Embodiment 1

[0051] figure 1 A schematic flow chart of a quick identification method for a wine origin and brand provided by an embodiment of the present invention, as shown in figure 1 As shown, the methods include:

[0052]S101: For red wine samples with different origins and brands, prepare an olfactory visualization sensor array, collect color change information before and after the reaction between the olfactory visualization sensor and the volatile components of the red wine, and obtain the odor characteristics of the red grape samples.

[0053] Exemplarily, the olfactory visualization sensor array is prepared in advance, and the process is as follows:

[0054] Step 1: Use the pH indicator and porphyrin compounds as coloring agents for the perception of volatile components in wine. The pH indicators include: methyl red, bromocresol green; the porphyrin compounds include: 5, 10, 15 , 20-tetra(pentafluorophenyl)-21H, 23H-porphyrin iron chloride, tetraphenylporphyrin zinc, meso-tetrap...

Abstract

The invention provides a rapid identification method for wine production places and brands. The method comprises the following steps: 1) preparing an olfactory visual sensor array for red wine sampleswith different production places and brands, and acquiring color change information before and after reaction of olfactory visual sensors and volatile components of red wine to obtain odor characteristics of the red grape samples; 2) sampling each red wine sample by using an electronic tongue to obtain taste characteristics of the red wine sample, the taste characteristics including origin characteristics and brand characteristics; 3) constructing fusion features according to the combination of the smell features and the taste features; 4) taking the brand information and the production placeinformation of each red wine sample as labels of the fusion features to obtain a training sample set, and training an extreme learning machine model by using the training sample set; and 5) identifying the production place and brand information of the unknown red wine by using the trained extreme learning machine model. By applying the embodiment of the invention, detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of detection of food and agricultural product origins, in particular to a method for quickly identifying wine origins and brands. Background technique [0002] Wine is popular all over the world for its unique flavor and important health benefits. Over the past few decades, with the improvement of living standards, my country's wine market has developed rapidly, with per capita consumption rising from 0.8L in 1995 to 1.7L in 2016, an increase of nearly 112.5%. At present, there are various wine brands and varieties in the market, with a wide range of products of various grades, and the prices are uneven. What's more, there are fake wines blended with artificial pigments and alcohol solutions, and the prices are inflated. Fake alcohol will not only cause economic losses to consumers, but also directly affect consumers' health, and even endanger their lives. Therefore, it is very important to quickly, object...
