losses in fresh and frozen products (Table 7). At
least two studies have shown that no statistically
significant losses of ascorbic acid occur during storage
of canned green beans at room temperature, and one
study showed a slight loss of 6% after 18 months of
storage of canned green beans.9,27,28 These results
are consistent with classical studies suggesting strong
retention (>85%) of ascorbic acid in canned goods
stored at ambient temperature for up to 1 year.2
