Method for identifying white spirit flavor type by using electronic tongue system

Abstract

The invention relates to a method for identifying a white spirit flavor type by using an electronic tongue system. The method comprises the following steps that firstly, the electronic tongue system is established, wherein the electronic tongue system comprises an array sensor and a detection system; then white spirit array difference diagrams of known flavor types are obtained by the electronic tongue system, wherein the white spirit array difference diagrams of white spirit with the same flavor type are used as a white spirit standard flavor type database; and finally a detection array difference diagram of a white spirit sample to be detected is obtained by the electronic tongue system and one array difference diagram matched with the array difference diagram of the white spirit sample to be detected is found so that the flavor type of the white spirit sample to be detected is as the same as that of a standard sample corresponding to the matched array difference diagram. According to the method for identifying the white spirit flavor type by using the electronic tongue system, the change of colors of the array sensor can be directly observed; the array difference diagrams only need to be compared in the detection process and the detection is simple, convenient and rapid; furthermore, components of selected sensing substances are common chemical substances and the cost is very low.

Description

Technical field [0001] The present invention involves a method of identifying white wine, which specifically refers to a method that uses an electronic tongue system to identify the white wine flavor. [0002] Background technique [0003] Liquor is one of the six major distilled wines in the world, with a history of more than 2,000 years.The content and proportion of the aroma ingredients in liquor constitute the different styles of various fragrant liquor.At present, according to the difference in liquor flavors, liquor can be divided into strong fragrance, sauce, fragrant, phoenix, rice fragrant, medicinal, old white dried fragrant, fragrant, special fragrance, and fragrant typewait.The traditional method of liquor testing is evaluated by the wine tasting. This method mainly depends on the keen taste of the winership, but the reliability of the method is easily affected by the physical condition and spirit of the wine artist, and there is a certain subjective prejudice.Essence...

Problems solved by technology

[0004] Most of the currently reported visual array sensors are bionic sensor chips with broad-spectrum response properties, and the qualitative and quantitative identification of specific components can be realized through the different degrees of spectral changes after the sensitive unit reacts with the sample to be tested, although its applicability wide, but the lack of specificity and specificity leads to its susceptibility to various interference factors in actual detection

In addition, since the screening of sensitive materials mainly relies on large-scale instruments such as ultraviolet spectrophotometers and fluorescence spectrophotometers, the test cost is increased and the practicability of the screened materials is also affected.

In terms of liquor detection, although different liquor samples can be distinguished, it is only an overall response to the volatile aroma components in liquor, and cannot reflect the unique main components of different flavor liquors, and cannot realize personalized and specific identification, or It needs to be used in conjunction with large instruments, and real-time and on-site analysis cannot be realized
