Organoleptic and physiochemical properties and safety indicators of phytobiotic fodder additives based on herbal extracts

ABSTRACT

The organoleptic and physicochemical properties and safety indicators of phytobiotic fodder additives based on extracts of herbs growing on the territory of the Siberian Federal District have been studied in the article. It has been established that the organoleptic characteristics of the phytobiotic fodder additives are determined by the specifics of the raw materials and their processing. The following physicochemical parameters of the finished phytobiotic fodder additives have been determined moisture content, insoluble substances content in water, content of metal-magnetic admixture (particles up to 2 mm inclusive, particles over 2 mm in size and with sharp edges), and mineral impurities. The following safety indicators of the finished phytobiotic fodder additives have also been determined the content of toxic elements (lead, cadmium, mercury, arsenic), the content of dioxins, the content of polychlorinated biphenyls, dioxin-like polychlorinated biphenyls, toxicity in bioassay test, and microbiological indicators (Salmonella, in 25 g, enterococci, in 50 g, enteropathogenic E. coli, in 1 g, anaerobes, in 50 g, pathogenic Escherichia, in 50 g, yeast and mold (total), and total bacterial contamination). The amount of biologically active substances in phytobiotic fodder additives was determined in accordance with the pharmaceutical norms and regulations.
