Object of research - food wine, semi-sugar industry, food microflora and intermediates. The project - a study of physicochemical and biological mechanisms of influence of nanoparticles of metals and metal oxides for the correction of the microflora contamination of food products and intermediates, development of drugs based on nanoparticles for demetalization wine and develop recommendations for their use. Research Methods - sampling and preparation nanopreparativ performed by standard methods prescribed by Malvern Instruments Ltd; concentration of metals in solution were determined using the method atomnoemisiynnoyi spectroscopy induktyvnozv'yazanoyu plasma. The quality of diffusion juice - for the typical methods for beet-sugar production, the mass concentration of sulfur dioxide-free and overall, tytrovanyh acids in wine materials was carried out by typical methods for winemaking. Hardware: WD-75 autoclave, electronic scales AXIS A500, ionomer I-160m; fotoelektrokolorymetr CPK-3 microscope "Biola" thermostat MLW-4; oven MLW; water bath BW-10-2 ultrasonic dispersant UZDN-A; atomic emission spectroscope Optima 2100 DV Perkin Elmer; microwave system SpeadWave MWS-2 and SpeadWave MWS-3 + Berghof; pH-meter Crison GLP 22 with a combined electrode Crison 5201i; spectrometer OceanOptics QE-65000; analyzer particle sizes and zeta-potential Zetasizer Nano ZS; electron microscope Leo912 AB Omega; diffractometer Rigaku D / MAX 2500; microscope MBI 15U42; polarimeter SU-5, RP-2 refractometer, conductivity OK102 / 1 Radelkis; MMZM magnetic stirrer. Established antimicrobial effect of nanoparticles of metals (PNM) in low concentrations on the microflora of food and intermediates. Established long-term antimicrobial action PNM Ag on the microflora in unpasteurized beer reduced by 16% of bacterial and yeast microflora of 41% over 504 h of exposure. It is shown that drugs with nanoparticles of silver have increased mikrobiotsydnym effect in relation to the microflora of grapes and wine. Researched method of cleaning vegetable oil nanoparticles of aluminum oxide from phospholipids set rational concentration praparatu. Retrieved sorbent based on phosphorylated cellulose nanoparticles with sulfur to demetalization wine that removes 85.5% and 56.6% iron from dry white and solid white wine, respectively. For additional purification of diffusion juice in the previous stages and the main liming has been used drug nanoparticles of aluminum hydroxide which promotes cleanliness and local effect of treatment by 3.1% and 21.4% respectively. Develop appropriate guidelines. The results of the research were tested on NIViV "Magarach" and JSC "Kagarlitsky sugar factory."
