| Outline of Final Research Achievements |
In order to verify the origin of agricultural products and foods which were comprised of more than 95%, stable isotope analyses of 4 elements of carbon, hydrogen, oxygen, and nitrogen were found to be useful informations with scientific fundation. We can get the information such as the origin or the glowth history from those stable isotope ratio data which are analyzed by the mass spectrometer. However, because in the bulk (whole samples) analysis that has hydrogen isotope ratio analysis problems of the precision. Therefore we proved an available method in traceability of the origin with higher precision than n the bulk isotope ratio analysis. In particular, we paid attention to rice plant cultivated in the whole Japan. We can analyze hydrogen isotope ratio values about a fatty acid which extracted from the raw rice samples, and succeeded to obtain the higher precisin data than those the simple bulk sample analysis.
