| Outline of Final Research Achievements |
Improving the reliability of food labeling is vital to guaranteeing the safety of our food. In order to determine the origins of calcium carbonate (e.g., the shells of living organisms, synthetic materials, and minerals), in this study we used inductively coupled plasma mass spectrometry to measure the amounts of group 2 elements in our samples, as well as their stable isotope ratios. Our results indicated two things about calcium carbonate. First, that it is possible to distinguish between calcium carbonate which derives from the shells of living organisms and other kinds of calcium carbonate. Second, that it is possible to distinguish between samples which derive from synthetic materials and those which are from minerals.
