Interesting differences, in terms of hardness (evaluated as total penetration energy), were evidenced at t0 among the candies containing GS powders and the reference samples (J), while these differences became less appreciable, even if they were significant (P < 0.05), after processing. In general, the incorporation of GS powders into fruit candies clearly modify the micro- and macrostructure of the samples. Even if they had moisture and water activity values similar to that of the reference sample (Table 1), they required higher energy to be penetrated (about 45% more for Jt23-L and Jt26-L and 70e80% more for candies containing S and M GS fractions).
