InFig. 5are reported the value of Brix degree in fresh and dehydrated fruits; data reported are the average of three measures; for
each de-hydration method, one-way ANOVA analysis was performed in order to verify the sensitivity differences in the mean
values; high significant differences (F(5, 22) = 208.44 – p< 0.001)
were noted between the recorded levels. Brix degree is an index
of free sugar content, and it is of course expected to increase when
water is removed. In order to verify all dried samples do not contain free water, they are put in oven until stable weight in order
to assure invariable weight. The higher values regarded to biofilms seems to indicate that the apples slides are more tasty than
those obtained with other used methods.
