Abstract:Objective] The optimum process of garlic oil extraction by supercritical CO_2 was studied. Method] First, the single factor experiments were carried out to optimize the process of the extraction of garlic oil by supercritical CO_2, on that basis, the best process conditions were obtained by the orthogonal experiments. Result] The primary and secondary factors which affect the extraction rate were showed as following: extraction pressure > extraction time> extraction temperature. The optimum process conditions of garlic oil extraction by supercritical CO_2 from the garlic were showed as following:taking 15% ethanol as entertainer, extraction temperature 40 ℃, extraction pressure 25 MPa, extraction time 2.5 h and the flow of carbon dioxide was 80 L/h. Under these conditions, the extraction yield was 0.461%. Conclusion] These primary results improved the process of garlic oil extraction, and provided the theoretic basis for the industrial extraction of garlic oil.
Keywords:Supercritical CO_2 extraction  Orthogonal experiment  Extraction  Garlic oil
