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.
