Problems solved by technology

Although the uniformity of shredded cigarettes during processing can be evaluated by sensory evaluation or chemical composition analysis, the sensory evaluation method needs to prepare evaluation samples every time, and organize professional evaluators to conduct special evaluations, which requires a large workload And the requirements are high, it cannot be used as a daily monitoring method
The method of chemical composition analysis has many detection indicators, the detection time is long, and the detection results are greatly affected by the sugar and spices added by external sources. The requirements for sampling and detection process are very high. When individual indicators fluctuate greatly, the evaluation Therefore, it is impossible to evaluate the uniformity of processing comprehensively, clearly and quickly by analyzing the chemical composition of processed leaf shreds
At present, there is no good technical means to carry out normalized and precise monitoring and evaluation of the uniformity of the cigarette shredded production process

Embodiment 1

[0076] The present embodiment provides a method for monitoring the uniformity of leaf silk processing by DNA analysis, the steps are as follows:

[0077] (1) during the normal production of shredded tobacco leaves, after the drying process, every 5min, randomly carry out 10 samplings, and the samples taken each time are evenly divided into 4 parts, and the samples after the sampling are numbered;

[0078] (2) Roll one of the cut leaf samples into a cigarette sample as a cigarette sample for sensory quality evaluation, organize personnel qualified for sensory quality evaluation in accordance with GB 5606.4-2005 "Cigarette Part 4: Sensory Technical Requirements" Sensory quality evaluation of cigarette samples;

[0079](3) Carry out chemical composition analysis on a part of the obtained leaf silk samples, and the leaf silk samples are based on YC / T468-2013, YC / T 159-2019, YC / T 161-2002, YC / T 217-2007 and YC / T 31-1996 standard methods for the determination of total plant alkaloi...

Embodiment 2

[0095] The only difference from Example 1 is that in this example, in step (6), the average DNA concentration value of the leaf silk sample ±3 times the standard deviation is used as the DNA concentration monitoring interval, and the remaining steps and methods are the same as those in Example 1.

Abstract

The invention provides a method for monitoring tobacco shred processing uniformity through DNA analysis and application thereof, and the method for monitoring tobacco shred processing uniformity through DNA analysis comprises the following steps: carrying out DNA concentration detection on a tobacco shred sample meeting a standard, establishing a DNA concentration monitoring interval, and judging the processing uniformity of the tobacco shred sample. According to the method, detection of the DNA concentration is introduced into monitoring and evaluation of the processing uniformity of the cut tobacco, the processing uniformity of the cut tobacco can be accurately detected only by detecting the DNA concentration of the produced cut tobacco, and the method is high in stability, good in parallelism, low in detection cost and high in efficiency and has important application value in processing of the cut tobacco.

Description

technical field [0001] The invention belongs to the technical field of tobacco leaf silk processing, and in particular relates to a method for monitoring the processing uniformity of leaf silk through DNA analysis and its application. Background technique [0002] In recent years, with the promotion and development of my country's tobacco characteristic technology, the tobacco industry has higher and higher requirements for refinement in the production process of cigarettes, and more and more strict requirements for the stability and consistency of cigarette products. With the upgrading of cigarette product structure, consumers have higher and higher requirements for the quality and stability of cigarette products. The new situation has put forward new requirements for the production and processing of cigarette industrial enterprises. In order to achieve better development, enterprises must conduct in-depth research on the "homogenization" of cigarette production. [0003] ...
