Application Research On The Tyndall Effect In Liquor

Vintage identification of liquor is a very important subject in liquor industry.There are many kinds of liquor identification techniques and corresponding detection equipment,but they are mainly used in the laboratory and the equipment is large.However,for consumers,it is difficult to apply it to real life due to the restrictions of use conditions and actual situations.This paper mainly studies the mechanism of Tyndall effect in liquor,qualitatively and quantitatively identifies the liquor age based on the optical properties of liquor colloid,and applies the image processing technology to the measurement of the liquor colloid solution age.In this paper,the liquor vintage was identified based on the Tyndall effect.After the study of Tyndall effect,the light scattering band was determined,and the liquor vintage was identified by the scattered light intensity of the liquor.The influence of the morphology and size of the microkernels on liquor vintage was investigated from the microcosmic perspective.The quantitative relationship between liquor age and luminescence intensity was established by fluorescence spectrum.The relationalship between the Tyndall effect and the year was studied by extracting the target material from the Tyndall light pathway,which proved the feasibility of using the Tyndall effect to identify the wine year.The main work of this thesis is divided into three parts:The relationship between Tyndall effect and liquor vintage was studied.The relationship between the white wine vintage and the white wine colloid was established from three aspects:the scattering characteristics of white wine colloid,the morphology of white wine colloid and the size distribution of colloidal granules.Through the Tyndall effect of liquor,the scattering state of liquor was analyzed from the shallow to the deep,from the macro level,and then the influence of the micro-colloidal morphology and particle size distribution on the Tyndall effect was analyzed.From the surface to the inside,from the phenomenon to the mechanism,the feasibility and accuracy of the Tyndall effect of liquor was explained.The Tyndall effect of liquor has a certain ability to distinguish the quality of liquor,if combined with a variety of data analysis methods,the difference effect is better.The relationship between fluorescence spectrum and liquor year was studied.The year of sauce-flavor liquor was studied from two aspects: excitation spectrum and emission spectrum.In the excitation spectrum,the spectral intensity is proportional to the year,the greater the intensity,the greater the year.In the emission spectrum,the optimal excitation wavelength of white spirits varies with different years.With the increase of the age of white spirits,the optimal excitation wavelength gradually shifts to blue.At the peak of the emission spectrum,the intensity of the peak has an obvious linear relationship with the year,which can quantitatively realize the correct discrimination of white spirits of different years.The digital image processing of baijiu Tyndall effect was studied.In maotai-flavor liquor,for example,collects the ding of maotai-flavor liquor total effect diagram,then Matlab software for processing,will be collected the target color images are extracted and converted to gray image,and the histogram statistics,observing the histogram of pixel distribution,the establishment of a liquor butyl antipodal relations with year total effect,The Tyndall effect can be used to identify the vintage of liquor.In this paper,the vintage identification of liquor was realized by Tyndall effect as the carrier,and the goal of visual liquor identification was preliminarily achieved,which provided a new idea for liquor identification and a theoretical basis for the quality inspection of liquor production.
