Discriminant Analysis ofUndaria pinnatifidaProduction Areas Using Trace Elemental Analysis

[摘要] Increasingly, attention is being paid to declaring the origin of agricultural and marineproducts after the advent of the bovine spongiform encephalopathy (BSE; commonly known asmad-cow disease). The display of the production centers onU. pinnatifidahas been required in Japan since 2006. As an example of testing in another marine product, near-infrared spectra(NIR) and trace elemental analysis ofU. pinnatifidaare proven effective methods fordiscriminating production centers by us and Food and Agricultural Materials Inspection Center(FAMIC). In the present study, we found that X-ray fluorescence analysis of Br was alsoeffective for the discrimination of production centers. The results of our study suggest that acombination of NIR and X-ray fluorescence analysis is a convenient and efficientmethod for determination due simple sampling procedures and increased effectiveness.
