Protein value of two imitation milks. Chemical and biologic assays

Two imitation powdered milk products were compared with whole milk for both quantity and quality of protein. One product had comparable quantity of protein, but inferior quality, while the other had comparable quality but inferior quantity. Therefore, neither was equivalent to whole milk when a reconstituted serving of the product was calculated in terms of the U.S. RDA. However, a single serving of either product would constitute 10 per cent of the U.S. RDA for protein. Calcium contribution in terms of U.S. RDA would also be significant, but would not equal whole milk for these particular products. Thus ingredient composition varies widely for imitation milk products. These products were not evaluated for other nutrients, such as fats and vitamins.
