The approval of use of certain food-grade phosphates as food additives in a wide variety of meat products greatly stimulated research on the applications of phosphates in foods. Although phosphates have never been classified as antimicrobial agents, a number of investigators have reported that phosphates have antimicrobial activities. Phytic acid is a natural plant inositol hexaphosphate constituting 1-5% of most cereals, nuts, legumes, oil seeds, pollen, and spores. In this study, we investigated antibacterial activities of sodium phytate (SPT), sodium pyrophosphate (SPP), sodium tripolyphosphate (STPP) on Salmonella typhimurium in tryptic soy broth and in row meat media including chicken, pork and beef.

In the conditions of the Republic of Belarus annually in 25-50% of total number cattle there was stated ketosis (milk fever); as a result, from each cow in cattle breeding farms receive less milk per lactation on 10-15%, as well as there is a lowering of fat and protein (and biological value) content in milk. In course of the study there was analyzed the influence of mineral and energy supplement Felutsen K-1-2 for the preventive treatment of ketosis of highly productive cows. Research results showed that application of the analyzed additive rendered the positive influence on morphological and biochemical blood indexes. In particular, there was an increasing of hemoglobin level, content of total protein, albumins, magnesium, calcium, and phosphorous. It also rendered positive influence on lipid exchange. In course of the study it was marked, that the prophylactic efficacy of mineral and energy supplement Felutsen K-1-2 in the experimental groups was 100%, and the control one – 80%.
