| 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. |
