Sažetak
Many reports have been published on the antioxidant activity of bioactive plant extracts. These reports have been initiated by an increasing consumer demands for safe and natural food products/additives. Beside consumers’ interest in food safe products, interest in plant extracts as a sources of important bioactive compounds that could be used in many diseases prevention is exponentially growing. As a source of bioactive compounds, primarily antioxidants, Winter savory or Satureja Montana L, of Serbian origin, has been investigated. The genus Satureja montana L. belongs to the Lamiaceae family, and comprises around 30 species. In this study two S. montana dry extracts were prepared and analyzed. First extract was prepared by spray drying process, with input temperature around 120ºC and output temperature around 75ºC. Second extract was prepared by the process of freeze-drying: liquid S. montana extract was frozen to the temperature of -20 ºC ; temperature in condenser during sublimation process was around -50 ºC, while pressure in the chamber was 0.001 mbar ; during the desorption process maximal temperature in the chamber was 30ºC ; total drying time was 36 hours. In prepared extracts content of antioxidant compounds (total phenols and total flavonoids) has been determine. To define the antioxidant activity of investigated extracts DPPH test was performed. This way analyzed extracts were combined, in amount of 2.5%, in mixture with strach, lactose and aerosil, while combination of water soluble starch and corn starch was added as a components binder. Obtained mixture was used for preparation of tablets with average weight around 250 mg.
