Optimization of Supercritical Fluid Extraction and Antioxidant Activity of Carotenoids from Watermelon Bee Pollen
摘要
Abstract
Response surface methodology was used to optimize conditions for the supercritical fluid extraction with carbon dioxide ofβ-carotene from watermelon bee pollen, and crudeβ-carotene extract was tested for antioxidant activity. The optimal conditions forβ-carotene extraction were found to be extraction at 51℃and 34 MPa for 80 min. Under these conditions, the extraction yield of β-carotene was 8.79 mg/100 g. The resulting extract had stronger scavenging activity against ABTS free radials than Trolox and β-carotene standard. Moreover, its total reducing power and DPPH radical scavenging activity were higher than those ofβ-carotene standard but weaker than those of Trolox.关键词
