PM0, scone added with 0% premature mandarin powder; PM1, scone added with 0.625% premature mandarin powder; PM2, scone added with 1.25% premature mandarin powder; PM3, scone added with 2.5% premature mandarin powder; PM4, scone added with 5% premature mandarin powder.
The measured concentration for DPPH radical scavenging activity and other tests (total phenol, total flavonoid content, ABTS+ radical scavenging activity and reducing power) were 10 and 20 mg/mL. respectively.
All values are mean±SD (n=3).
Different letters (a-e) in the same row are significantly different by Duncan’s multiple range test at p<0.05.
