The linear correlation coefficients between the antioxidant compounds
and antioxidant capacity in the juices were shown in Table 2.
The changes of antioxidant capacitywere highly correlated to total phenols
with higher coefficients using FRAP assay (r=0.901–0.976) and
DPPH* assay (r=0.883–0.968), indicating that total phenols made
greater contribution to the antioxidant capacity of either cloudy or
clear juices at 4 and 25 °C. The coefficients of anthocyanins and the antioxidant
capacity were 0.776–0.945 by FRAPmethod, and 0.722–0.979
by DPPH* method.
