The study on proper distillation conditions of garlic essential oil

Objective To study the proper distillation conditions of garlic essential oil by comparing the affecting factors on productivities and optimizing producing conditions.Methods The distillation yields of garlic essential oil were compared under four affecting factors including the broken garlic fragment diameter,activator of alliinase-Fe 2+ concentration,fermentation temperature and distillation time,at three levels respectively.Results The highest distillation yield(0.49%)of garlic essential oil was gotten with0.2mm diameter of garlic fragment,10mmol/L Fe 2+ concentration,fermentation at33℃and distillation for120minutes.Conclusion The productivity of garlic essential oil is increased two times at above producing conditions.
