Abstract: Antioxidation activity of garlic essential oil in peanut oil was studied by using preoxide value(POV)with oven-storage test.The results were:The activity was very strong and was enhanced with the increasing amount of garlic essential oil.Peanut oil with garlic essential oil should be stored in lower temperature.Garlic essential oil with vitamin C or with citric acid or with tartaric acid exhibited remarkable antioxidation activity and synergistic effect in peanut oil.the antioxidation activity of garlic essential oil with synthetic antioxidants(BHA、BHT、PG)was better than single antioxidant.When 0.2% garlic essenhtial oil,or 0.04%garlic essential oil with 0.005%PG was used in the oil,the shelf life of the oil could be prolonged to 24.3 months or 14.1 months at 20℃respectively.
