Description
|
This certified reference material (CRM) is intended for use in the quality assurance of the analysis of minor and trace elements in the Japanese diet and in similar food matrices. The starting material for this CRM was a composite stock of menus served in 29 households in Japan. The households were asked to duplicate all meals for 3 consecutive days in November 1997-January 1998 and for another 3 days in March-June 1998. The meals were typical of Japanese households and consists primarily of traditional Japanese foodstuffs with some Western dishes. The meals were frozen in the households and transported to NIES in the frozen state. The food materials were then homogenized, freeze-dried, pulverized to pass 250-μm nylon screen, blended and bottled. These procedures were compliant with ISO GUIDE 34. Then material was sterilized by 60Co irradiation (2.5 Mrad). keywords: biological material , foodstuff , nutrients , trace elements , Heavy metals |
