Design method for preferring tea aroma electronic nose sensor array through processing technology

Abstract

The invention discloses a design method for preferring a tea aroma electronic nose sensor array through a processing technology. The design method comprises the steps that sensors sensitive to tea aroma components are selected according to the tea aroma components of the specific processing technology, then sensors insensitive to the tea aroma are removed according to the sensitive degrees of theselected sensors in a tea aroma environment, and thus a primarily selected sensor set is obtained; then, relative coefficients between the sensors and distinguishing performance values of the sensorsare calculated; and the two numeral values are integrated for judging, optimal sensor combinations are screened to constitute the array, and finally, tea aroma detection and verification are conducted. According to the design method, by comparing the relative coefficients and the distinguishing performance values between the sensors, the aroma-sensitive sensor set capable of distinguishing the teaquality and the tea type is preferred.

Description

technical field [0001] The invention belongs to the field of tea aroma detection, in particular to a design method for optimizing tea aroma electronic nose sensor arrays for processing technology. Background technique [0002] The evaluation of tea aroma plays an important role in the identification of tea quality, but artificial identification methods have been used all the time. However, artificial sensory evaluation is often affected by the psychology, physiology and experience of tea tasters, and the evaluation results are difficult to be scientific and standardized, which makes people have important doubts about the evaluation results. [0003] The electronic nose has simple structure, high sensitivity and good repeatability, and can quickly perform qualitative and quantitative measurements on samples. The core component of the electronic nose is the gas sensor array, and the rationality of the sensor array plays a decisive role in the performance of the electronic nos...
