You can use vacuum drying or even controlled hot-air drying. However, the powder quality will be different.

Moncef Chouaibi

The freeze drying is the best technique to preserve the final quality of chitosan.

Archana Archana

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?
