[Nutritive value of a new protein product--dry protein mixture]

A dry protein mixture (DPM) consists of dry slaughtered animal blood clarified by means of the peroxide-catalase system and dry skim milk at a ratio of 1:1. A study was made of organoleptic properties of the DPM, the composition of nutrients and biological efficacy in experiments on animals. The DPM is light yellow powder without specific taste and odor of blood, contains 58.4% of protein, 1.36% of fat, 26.71% of carbohydrates (lactose), and 8.19% of mineral substances. DPM proteins contain all the essential amino acids. As regards their biological efficacy they are not inferior to that of casein. The DPM is rich in calcium (606 mg/100 ml), phosphorus (645 mg/100 ml) and particularly in iron (106 mg/100 ml). Digestibility of iron examined on rats appeared to be high (31.2%). The new product is recommended for rational and dietetic nutrition.
