[The possible carcinogenic action of a protein concentrate from Saccharomyces yeasts grown on molasses]. / Izuchenie vozmozhnogo kantserogennogo deistviia belkovogo kontsentrata iz drozhzhei-sakharomitsetov, vyrashchennykh na melasse.

A testing was done in a chronic experiment on 300 rats and 360 mice of both sexes for carcinogenic potential of a new protein product from Saccharomyces yeast grown in melasse. The production procedures and techniques of the above product have been worked out at the Ukrainian Research Institute of Spirits and Biotechnology of Food Stuffs of Gospishcheprom (State Food Industry) of Ukraine. The studies made showed the new protein product has no carcinogenic effect.

[The possible hypolipidemic action of the dietary fiber from barley meal]. / Izuchenie vozmozhnogo gipolipidemicheskogo deistviia pishchevykh volokon iz muchki iachmenia.

A possible hypocholesteremic property was studied of food fibers from barley in a subchronic experiment on 60 white nondescript male rats under developing hypercholesterolemia of alimentary genesis. An aggravated dose of the above fibers has been shown to reduce deviations from the reference level brought about by administration of exogenous cholesterin. On completing the clinical trials, the studied product may be used in nourishment of those individuals presenting with disordered lipid metabolism.

[The food value of protein concentrates made from secondary raw oil sources--oil cakes and groats from corn germ, tomato seeds, safflower and flax]. / Pishchevaia tsennost' belkovykh kontsentratov iz vtorichnogo maslichnogo syr'ia--zhmykhov i shrotov zarodyshei kukuruzy, semian tomatov, saflora i l'na.

Protein concentrates from oil cake of tomato seeds and corn bud, and groats of safflower and flax were studied for the content of the main food substances: proteins, lipids, carbohydrates, mineral substances, as well as for the fatty acid lipid spectrum, amino acid composition of proteins and the level of available lysine. In experiments on rats given rations containing protein concentrates from oil raw materials (calorific value 5.9 and 18%) as the only source of protein, the NPUtr coefficient and Dtr were determined. The maximum anabolic effectiveness was recorded with the rations containing 9% of all proteins. NPUtr value of the concentrates from oil raw materials was lower as compared to that of casein. Dtr of the concentrates fluctuated from 73 to 93%, and it was maximal when the protein level was 18%. All the protein concentrates from oil raw materials are promising for human nutrition.
