As hemicellulose is the easiest fraction to recover from the BSG matrix, its use as starting material for polymer synthesis is an appealing strategy. However, polymeric or oligomeric hemicellulose exhibit weak properties requiring plasticisation, blending with another material or chemical modification. films with antioxidant, antibacterial and antifungal properties. Similarly, a combination of cellulose and polymeric AXs (ArabinoXylans) from BSG can also be used for food packaging production with good mechanical and thermal stability. Qazanfarzadeh et al. recently reviewed the fractionation of BSG's matrix comparing various biorefinery strategies with the use of each fraction for films and coatings applications in the food packaging sector, showing the potential of this promising renewable resource. The mixture of lignin, hemicellulose and cellulose proved to be difficult to use as such for film forming application, requiring separation, ideally with high purity to improve the properties of the respective biopolymers. Thanks to its high intrinsic mechanical and water-resistant properties, cellulose can be used by itself for film and coating applications or mixed with other compounds like naringin to improve UV-blocking and barrier properties for example. Using the cellulosic fraction after its isolation in alkaline conditions followed by bleaching, Martins dos Santos et al. reported its conversion in a microwave reactor to the functionalised polymer CMC (Carboxy Methyl Cellulose). The optimised synthesis of the polymer offered a greener pathway compared to the industrial method with a broad spectrum of applications for CMC: paper, textile, pharmaceutical, paint and food sector.
