The subsequent mashing and pressing steps resulted in significant
increases in TPC (36% increase), TFC (14% increase), TMA
(188% increase) (Table 1), as well as TAC (18% increase with
CUPRAC, 16% increase with DPPH, and 76% increase with ABTS
assay) (Table 2) present in initial (pressed) juice as compared to
the original fruit concentrations, as determined on a dry weight
basis (p < 0.05). On the other hand, the percent PC was 16% lower
in the initial (pressed) juice than in fresh mulberry fruit, which
was consistent with an increase in TMA levels (Table 1). Similar
increases in TPC, TFC, TMA, and TAC were also obtained with the
steps of mash heating (80 C, 90 s) and pressing included during
sour cherry juice processing (
