Is there any alternative for a freeze-drying method for drying of the chitosan polymer matrix?
You can use vacuum drying or even controlled hot-air drying. However, the powder quality will be different.
The freeze drying is the best technique to preserve the final quality of chitosan.
Moncef Chouaibi Can I freeze dry chitosan at -20 C ? We don't have the regular freeze drying machine.
Jasim Ahmed How much temperature will be sufficient to dry the chitosan beads?
