Example of application to a food traceability system
Elements such as hydrogen, oxygen, and carbon include a very small amount of heavy elements called “stable isotopes.” The content ratios of these heavy elements, which are called “stable isotope ratios,” are closely related to information on the origin of material. Laser gas sensing technology has attracted much attention because it can be used to analyze the stable isotope ratio and estimate the origin of material, including the geographic origin of food. We will apply it to preventive technology for false food labeling and others to contribute to creating a safe and secure society.
