Acai berry powder results are based on dry weight (DW) tested at concentrations of 10 mg/mL (DPPH), 5 mg/mL (ABTS⁺, reducing power).
Cheongpomuk results are based on fresh weight (FW) tested at concentrations of 250 mg/mL (DPPH, ABTS⁺) and 100 mg/mL (reducing power).
AB0, Mung bean starch 40 g and acai berry powder 0 g; AB1, Mung bean starch 39 g and acai berry powder 1 g; AB2, Mung bean starch 38 g and acai berry powder 2 g; AB3, Mung bean starch 37 g and acai berry powder 3 g; AB4, Mung bean starch 36 g and acai berry powder 4 g.
All values are mean±SD (n=3).
Different superscripts (^a-e) in the same row indicate significant differences at p<0.05 by Duncan’s multiple range test.
