Spinach has been found to lose 13 and 46% DW of
its original thiamin content during storage for 1 and
3 weeks respectively at 4–6 ◦C. Green peas retained
much more thiamin, losing only 23% DW after
3 weeks of storage at 4 ◦C. Riboflavin also degrades
during storage. After 3 weeks at 4 ◦C, losses of 39
and 24% DW were determined for spinach and
peas respectively.41 Storage temperature can have a
significant effect; even greater losses were found in
spinach stored at room temperature.40
