The water activity (aw) is an
intrinsic product characteristic that influences the
microbial ecology of a sugar-rich product. It defined
as free moisture content in the product. Both of
moisture content and aw are highly important for the
shelf life of osmo-dried cantaloupe during storage.
No difference in moisture content was found between
sample produced by FOD and SOD (P>0.05). On the
other hand, SOD-treated sample had a lower aw than
FOD-treated sample (P
