the absence of a significant difference between the npu values of the test proteins calculated with the 1 , 2 , 3 or 4 % egg protein group as the control and the npu values obtained by the method of miller and bender ( which uses the protein-free group as the control ) demonstrated that the relative nutritive value for different proteins could be correctly determined by the traditional npu method .
