Abstract
Protein quality of eight peanut (Arachis hypogaea L) cultivars was evaluated using chemical, biological and microbiological techniques. The chemical score for S‐amino acids and lysine in peanut cultivars ranged from 37 to 50 and 47 to 55%, respectively. Protein efficiency ratio and relative nutritive value of peanut proteins varied significantly from 1.45 to 1.76 and 45.6 to 54.2%, respectively. Relative nutritive value was significantly associated with chemical score (r = 0.98**) and protein efficiency ratio (r = 0.88**), and therefore could be used as a quick method to measure protein quality of peanut cultivars.
