Technologically advanced taste sensors equipped with the TS-5000Z taste sensing system exhibit the specialized feature of global selectivity, providing meaningful results with high correlation to sensory scores. This system also enables the comprehensive and objective taste evaluation of foods, beverages and pharmaceuticals with high accuracy and reliability, and can be used in a wide range of fields, including R&D, marketing, quality control and quality assurance.

The TS-5000Z was developed in 2006 under the financial support program, Risk-taking Funds for Technology Development, of Japan Science and Technology Agency (JST).

For more details, see the online brochure for the TS-5000Z ( @PDF: 3.79MB).

œ@Evaluates not only the five basic tastes, but also "richness" and "sharpness", which cannot be evaluated by conventional analytical instruments.
œ@Provides a maximum of 11 kinds of taste information based on the types of taste sensors used, without having to perform complicated multivariate analysis.
œ@Outputs the same taste quality and intensity for any sample as those perceived by humans.
œ@Can be used as part of a network system and connected to other instruments, enabling simultaneous analysis by several users.

* At least a PC terminal for analysis is required.
* Depending on the network settings of a company or organization, accessing a management server from PC terminals may be impossible. Please ask our distributors beforehand if you would like to change the network settings.
