The freeze-dried ATBC exhibited a 2.32% rehydration ratio.
Although ATBC/G composites showed a higher rehydration ratio,
the rehydration ratio in the low ATBC ratio composites were lower
than those in high ATBC ratio composites. The crosslinking treatment
remarkably increased the composite rehydration ratio,
particularly for EDC crosslinking at low ATBC ratio composites
(Fig. 4b). The lower rehydration ratio of higher gelatin content in
composites owes to the bigger solid weight in the denominator
during calculation.
