The Chinese herbal medicine special taste analyzer is a kind of taste analysis instrument, also known as the artificial taste system. It is developed on the basis of material science and sensor technology. It uses various sensor biomimetic techniques to imitate the human taste cell working mode. Achieve the detection of taste. Due to the multi-variables of different origins, different varieties, different living environments, different harvesting periods and different processing conditions, the overall taste of Chinese herbal medicines is different, and the sensors of Chinese herbal medicine special taste analyzers have different tastes. Different responsiveness is achieved to achieve the purpose of distinguishing the identification. The Chinese herbal medicine special taste analyzer is a combination of advanced sensors, with good stability and high detection precision, which is very suitable for detecting the taste substances of Chinese herbal medicine.

Puzzle, alias: puzzle, puzzle. Gingeraceae, a perennial herb of the genus Ginger. It grows under the damp forest and is distributed in Hainan and southern Guangdong. When the fruit changes from green to red in summer and autumn, it is dried or dried at low temperature. The puzzle has a specific aroma, and it is bitter and bitter.

There are certain differences in the traits and efficacy of different habitats. Therefore, it is of practical significance to classify the puzzles of different producing areas and to delineate their prices and promote them. Taste is an important indicator to judge the quality of the puzzle. Generally, the analysis of the taste of the puzzle uses modern physical and chemical analysis techniques. Although the accuracy is good, the pre-treatment and experimental process are too cumbersome, time-consuming, and demanding from the experimenter. Therefore, it is necessary to find a test method that can be simple, fast and effective to distinguish the puzzles of different origins, and provide valuable information for the classification and promotion of puzzles.
The SmarTongue Chinese Herbal Taste Analyzer of the isenso brand represented by Shanghai Ruiyi International Trading Co., Ltd. uses the interactive sensitive sensor array and signal acquisition circuit to identify the taste of Chinese herbal medicine, and comprehensively analyzes the obtained data through the data processing method of pattern recognition. Thereby achieving the identification of the taste of Chinese herbal medicine. Figure 2 shows the PCA analysis of the puzzle samples from different producing areas. It can be seen from the figure that although the distance between Guangzhou and Anhui is relatively close, it can clearly distinguish the puzzles of two different origins, while Hainan puzzle and two other origins. The area is far away and the distinction is obvious. Explain that the traditional Chinese medicine special taste analyzer can be used to distinguish puzzles from different places.
