For the mineral composition, the analyzed fruits presented
lower concentrations of P, K, Ca, Mg and Zn and higher levels
of Fe. Furthermore, the values found for the bioactive
compounds generally fit the ranges reported in the literature with
the following minor differences: the phenolic content of the strawberry
was higher than reported; the blackberry presented higher
levels of flavonoids and raspberry was much lower than the literature;
and the blackberry, strawberry and blueberry fruits showed
lower anthocyanin contents than those found in the literature.
The greatest difference was found in relation to ascorbic acid, as
all fruits analyzed showed levels well above those found in the
literature.
