Abstract A commercially available single-cell protein (Pruteen) was analyzed for amino acids, fatty acids, and major, minor, and trace-element composition after storage at room temperature and at 4°C over a period of 5 years. The purpose was to assess its suitability as an organic-nutrient standard reference material for food analysis. The material showed longterm stability and is, therefore, recommended for interlaboratory certification studies.

Good Agreement

A method is described for obtaining the concentrations of trace elements in samples of low-Z matrix by measuring the intensities and transmittances of such samples of intermediate thickness in pellet form. This method has been applied to the determination of the minor and trace elements of Certified Reference Material IAEA/V-10 hay powder, and the results are in good agreement with quoted values.
