Optimization of Ultrasonic Extraction Technology of Kumquat Peel Essential Oil and Its Antibacterial, Antioxidant Activity
摘要
Abstract
The ultrasonic extraction technology of kumquat peel essential oil was optimized by a response surface methodology, and its antibacterial, antioxidant activity was further investigated. The optimal extraction conditions were as follows: liquid-material ratio of 27:1 mL/g, ultrasonic time of 1.25 h, ultrasonic power of 300 W. Under the conditions, the yield of kumquat peel oil was 2.24%, which was consistent with the predicted value. Kumquat peel essential oil displayed effective antibacterial activity for Staphylococcus aureus, Escherichia coli, Salmonella, Aspergillus niger and Saccharomycetes, and the minimal inhibitory concentrations was 1.0%, 0.5%, 0.5%, 0.5%, 0.1%, respectively. Based on the investigation of the antioxidant activity for kumquat peel essential oil, it indicated the kumquat peel essential oil could delay the shelf life of edible oil and had a certain ability to remove hydroxyl radicals, DPPH free radicals and total antioxidant capacity.关键词
