All-Vegetable Protein Mixtures for Human Feeding

Abstract
Biological trials with chicks and rats have shown that cottonseed flour can efficiently replace the sesame flour in Vegetable Mixture 8 made of the following percentage composition: lime-treated corn, 50; sesame flour, 35; cottonseed flour, 9; Torula yeast, 3; and kikuyu leaf meal, 3. Since good quality cottonseed flour contains more lysine than sesame flour, the replacement did not appear as effective when the level of lysine in the diets was adjusted to 1.00% by adding the free amino acid when needed. Studies of corn and cottonseed flour combinations in both chicks and rats indicated that high protein nutritive value was obtained when corn contributed 15 to 25% and cottonseed flour 85 to 75% of the protein of the diet, and that sorghum could replace all or part of the corn in such a mixture without affecting the nutritive value. The experiments presented resulted in the designation of a new formula for potential human consumption. Called INCAP Vegetable Mixture 9, it contained the following percentage composition: ground yellow corn, 28; ground sorghum grain, 28; cottonseed flour, 38; Torula yeast, 3; and dehydrated leaf meal, 3.
