Conversion factor from nitrogen to protein for potato tuber protein

  • W. M. J. Van Gelder
Short Communication


Coagulated protein from potato tubers was analysed for total amino acids and ammonia and the resulting data were used to assess the nitrogen-to-protein conversion factor. A mixture of protein samples from 34 varieties gave a factor of 6.24, very close to the empirical factor mostly used for potato protein of 6.25. There is therefore no reason to use other conversion factors.
