dc.description.abstractIn this study the antibacterial activity of microencapsulated rosemary hydro-alcoholic extracts against Escherichia coli K12 was observed. The tested microcapsules were previously produced in five batches varying the type of the inert core and shell material as well as the content of fresh or concentrated rosemary extract. Batch 1 and batch 3 contained equal amount of non-concentrated rosemary extract where batch 2 and batch 4 consisted of the same amount of concentrated rosemary extract. Microcapsules from the last batch 5 were impregnated with three times higher quantity of the non-concentrated rosemary extract than the previous four batches. All five types of microcapsules were tested by the agar diffusion method and showed inhibitory effect against the bacterial strain. The highest antibacterial activity was obtained for batch 5 followed by the samples with concentrated extract (batch 2 and batch 4) and the least inhibitory effect was observed by the microcapsules with non-concentrated extract (batch 1 and batch 3).
