Influence of Drying Temperatures on Essential Oil Content in Savory Satureja montana L. (Lamiaceae)
Aromatic and medicinal plants like savory which produce essential oil and other active components are used in medicine and food processing industry as flavor, spice etc. On the market savory is present as dried herb, leaf drug, essential oil, extracts etc. Essential oil glands and trichomes of savory are located on the surface of stems, leaves and calyces, accordingly drying and processing of savory have huge influence on essential oil content in savory drugs. A research on wild growing savory from the Istrian peninsula was carried out at Polytechnic of Rijeka, Agricultural Department in Poreč. Drying kinetics and influence of drying temperatures (35, 40, 45, 50, 55 and 60°C) were investigated on selected parameters of savory collected in winter 2012, in the area of Rovinjsko selo in Istria, Croatia. The percentage of dried leaves in fresh herb, essential oil content and proportion of dried leaves in fresh and dried herb were defined. The average of initial water content was 80, 06 %, essential oil content 0, 776 ml100g-1 and the proportion of dried leaves was 50, 56 % in the dried herb. Higher drying temperatures expectedly reduced the essential oil content. The reduction of essential oil content at 45°C was 14, 8 %, while further temperature increase to 50°C resulted with a 59, 4 % lower content of essential oil in the drug.
