Samples of hexane-extracted peanuts, safflower seed, sesame seed, soybean seed, and sunflower seed were analyzed for their essential amino acid contents, and the nutritive values of seed proteins were determined by growth of rats fed the hexane-extracted seeds as a sole source of protein in their diets and by assay with the microorganism Tetrahymena pyriformis W. Peanuts were deficient in methionine, isoleucine, and lysine, but supplementation with these amino acids did not improve the growth-promoting properties of peanuts. Safflower seed was deficient in methionine, lysine, and isoleucine; supplementation with these amino acids improved the nutritive value of safflower seed proteins but did not bring it to that of casein. Sesame seed was deficient in lysine and isoleucine; sesame seed supplemented with these amino acids supported very good growth in rats, as did a mixture of equal parts of sesame and soybean seeds. Sunflower seed proteins were deficient in methionine and lysine and promoted good growth when supplemented with these two amino acids. Heated soybeans were deficient only in the sulfur amino acids; heated soybeans supplemented with methionine promoted very good growth of rats.
