Možnosti ovlivnění mikrobiologické čistoty potravin pomocí léčivých rostlin
Havelková, Lucie
Object of this thesis was to observe the microbiological purity of the juice and possible influence on purity by using extracts from selected species of medicinal, aromatic and culinary plants (MAPs). Presence of groups of Clostridium, Bacillus, E. coli, Enterococcus, Pseudomonas, molds and yeasts, psychrotrophic microorganisms and the total bacterial count was evaluated. Extracts of these kinds of plants were added to opened juice containers: fennel (Foeniculum vulgare var. dulce, L.), chamomile (Matricaria recutica, L.), hop (Humulus lupulus L.) and caraway (Carum carvi L.). Very good results after adding the extracts were achieved in growth restriction of groups of Clostridium, Bacillus, E. coli, Enterococcus and Pseudomonas. The extracts did not affect the growth of psychrotrophic microorganisms, molds and yeasts.
