Biological evaluation of protein quality
1978
Jansen, G.R.
Historical aspects of biological evaluation of protein quality are reported. A new method for such evaluation is proposed. Protein efficiency ratio (PER) is compared to Net Protein Ratio (NPR). NPR is further compared to Relative Protein Value (RPV). The implications of these comparisons for regulation of protein quality are discussed. It is proposed that PER be dropped as the regulatory method. A food serving should be expressed in terms of utilizable protein obtained by multiplying the weight of protein by the relative NPR.
