Protein-rich mixtures for human consumption based on fish flour, sunflower presscake meal, dried skim milk and wheat flour

Abstract

1. The quality of the protein in five high-protein mixtures intended for human consumption and made from materials that are available in Chile is reported. 2. The ingredients were fish flour, bread, wheat (Triticum sativum Lam.) flour, roasted whole wheat flour, a wheat flour made from a variety of durum wheat (T. durum Desf.), skim milk and sunflower presscake, mixed in different proportions. 3. The net protein utilization when fed to rats in diets at the 10% level of protein calories gave values in the range 66—76, which compare well with that (67), found for Incaparina, an all-vegetable mixture produced by the INCAP Group and used in Colombia, and are higher than the values (55 and 56) obtained for Peruvitas, which are mixtures made up basically from cottonseed and quinoa reinforced with dried skim milk. 4. The protein values of the mixtures, expressed as net dietary protein calories %, were calculated from their biologically determined net protein utilization (operative), and gave
