MICROBIOLOGY OF RAW MATERIALS USED FOR CONFECTIONARY PRODUCTION

Abstract

The aim of our study was to evaluate the microbiological quality of raw materials used for preparation of confectionery products. For microbiological evaluation total count of bacteria, mesophilic aerobic bacteria, coliform bacteria, yeast and microscopic filamentous fungi in samples of raw materials used in the manufacture and creams of confectionery products were detected. In addition to these groups of microorganisms the presence of pathogenic microorganisms Salmonella spp. and Staphylococcus aureus in creams was monitored. Products are assessed according to the limit values of the number of microorganisms defined in the Codex Alimentary of the Slovak Republic. For microbiological analysis of confectionery products, sampling of components of confectionary products and cream was carried out according to current health regulations and altogether 65 samples of components and creams were collected: 10 samples of raw materials sugar, 10 samples of flour, 10 samples of butter and 10 samples of eggs, 5 samples of butter yolk from cream-filled disposable bag without rum addition, 5 samples of butter yolk from cream-filled disposable bag with rum addition, 5 samples of cream-filled multiple use paid bag, 5 samples of cream-filled newly purchased paid bag, 5 samples of VenÄek corpus and 5 samples of the French cubes corpus. From raw material the highest TBC (2.65log CFU) was in flour, but the lowest in sugar (1.35 log CFU), the highest years counts was found on flour (2.42), but lowest in butter (1.18), while wasn’t in egg. In samples of creams and corpus were increased occurrence of yeast, coliform bacteria. Salmonella spp. and Staphylococcus aureus weren’t isolated from any tested sample.
