Abstract:

The article concerns the research results of different hardware influence on the products microbiological parameters changes and its storage parameters. Authors obtained experimental products samples on the preparatory stage while establishing the technological raw material applicability. The next stage was particle size reduction of berries (using blender knives) and temperature processing (heating to the mixture temperature of 95–110 °C). The technology involves a combination of such stages as raw materials particle size reduction, homogenization and temperature processing under the cavitation forces influence to reach the mixture temperature of 70–75 °C while obtaining experimental samples using mechanical and acoustic homogenizer (MAH) on the stage of raw materials preparation similar to the control sample. The experimental samples evaluation included the number of microbiological parameters studies (Salmonella, Coliform Bacteria, QMA&OAMO, E.coli, yeast and mildew) according to the TR CU 021/2011. Using different methods of plant raw materials processing impacts the microbiological purity of the product. The microbiological studies result analysis using hardware and technological equipment, i.e. mechanical and acoustic homogenizer at different storage time meets the safety requirements for this group of products samples. The study regulates the temperature regimes of products storage from quickbeam berries at a temperature of 20±2 °C in a place protected from direct sunlight, in consumer containers with hermetically sealed metal lacquered covers with a capacity of not more than 0.25 dm³. It proves that the vegetable raw materials processing with the effect of mechanical and acoustic impact (MAI) reduces the production line while there is no need in sterilizing the finished product, so it is possible to preserve the native raw materials properties in the heat treatment process.
