Covalent immobilization of laccase in green coconut fiber and use in clarification of apple juice

- A process for apple juice clarification is proposed using an immobilized laccase.
- A low-cost support “coconut fiber” was used with success in the laccase immobilization.
- The derivative showed better stability in relation to the free enzyme with possibility of reuse.
- This immobilized enzyme can be used to remove phenol compounds from apple juice.
- The enzyme can be removed from the final product because it is bound in a solid matrix.
