Problems solved by technology

[0004] Among the above methods, the focus is on a single indicator of reconstituted tobacco leaves, and the detection workload is large, the data processing is complicated in the later stage, and many instruments and reagents are involved. At the same time, some indicators have certain subjectivity.
More importantly, none of these methods can fully characterize the quality characteristics of reconstituted tobacco leaves, and they do not involve the evaluation of product batch-to-batch quality stability

Embodiment 1

[0042] Example 1. In this example, the quality stability of batch B reconstituted tobacco samples of the same brand specification was compared with batch A reconstituted tobacco leaves of a certain brand specification as a reference. The specific operation includes the following steps:

[0043](1) Sampling and pretreatment of reconstituted tobacco samples

[0044] The reconstituted tobacco leaves of Batch A were randomly drawn 5 times, and the reconstituted tobacco leaves of Batch B were randomly drawn 2 times, 10 g were randomly drawn each time, each time as a sample. Place each sample in a constant temperature and humidity environment at (22±1)°C and a relative humidity of (60±2)% for 48 hours for standby;

[0045] (2) Thermogravimetric analysis of reconstituted tobacco samples

[0046] Grind each balanced reconstituted tobacco leaf sample through a 40-mesh sieve, weigh (10 ± 1) mg, place it in an alumina crucible of a thermogravimetric analyzer, and perform a thermal anal...

Embodiment 2

[0062] Example 2. In this example, the quality stability of batch C reconstituted tobacco samples of the same brand specification was compared with batch A reconstituted tobacco leaves of a certain brand specification as a reference. The specific operation includes the following steps:

[0063] (1) Sampling and pretreatment of reconstituted tobacco samples

[0064] The reconstituted tobacco leaves of Batch A were randomly drawn 5 times, and the reconstituted tobacco leaves of Batch C were randomly drawn 2 times, 10 g were randomly drawn each time, each time as a sample. Place each sample in a constant temperature and humidity environment at (22±1)°C and a relative humidity of (60±2)% for 48 hours for standby;

Abstract

The invention discloses a method for evaluating the quality stability of batch-to-batch reconstituted tobacco, and is used for judging the quality stability of batch-to-batch reconstituted tobacco ofsame brand and specification. The method is characterized by comprising the following steps: taking two batches of reconstituted tobacco of same brand and specification as a reference sample and a sample to be tested respectively, and judging the quality stability of the sample to be tested relative to the reference sample by contrasting the thermal weight loss TG curve of the reference sample andthe thermal weight loss TG curve of the sample to be tested. According to the method, a thermal gravimetric analyzer is used for judging the quality stability of batch-to-batch reconstituted tobacco,the similarity of the thermal weight loss curve of the reference reconstituted tobacco sample and the thermal weight loss curve of the reconstituted tobacco sample to be tested is compared, the similarity threshold value of the concept thermal weight loss curve is firstly introduced as the judgment basis of the quality stability of batch-to-batch reconstituted tobacco, and a feasible method is provided for judging the quality stability of batch-to-batch reconstituted tobacco; the equipment and operation processing used in the invention are simple, no chemical reagent does not need to be used,the quantity of required sample 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 reconstituted tobacco leaves, belonging to the technical field of tobacco product quality evaluation. Background technique [0002] Reconstituted tobacco leaf refers to a sheet or shredded regenerated product made of waste tobacco stems, tobacco powder, and shredded tobacco chips during cigarette processing, which is used as a cigarette filler. Adding an appropriate amount of reconstituted tobacco leaves to cigarettes can adjust and improve the physical properties and chemical components of cigarettes according to people's wishes or requirements to a certain extent, thereby contributing to the improvement of the internal quality of cigarettes and is one of the ways to reduce the harmful components of tobacco. An important technical measure. [0003] At present, the tobacco industry judges the quality of reconstituted tobacco leaves mainly from four aspects: sensory evaluation, s...
