Embodiment Construction

[0026] like figure 1 As shown, the tea quality rapid detection device based on characteristic aroma of the present invention includes a sampling chamber and a reaction chamber of a gas sensing device. The sampling chamber and the reaction chamber of a gas sensing device are connected by an air pump. The sampling chamber, the air pump is a micro air pump detachably connected with the sampling chamber. A gas sensor device is installed in the reaction chamber of the gas sensor device. The gas sensor device is a gas sensor array composed of a plurality of different cross-sensitive metal oxide gas sensors connected in parallel. The signal of the gas sensor device The output end is connected to the signal input end of the signal acquisition module, and the signal output end of the signal acquisition module is connected to the computer.

[0027] In this embodiment, the gas sensing device is a gas sensor array composed of four different cross-sensitive metal oxide gas sensors connect...

Abstract

The invention discloses a tea quality rapid detection apparatus and a detection method based on characteristic fragrance, which is characterized in that the characteristic information of the tea fragrance is analyzed and treated, and the quantitative analysis and qualitative analysis are rapidly and accurately carried out on the tea quality. According to the invention, a gas-sensitive sensor array is used for analyzing the tea sample smell aggregation gas in the gas-sensitive sensing device reaction chamber, by comparing the data in a computer and a database, the quality grade information of the detected sample and the characteristic fragrance content information of the detected sample can be output according to the user requirement, the characteristic information of the tea fragrance is analyzed and treated, and the quantitative analysis and qualitative analysis are rapidly and accurately carried out on the tea quality. the detection step is greatly simplified, the pretreatment of the detected sample is not required, the artificial factor interference brought by sensory evaluation can be avoided, the determination result is more objective and accurate, and the invention provides the novel nondestructive test apparatus and the detection method for detecting the tea quality.

Description

technical field [0001] The invention relates to a tea quality detection device and detection method, in particular to a tea quality rapid detection device and detection method based on characteristic aroma. Background technique [0002] Tea aroma is composed of a wide variety of low-content volatile substances. Although the content of volatile substances only accounts for 0.02% of the dry weight of tea, they play an important role in the formation of tea aroma. The aroma of tea is an important factor determining the quality and flavor of tea. Since the 1950s, researchers at home and abroad have carried out a lot of research work on tea aroma. At present, many researchers try to study the quality of tea by extracting the overall characteristic information of tea aroma. However, due to the influence of many factors such as tea tree varieties, climatic conditions, and processing processes, even tea of ​​the same variety will have different aromas. How to correctly identify tea...
