Savchuk G. Veterinary and sanitary milk examination by different ways and regimes of pasteurization

Object of research: milk pasteurization by the using of different types of pasteurizers and regimes of pasteurization. Purpose of research: studying the efficiency of different methods and regimes of pasteurization and their influence on veterinary-sanitary and gualitative indices of milk. Methods of research: bacteriological, biochemical, physics and chemical investigation, methods of biological experiment, statistical. Scientific novelty: scientifically grounded parameters of control process of milk pasteurization on the base of critical point of control for securing the indices of its safety by the microbiological, physics and chemecal, technologiсal indices by the conditions of the using of three types of pasteurizers: plate, cavitative and infrazed heating. Thanks to the experiment it has been chosen the effective tempera-ture regimes for termical destruction of unwished microor-ganisms in row milk depending on it microbial number during the pasteurization on highmentioned pasteurizers. It was also defined the influence of methods and regimes of pasteurization on the content of remainded microflora in pasteurized milk depending on sanitary-hygienic state of row milk. Defined critical limits for temperature regimes at the point of pasteurization control which has 79,5???C for infrared pasteurisers, and 79 ?C without exposure for cavitative mounting. The efficiency of milk pasteurization at the temperature of 79 ?C on cavitative mounting consists of 99,9 per cent, on plate pasteurizer-99,7 per cent were de-fined too. Scientifically grounded scheme of multiplication of microbiological pasteurized milk during guaranted terms of serving for the determination of pasteurization efficiency. Degree of introduction: during the inspected veterinary control and inspection at milk processing enterprises, it was proposed to use the analysis of dangerous facts at such critical place of production as pasteurization. Wich the purpose to get milk and milk products of high guality and safety in veterinary and sanitary correlation, we should use the cavitative installation of pasteurization and pasteurisers of infrared heating. Materials of theris were used in SSUA 3662-92 (Cows unskimmed milk. Demands at purchasing). Sphere (field of using): enterprises of milkprocessing in-dustry, state laboratory of veterinary and sanitary investigation.
