Comparative study of biocorrective protein-peptide agent to improve quality and safety of livestock products

Water with modified isotopic composition (D/H = 40 ppm) as a solubilizing agent for biologically active substances extraction from immune organs Sus Scrofa increases protein yield in thymus to 20%, in spleen up to 38%, mesenteric lymph nodes up to 35% in comparison with distilled water (D/H = 150 ppm). It was found a significant amount of neurotransmitter amino acids, such as aspartic and glutamic acids, glycine (thymus - 10.5; 13.7; 7.6%; spleen - 12.2; 10.7; 7.8% lymph nodes - 11.0; 13.3; 11.1%, respectively) having the immunological and adaptogenic activity, in extracts of Sus scrofa immunocompetent organs (thymus, spleen, mesenteric lymph nodes). Application of water with modified isotopic composition as solubilizing agent (D / H = 40 ppm) for extraction of immunocompetent organs' biologically active compounds led to increased amino acid content, including hydrophilic amino acids, in thymus extracts - up to 22%, in spleen extracts - up to 15% , in lymph nodes exctracts - up to 8%, in comparison to distilled water (D / H = 150 ppm). Peptide profile analysis revealed positive effect of water (D/H = 40 ppm) on a quality protein content extracts in molecular weight range from 10 to 20 kDa and from 30 to 45 kDa and peptide composition (2 kDa), at the same time quantitative content of compounds adaptogenic and immunocorrective action increased. Reducing of deuterium content in the solubilizing agent enhances quantitative amino acid content, i.e. extraction in an aqueous- salt solution based on deuterium depleted water of animal tissues with a high content of amino acids with hydrophilic radicals proceeded more completely.
