Patent application number 200810073664.5 discloses a method for judging the moderate fermentation of black tea by the colorimetric value of theaflavins, but tobacco leaves do not contain this component, and the principles of black tea fermentation and tobacco leaf alcoholization are not consistent, so it cannot be used to judge the quality of tobacco alcoholization
Patent application number 201710034735.X discloses a quantitative detection method for the color of traditional Chinese medicine injections. It can be judged by the color whether the traditional Chinese medicine injections have deteriorated. Traditional Chinese medicine preparations do not need to be alcoholized, and their quality will gradually decline over time, while the first-cured tobacco leaves need to be alcoholized to improve tobacco leaves. Use value, the quality of tobacco leaves will decline only if the aging period is too long. There is a big gap between the use of traditional Chinese medicine and tobacco leaves. Tobacco leaves are mainly used for burning and smoking. Simple comparison of color depth cannot reflect the sensory evaluation and smoking quality of tobacco leaves.
The scientific paper "The relationship between the change of Maillard reaction products and the sensory quality during the natural aging process of flue-cured tobacco" (China Tobacco Science, 2015, 36(4):85-90.) only explored the changes in the content of Maillard reaction products during the aging process And its relationship with the sensory quality, did not use the reaction product to judge the quality of alcoholization

Embodiment 1

[0017] Using a method for detecting the absorbance value of the water extract of tobacco slices and judging the quality of alcoholization in the present invention, the Yunnan Pu'er Mojiang C3F grade tobacco slices that were put into storage in December 2014 were detected and quality judged. 2210 boxes, three boxes of samples were randomly selected, each box was extracted by five-point sampling method, 0.5kg sample was selected from a single box, 1.0g sample was weighed after low-temperature crushing, and the absorbance value of the water extract was measured for the sheet tobacco sample according to the detection steps, and The tobacco samples were rolled and smoked. Afterwards, 3 boxes of samples were selected every 3 months, and the tobacco samples were taken from them, and the tobacco samples of this grade were tracked and sampled, and the absorbance value of the water extract was measured and the rolling evaluation was carried out. A total of 10 samples were taken and measu...

Embodiment 2

[0032] Using the method for detecting the absorbance value of a kind of tobacco water extract and judging the alcoholization quality in the present invention, the C2F grade tobacco of Guizhou Qianxinan, which was put into storage in 2014, was detected and quality judged. When this grade of tobacco was put into storage in 2014, there was 1520 boxes, three boxes of samples were randomly selected, each box was extracted by five-point sampling method, 0.5kg sample was selected from a single box, 0.5g sample was weighed after low-temperature crushing, 15ml pure water was added, and filtered with a needle filter after standing for 30 minutes. The absorbance value of the filtrate was measured, and the tobacco samples were rolled and smoked. After that, the tobacco samples were taken every 3 months, followed by sampling of the grade tobacco samples, and the absorbance value of the water extract was measured and the rolling evaluation was carried out. A total of 11 samples were taken an...

Embodiment 3

[0042] Using a method for detecting the absorbance value of the water extract of tobacco slices and judging the quality of alcoholization in the present invention, the B2F grade tobacco slices of Huidong, Liangshan, Sichuan, which were put into storage in December 2015, were detected and quality judged. There are 1322 boxes, three boxes of samples are randomly selected, and each box is extracted by five-point sampling method. A 0.5kg sample is selected from a single box, and 1.0g sample is weighed after low-temperature crushing. Tobacco samples were rolled and smoked. Afterwards, the tobacco samples were taken every 3 months, and the samples of this grade of tobacco were tracked and sampled, and the absorbance value of the water extract was measured and the rolling evaluation was carried out. A total of 11 samples were taken and measured. Sichuan Liangshan Huidong B2F grade tobacco See Table 9 for the absorbance value of the water extract and the simulated score of the tobacco...

Abstract

The invention discloses a tobacco strip aqueous extract absorbance determining and alcoholization process determining method. The method comprises the concrete steps that (1) a tobacco strip is sampled in a five-point sampling method, and crushing is carried out at low temperature; (2) certain weight of the sample is weighed and placed in a 50ml Erlenmeyer flask, certain volume of pure water is added, extraction is carried out for 30 min, and filtering is carried out; (3) colorimetric determination is carried out in the wavelength of 355nm by taking the pure water as a blank sample; and (4) the alcoholization process of the aqueous extract is substituted into a formula, Y=-7.7913X2+45.024X+4.5655, to calculate a tobacco strip sensing quality simulated value. The method is simple and rapidin operation and high in stability, the optimal tobacco strip alcoholization period can be determined accurately, and the color darkness of the tobacco strip can be represented quantitatively. The tobacco strip alcoholization period can be mastered rapidly needless of complex operation or smoking for evaluation, and the working efficiency is improved. The method relates to fewer instruments, and the detection cost is lower.

Description

technical field [0001] The invention relates to the technical field of alcoholization of tobacco leaves, in particular to a method for detecting the absorbance value of tobacco water extract and judging the alcoholization quality. Background technique [0002] Tobacco leaf is the main raw material of the cigarette industry, and its quality determines the quality of cigarette products. Tobacco leaf raw materials harvested in that year have disadvantages such as heavy green miscellaneous gas and insufficient mellow taste, and are not suitable for direct use in cigarette production. They must be alcoholized to eliminate green miscellaneous gas and reduce its irritation. The alcoholization quality of tobacco leaves directly affects the quality and quality stability of cigarette products, and is crucial to the healthy development of cigarette enterprises. For a long time, the alcoholization quality of tobacco leaves has been mainly determined by sensory evaluation. Although the ...
