| Outline of Final Research Achievements |
The quality assurance of quantitative values for evaluating food quality and safety has become an important issue in Japan and abroad, and the development of reliable analytical methods for various food-related components is desired. This study investigated establishing a method for analyzing food-related components by 1H-qNMR, which does not require a calibrant for the analyte.
As a result, we established an analytical method that can accurately measure the content of acteosides in foods and food materials using 1H-qNMR. An analytical method using the molar absorption coefficient ratio based on 1H-qNMR was also investigated for acteoside and pedaline. It was found that this method can quantify these two components in young sesame leaf powder and processed foods with the same accuracy as the conventional method.
