AbstractIn this paper changes of polyphenols in fresh
figs after hot drying and during storage are
reported. Fig fruits were analyzed before
and after hot air drying, using a tangential
air-flow cabinet and, afterwards, dried fruits
were analyzed at 4, 8, and 12 months of
storage. Polyphenol analysis by HPLC-DAD
permitted to identify four compounds:
two anthocyanins, the flavonol rutin
and the chlorogenic acid. The obtained
results pointed out the role of dehydration
in drastically reducing the polyphenol
compounds. In particular the disappearing
of chlorogenic acid after the dehydration and
of the two anthocyanins during the first four
months of storage has been observed. The
rutin decreases by 60% after dehydration,
but at the end of storage (12 months) is still
present.
