For this reason was chosen group of plants, which were used as spices in food processing since acient times, for analyses. In scientific browsing databases were found records about chosen plants and their antibacterial and antioxidant activities and about their testing in food models. The result is a list of plants with proven antibacterial and antioxidant effects in vitro studies investigating their potential use in food preservation.
