Popis: Nowadays the use of plant raw materials of the Far East receives increasing relevance for food purposes. The article presents the research on safety and relative biological value of drinks on the basis of extracts of Manchurian walnut pericarp using the test for protozoa, in particular, on Tetrahymena pyriformis infusorian. The results obtained show that the drinks on the basis of the extract of Manchurian walnut pericarp and hawthorn infusion have beneficial effect on the growth and development of protozoa. It has been shown that protozoa generation and the size of their cells increase with storage and slightly differ from the control sample. Besides, tests of the presented samples possess rather high biological value. Turbidity and molding of the environment in tests are not observed with the increase of storage life. It indicates that the drinks on the basis of the extract of Manchurian walnut pericarp and hawthorn contain biologically active agents preventing the development and growth of micromycetes, sporous, semi-pathogenic and pathogenic bacteria. The quality assessment of the drink on the basis of the extract of Manchurian walnut pericarp with the addition of hawthorn infusion has been conducted in microbiological indices and the content of heavy metals in it.
