Sažetak
The present study was taken up as means to find out the changes in the content of some health benefit compounds (total phenols, vitamin C and essential oils), changes in antioxidant activity and changes in microbiology status of medicinal plants (selected herbs, seeds and fructus) during their processing (cutting, grinding, sifting etc.) and production of fine cuts in the local tea factory. In investigated samples essential oil has been detected in a case of Mellisa officinalis, Mentha piperita and Foeniculum vulgare. Decrease in content of essential oil has been detected during the production of fine cuts. Highest decrease has been detected during the production of M. officinalis fine cut, 13.0%. During the production of fine cuts lowest loss of total phenolic compounds has been measured for Uva ursi, 6.133%, while highest has been found in M. officinalis case, 48.285%. Around 30% decrease in total phenols content has been detected for M. piperita and Cassia angustifolia, 33.501% and 30.035%, respectively. Similar decrease has been noticed and in the case of Vitamin C content. Applying the criteria in European Pharmacopoeia 7.0, all samples were of satisfactory microbiological quality due to the presence of Salmonella spp. (not detected in 25 g), E. coli (<103 cfu/g), total aerobic microbial count (TAMC) and total yests/moulds count (TYMC). Processing of raw materials was not significantly increased total aerobi TAMC and TYMC.
