Embodiment 1

[0028] A method for identifying liquor by using a fast gas-phase electronic nose system, comprising the following steps:

[0029] (1) Take 1mL of the liquor sample to be tested (see Table 1 for the brand and number of various liquor samples) and place it in a 10mL sample bottle, seal it with a silicone gasket, and let it stand for 10-30min; repeat the test 6 times for each liquor sample;

Abstract

The invention discloses a method for identifying Chinese liquor by a rapid gas phase electronic nose system. The method comprises the following steps of putting 1mL of a Chinese liquor sample to be tested into a 10mL sample bottle, sealing the sample bottle by a silica gel gasket, and standing still for 10-30 minutes; setting analysis parameters of the rapid gas phase electronic nose system; putting the sample bottle onto a sample plate, and analyzing and testing the sample by the rapid gas phase electronic nose system; and acquiring smell fingerprint information of the Chinese liquor sample to be tested, thus establishing the method for rapidly identifying the Chinese liquor by combining a principal component analytical method. A model for identifying the Chinese liquor is established, and sensory evaluation is not taken as the Chinese liquor quality identification method, so that different Chinese liquors can be objectively, digitally and comprehensively compared, and the method has a certain positive significance.

Description

technical field [0001] The invention belongs to the field of detection and analysis, and in particular relates to a liquor identification method, in particular to a method for identifying liquor brands using a fast gas-phase electronic nose. Background technique [0002] The electronic nose is a novel instrument for rapid analysis and identification of complex odors by simulating human sense of smell. It is generally composed of three parts: gas sensor array, signal processing system and pattern recognition system. At present, the well-known electronic nose systems include Alpha MOS in France, Airsense in Germany, Bloodhound and AromaScan in Britain, etc. [0003] The electronic nose is different from GC-MS, what it obtains is not the qualitative and quantitative results of one or several components in the tested sample, but the overall information of the volatile components in the sample. Traditional sensory evaluation requires well-trained sensory evaluation personnel, a...
