Problems solved by technology

This method has problems such as long analysis time, complicated process, cumbersome detection steps, etc. due to the large difference in the response of different chemical components on the gas chromatographic detector, the actual real ratio cannot be detected, and rapid on-site detection cannot be realized.

Embodiment Construction

[0024] The present invention will be further elaborated below.

[0025] Take a tobacco flavor composed of three grades A, B and C flavors and solvents as an example, and measure the actual grades A, B and C of samples 1 to 5 in the samples to be tested through steps 6 to 10 The ratio of flavors.

[0026] Step 6: Take tobacco essence grade A, grade B and grade C flavor samples as standard samples, each take 1 g and dilute with 50% ethanol aqueous solution without ultraviolet absorption, and the dilution ratio is 100 times;

[0027] Step 7 Take 1 gram of flavor sample 1 for tobacco to be tested, 2 samples of flavor for tobacco for testing, 3 for flavor of tobacco for testing, 4 for flavor of tobacco to be tested, and 5 samples of flavor for tobacco to be tested, and use 50% of non-ultraviolet absorption Diluted with ethanol aqueous solution, the dilution ratio is 100 times;

[0028] Step 8 measures the ultraviolet absorption spectrum of the standard sample prepared in step 6, ...

Abstract

The invention discloses a method for fast measuring essence mixture ratio in cigarettes, which comprises the steps of: adopting all brands of sample essence for tabacco as a standard sample which is diluted with a solvent without ultraviolet absorption; diluting a sample essence for tabacco to be measured with the solvent without ultraviolet absorption; measuring the ultraviolet absorption spectrum of the standard sample and the sample essence for tabacco to be measured; taking the absorbance values corresponding to all wave lengths of the obtained ultraviolet absorption spectrum as independent variable matrixes, and taking the mixture ratios of all brands of essence for tabacco as dependent variable matrixes so as to construct an operational matrix; and operating the matrix by multivariate curve resolution-alternating least square method so as to obtain the actual mixture ratios of all brands of essence for tabacco. The method overcomes the defects of long analysis time, complex process, complicated detecting steps and incapability of on-site rapid test, and provides a simple method which reflects the actual mixture ratios of essence for tabacco, uses few testing instruments and can realize on-site rapid test, thus being capable of being widely used in tobacco manufacturing.

Description

technical field [0001] The invention relates to a method for measuring mixtures, in particular to a method for detecting the ratio of flavoring essence for tobacco. Background technique [0002] Tobacco flavor is a complex multi-component chemical system, which is prepared by blending various raw materials and appropriate solvents. It is affected by many factors such as raw materials, processing technology, and processing environment. It is difficult to determine its intrinsic properties only from its physical properties. Effective monitoring of quality. The essence in cigarettes has a special impact on the smell of cigarettes, and is an important indicator for smokers to evaluate cigarettes. The current common practice is to monitor the quality by measuring physical and chemical indicators such as acid value, relative density, refractive index and miscibility according to YC / T 145-1998 industry series standard methods. In the production process of cigarette products, the ...
