Embodiment Construction

[0028] like figure 1 As shown, the rapid assay method of the physical properties of the flavoring essence for tobacco of the present invention is to utilize the near-infrared spectrum of the flavoring essence sample for predicting its relative density, refractive index, volatile component total amount and four physical indexes of acid value, comprising the following sequence process step:

[0029] (1) Collect samples, collect more than 30 samples of the same brand of tobacco flavor produced in different batches;

[0030] (2) Determination of content, according to "YC / T145.1 Determination of Acid Value of Tobacco Flavor", "YC / T145.2 Determination of Relative Density of Tobacco Flavor", "YC / T145.3 Determination of Refractive Index of Tobacco Flavor" " and "YC / T145.9 General Test Method for Total Volatile Components of Tobacco Flavors" to determine the acid value, relative density, refractive index and volatile component content of collected samples;

[0031] (3) Spectrum scann...

Abstract

The invention discloses a method for quickly determining physical properties of flavoring essences for tobacco by the near infrared spectrum technology, which comprises the following technological steps in order: sample collection, namely more than 30 samples of the flavoring essences for tobacco are collected; content determination, namely the index contents of the collected samples is determined according to the method stated by the tobacco industry; spectrum scanning, namely near infrared transmitted spectrograms of the samples are collected by a transmitting and sampling module of a near infrared spectrometer; model formation, namely the near infrared spectrograms of the flavoring essences for tobacco are associated with corresponding indexes after pre-processing, the optimum spectral region range and the maximum principal divisor number are selected, and a mathematical model between the near infrared spectrums of the samples and the relative index contents is established and stored into a memory; and inspection of the flavoring essences for tobacco, namely the flavoring essences for tobacco of the same trademark undergo random sampling inspection, the near infrared transmitted spectrograms of the samples are acquired and compared with the mathematical model in the memory, and the physical indexes of the samples undergoing sampling inspection can be obtained. The method has the advantages of accurate testing result, simple and convenient operation, time and labor conservation, good repeatability of the testing result, high sensitivity and so on, and is suitable to be applied in the tobacco industry.

Description

1. Technical field [0001] The invention relates to a rapid determination method for the physical properties of the flavoring essence for tobacco, which is suitable for the application in the tobacco industry. 2. Background technology [0002] Tobacco flavor is an essential and important additive in the cigarette production process. Its main function is to improve the smoking quality of cigarettes and endow cigarettes with brand-specific aroma. Strictly grasping the quality of the imported tobacco flavor is of great significance for stabilizing cigarette products. [0003] At present, the quality stability assessment of tobacco flavors is mainly based on the provisions of the tobacco industry standard "YC / T164-2003 Tobacco Flavors and Liquids", in which relative density, refractive index, total volatile components and acid value are tolerances Quantitative indicators, if two of the four physical indicators are unqualified, the batch of products will be deemed unqualified.
