Recently, Beijing University of Traditional Chinese Medicine successfully completed the introduction and debugging of three sets of Japanese INSENT electronic tongue systems and one set of German AIRSENSE electronic nose system to improve the analysis and testing system of the research platform, promote the modernization and internationalization of traditional Chinese medicine research. At present, all equipment has been officially put into use, indicating that the school has made new progress in the objective and intelligent analysis of sensory quality of traditional Chinese medicine and related products.

The devices introduced this time are all instruments with good performance in the current field of sensory intelligence analysis. JapanINSENTThe electronic tongue system, with its intelligent taste analysis system using artificial lipid membrane sensing technology similar to the perception mechanism of human tongue surface taste cells, can objectively and digitally analyze basic taste indicators such as bitterness, astringency, sourness, saltiness, umami, and sweetness of food or drug samples. It can also be used for evaluating bitterness, astringency, and umami aftertaste (richness), which helps reduce subjective differences that may exist in artificial sensory evaluation. GermanyAIRSENSEThe electronic nose system imitates the human olfactory perception mechanism and can quickly identify and analyze complex odor substances. It is suitable for the overall odor fingerprint information collection and processing of traditional Chinese medicine and its preparations, food, and health products, with good sensitivity and repeatability.

Engineers provided systematic operational guidance to relevant researchers and students, ensuring that users can master the basic methods of equipment operation, daily maintenance, and data analysis.Sensory attributes are an important aspect of evaluating the quality of traditional Chinese medicine, which in the past relied heavily on empirical judgment. The application of these electronic tongue and electronic nose devices will provide support for the objective and standardized analysis of traditional Chinese medicine odor and taste indicators. They can play a role in the following aspects:

Quality evaluation and identification of traditional Chinese medicine:Analyze the differences in taste and odor characteristics of medicinal herbs from different origins, batches, and grades.

Research on Processing Techniques:Track the changes in sensory properties of medicinal herbs during the processing to provide reference for adjusting process parameters.

Improvement in taste of the preparation:Scientifically evaluate the taste and odor of traditional Chinese medicine preparations such as oral liquids, granules, and ointments to assist in product optimization.

traditional Chinese medicine-Cross disciplinary research on food:Analysis of flavor characteristics and development of related products for medicinal and edible products.

Standard research and establishment:To accumulate data for the study of sensory evaluation standards for traditional Chinese medicine based on modern technology.

The introduction of multiple sets of sensory analysis equipment by Beijing University of Traditional Chinese Medicine is an important measure for the university to promote interdisciplinary research and support traditional Chinese medicine. This measure further enhances the research conditions of the school in related fields, and provides new technical support for in-depth exploration of the relationship between the material basis and sensory attributes of traditional Chinese medicine, promoting the modern expression of traditional Chinese medicine theory, and promoting the sustainable development of the traditional Chinese medicine industry. It reflects the school's goal of relying on modern science and technology to explain the principles of traditional Chinese medicine and continuously promoting the modernization and internationalization of traditional Chinese medicine.
