Exploiting the nano-sized features of microfibrillated cellulose (MFC) for the development of controlled-release packaging

- Microfibrillated cellulose (MFC) films loaded with lysozyme were prepared.
- MFC's nano-sized dimensions enabled slowing the release of lysozyme over time.
- The release of lysozyme was higher for simulant A than simulant C.
- The release did not change significantly at 6 °C and 23 °C.
- MFC can be used as a 'release suppressor' agent in controlled release systems.
