[Mineral composition of the protein concentrates made from nontraditional raw plant materials].

Protein concentrates obtained from unconventional plant raw material, namely from the oil cake of tomato seeds, corn germs, flax and safflower hold promise as sources of biologically important components including mineral substances. The protein concentrates are marked by a high content of calcium, magnesium, phosphorus, copper, manganese and zinc. They are also rich in iron that occurs in the form of a protein complex of bivalent iron.

[Hygienic evaluation of the meat of pigs given a feed concentrate prepared from overflow active sludge].

The authors studied the chemical composition of the meat of pigs given the diet containing a feed concentrate obtained from excess active sludge and the effects on the laboratory animals of such meat fed for a year. As compared to the accepted standards, the meat of pigs given the feed concentrate showed high cadmium content in the kidneys and high lead content in the liver and muscles. Starting from the 6th month of being kept on the meat of experimental pigs, the rats demonstrated an appreciable increase in the count of peripheral blood reticulocytes which remained almost unchanged to the end of experiments.
