The results of Fourier trans-form infrared (FTIR) spectra of KG and KOG indicated that KG was successfully degraded.
In addition,their antioxidant activities were evaluated by determination of hydroxyl radical (•OH) and 1,1-diphenyl-2-picrylhrazyl radical (•DPPH) scavenging activity, and determination of reducing power.
The resultsshowed that KOG exhibited significant antioxidant activities. Taken together, this study suggested thatKOG could potentially be used as a natural antioxidant.
