Calcium was one of the best-retained nutrients in
the fresh and frozen stored commodities evaluated over the
course of this study. In all commodities, there were no
significant differences between the frozen samples and those
that were stored fresh (Table 3). These results were consistent
with the findings of Wills et al.15 and Maklouf et al.,16 who
found that the calcium content of frozen vegetables was highly
conserved, if not higher than in fresh-stored produce.
