Analiza mikrobiologiczna produktów mlecznych i potencjalne źródła ich skażenia

Control and evaluation of a trade value of dairy products have an essential significance because of their great supply and demand. Consumers expect that the milk and extremely rich range of milk products would be safe i.e. free of physical, chemical and biological risks. Taking into account that this food offers perfect conditions for development of microorganisms, a milk contamination can cause undesirable changes of its products, so this paper is focused on definition of potential sources of contamination in a process of production of kefir and soured 12% cream. From the investigations carried out throughout four seasons of a year a conclusion was drawn that in a course of the production of pasteurized milk, kefir and cream the critical points of control are the stages of collection and reception of a raw material, its pasteurization and chilling and a packaging. These are the points of a production process which essentially influence the safety of quality of a final product.
