| Abstract: | Extraction of garlic oil with a freeze-drying treatment and supercritical carbon dioxide was studied. The relationship between extraction ratio and extraction temperature, pressure, time and the flux of CO2 were given by using a uniform design. The optimum extraction conditions are as following, extraction pressure 25MPa, temperature 45℃, time 5h and flux of CO2 44kg/h. The extraction ratio is about 1.19% at these extraction conditions. |
