About Taste Sensing System / E-Tongue (Electronic Tongue)

E-Tongue TS-5000Z

  • Taste of food and beverage are composed of thousands of substances
  • Taste Sensor System can approximate and translate molecule information into visual taste information
  • Visual taste information become easily understandable and communicable when simplified and quantified
  • Quantified taste allows for Mathematical Optimization
  • Universal and visual taste information can be used effectively to interact with customers, colleagues and between global offices

TS-5000Z & SA402B are a taste evaluating device that uses sensors mimicking the human tongue in which each taste sensor is created with specific and innovative technology. This taste analysis system has taken in global selectivity for taste quality, so the output created by the sensor can be converted to information that helps distinguish differences in both taste quality and intensity between samples. In the food industry, generally, sensory evaluation has been performed by taste testing panelists who actually taste the food, but the obtained data from the sensory evaluation has been problematic in terms of repeatability and objectivity, due to differences among individuals and the panelist’s physical condition at the time of testing. Therefore, much training is required for the panelists to conduct a sensory evaluation. On the other hand, evaluation has also been done through chemical analysis which is widely applied to measure the qualitative and quantitative taste substances in food or beverages. The data is reliable and precise, but because there are thousands of taste substances contained in food or beverages that intricately react to each other, it is always troublesome to interpret the obtained data into simple and meaningful “taste” information.

For example, if we were to measure a cup of straight black coffee versus the same coffee with added sugar by way of the chemical analysis method, the quantity for bitterness-substance would be the same in both straight black coffee and sugar added coffee. However, the taste would be completely different since the added sugar would suppress the bitterness. Accordingly, it is very difficult in predicting the final taste of any food or beverage just by knowing the quantity of chemical substance included in the sample. Hence, there have been strong demands for the development of a taste sensing system that can measure taste simply and objectively to which the results can be easily interpreted. Our TS-5000Z & SA402B can show the taste intensity or difference in taste between food or beverage samples in an objective manner, similar to the human tongue. Therefore, the taste sensing system is a powerful tool to determine the target taste, assist in quality control, and will support the technicians in R&D. The data of the difference in taste, derived from the taste sensing system, can also be used for advertisement or sales promotion purposes that would send buyers clear taste information of new products. In the pharmaceutical industry, this technology can be used for the evaluation of API bitterness strength and to see how much bitterness is suppressed by a masking material (suppression effect). For better adherence, improvement in the taste of drugs is highly required, especially in the pediatric and geriatric market. Many of the global pharmaceutical companies and generic manufacturers have been introduced the taste sensing system for better adherence in pediatric and geriatric drug formulation. This system is sometimes referred to as the “e-tongue” or “electronic tongue”. Generally the “e-tongue” or “electronic tongue” is known as a system equipped with several nonspecific sensors, and in order for it to be meaningful, it usually requires a principal component analysis or multiple regression analysis method for the output of data. The “e-tongue” or “electronic tongue” that does not have selective sensors for each kind of taste commonly needs sensory analysis data to support the obtained information. At times the “e-tongue” or “electronic tongue” applies the pattern-recognition-method to predict the taste of the sample. However, the method usually needs multivariate calibration for data processing and it sometimes leads to poor repeatability in taste data. So you may wonder what is the most advantageous difference in our system compared to other “e-tongue” or “electronic tongue” available. The TS-5000Z & SA402B have selective sensors for each taste and has global selectivity with threshold adjusted to a human tongue which gives a more reliable and interpretative output.
