiment 1. In this embodiment, the quality stability of batch B cigarette samples of the same brand specification is compared with the finished cigarettes of batch A of a certain brand specification as a reference. The specific operation includes the following steps:

[0044] (1) Sampling and pretreatment of finished cigarette samples

[0045]Batch A finished cigarettes were randomly selected 5 times, and Batch B finished cigarettes were randomly selected 2 times, and 2 boxes were randomly selected each time, each time as a sample. Open the small box packaging of each sample, peel off the cigarette paper and filter, take out the shredded tobacco in the cigarette, mix it evenly and place it in a constant temperature and humidity room with a temperature of (22±1)°C and a relative humidity of (60±2)%. Environment equilibrated for 48 hours standby.

[0046] (2) Thermogravimetric analysis of finished cigarette samples

Embodiment 2

[0068] Example 2. In this example, the quality stability of the batch C cigarette samples of the same brand specification was compared with the finished cigarettes of batch A of a certain brand specification as a reference. The specific operation includes the following steps:

[0069] (1) Sampling and pretreatment of finished cigarette samples

[0070] Batch A finished cigarettes were randomly selected 5 times, and Batch C finished cigarettes were randomly selected 2 times, and 2 boxes were randomly selected each time, each time as a sample. Open the small box packaging of each sample, peel off the cigarette paper and filter, take out the shredded tobacco in the cigarette, mix it evenly and place it in a constant temperature and humidity room with a temperature of (22±1)°C and a relative humidity of (60±2)%. Environment equilibrated for 48 hours standby.

[0071] (2) Thermogravimetric analysis of finished cigarette samples

[0072] Grind each balanced cigarette sample throu...

Abstract

The invention discloses a method for evaluating the quality stability of product cigarettes among batches for judging the quality stability of product cigarettes among batches and specifications of same brand. The method is characterized by comprising the following steps: extracting the product cigarettes of two batches of same brand and specification as a reference sample and a to-be-tested sample; and judging the quality stability of the to-be-tested sample relative to the reference sample by comparing thermal weight loss TG curves of the reference sample and the to-be-tested sample. A thermal gravimetric analyzer is used for judging the quality stability of product cigarettes among batches. By comparing the similarity of the thermal weight loss curves of the reference sample and the to-be-tested sample, a concept of thermal weight loss curve similarity threshold value is introduced for the first time as a judging ground of the quality stability of product cigarettes among batches, thereby providing a feasible method for judging the quality stability of product cigarettes among batches. The used equipment and operations are simple, no chemical reagents are used, the amount of needed samples is small, and the experimental result is objective and accurate.

Description

technical field [0001] The invention relates to a method for evaluating the quality stability of finished cigarettes, belonging to the technical field of tobacco product quality evaluation. Background technique [0002] With the increasingly fierce competition in the cigarette product market and the increasing automation of industrial production, objective and accurate monitoring of product quality stability is of great significance for the maintenance and improvement of cigarette product quality. [0003] At present, the tobacco industry’s monitoring methods for the quality stability of finished cigarettes mainly include the sensory evaluation of cigarettes, the detection of relevant components of mainstream smoke of cigarettes, such as the detection of conventional components of mainstream smoke of cigarettes and the detection of seven harmful components. In addition, the industry has also applied for a number of invention patents in this field. Among them, the patent CN1...
