영문 초록

Jeju lava seawater’s abundant minerals are known to exert antioxidant effects that remove the free radicals responsible for aging. Therefore, lava seawater reportedly possesses high commercial value as a functional food material. This study compared and analyzed the antioxidant activities of extracts from crops produced in Jeju (carrots, blueberries, and mandarins) using distilled water and lava seawater as solvents. Lava seawater extracts exhibited higher total polyphenol and flavonoid contents of blueberries and mandarins than distilled water extracts. Furthermore, the antioxidant enzymatic and 2, 2-diphenyl-1- picrylhydrazyl radical-scavenging activities of these crops were higher in lava seawater extracts than in distilled water extracts. In particular, using Vero cells, the ROS-scavenging efficacies of blueberries and mandarins were found to be higher in lava seawater extracts. Meanwhile, the antioxidant activities of carrots were higher in lava seawater extracts, despite no difference in total polyphenol and flavonoid contents. These results suggest that lava seawater exhibits favorable potential as a solvent in the functional food industry, and lava seawater-based Jeju crop extracts are potentially useful as functional food ingredients.
