Supercritical fluid extraction of essential oil from cryo ground ajwain seed


Author(s): Sardar NR, Prasad RV, Sharma HP, Bhatt HG, Tagalpallewar GP and Fenn BN

Abstract: The experiments were conducted to optimized the processing parameters i.e. temperature, pressure, dynamic time and static time for maximum essential oil yield from Ajwain seeds (Trachyspermum ammi L.) and shelf life evaluation of essential oil at College of Food Processing Technology and Bio-energy, Anand Agricultural University Anand Gujarat. A Response Surface methodology (RSM) was used for the determination of optimum extraction temperature (35,40,45,50,55 °C), pressure (100, 150, 200, 250, 300 bar), dynamic time (30,60,90,120,150 min) and static time (30,45,60,75,90 min) were evaluated with respect to essential oil yield from Ajwain seeds using supercritical fluid extraction process. The shelf life evaluation of the extracted essential oil from Ajwain seed was also carried out at two storage temperature-18 ± 2°C and 7 ± 2° C. The maximum essential oil of 3.9% was found by using temperature, 300 bar pressure with 65 min and 30 min dynamic time and static time respectively. The degradation of the essential oil was found less stored at -18 ± 2°C as compaired to the essential oil stored at 7 ± 2°C.
