[Dynamics of the uptake of free amino acids in the blood serum of the portal vein during the digestion of isolated krill protein].

The rate of absorption of amino acids obtained from isolated krill protein administered to rat stomach was studied. Absorption of casein amino acids was determined for reference purposes. Rats subjected to 48-hour fasting were administered krill isolate and casein in the form of homogenates at a rate 540 mg protein per 100 g bw in 6 ml of distilled water.

[Safety of a new food product--a dry protein mixture].

A study was made of the safety of a product consisting of dry clarified blood obtained by means of the peroxide-catalase system, and dry defattened milk in a ratio of 1:1. White rats received the diets containing casein as a source of protein (control) and a dry protein mixture (experimental). In acute experiments, the animals received 36% of protein as regards the caloricity, the experiment lasted 30 days.

[Principles and methods of hygienic evaluation of new protein products].

Modern approaches to the study of the quality of new protein products are reviewed. It is suggested that the food value of the products (organoleptic properties, the composition of nutrients, biological value) and their safety for the animal body should be examined. A possible chronic toxic and sensitizing action of new protein products, their effects on reproductive function, and mutagenic and cancerogenic action were studied in animal experiments.

[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.
