[Chemical composition of a protein concentrate from Saccharomyces and its effect on immunologic response].

The content of the main nutrients, as well as amino-acid, fatty-acid and mineral composition of a protein concentrate prepared from yeast-Saccharomyces grown in molasses were studied. It was found that the product contained a significant amount of protein, all essential amino acids, insignificant quantity of lipids in which saturated fatty acids prevailed. The concentrate ash was rich in calcium, phosphorus, magnesium, silicon, iron and other elements. The protein product included into experimental rations during a month produced no significant effect on the B-system immunity and did not induce sensitization.
