Cellulose from Citrus Pectin Biorefinery Residues: insights on Crystallinity Changes by ATR-FTIR and ¹³C ssNMR

Short Introductive summary

Cellulose is a linear biopolymer formed by glucose units linked by beta-1,4-glycosidic bonds. It is the main biopolymer on Earth. Due to the multiple well-known properties of cellulose, like biodegradability, it is widely investigated for applications in many fields. Cellulose units are maintained together by intermolecular interactions through hydrogen bonding of the hydroxyl groups forming highly ordered structures [1]. Cellulose can be obtained from different sources, and nowadays, biomass as its green resource has gained great importance, since it is a way to add value to the biomass byproducts from industrial processes like juice production. Citrus biomass (CB) is an example of cellulosic biomass with an average of 10-20% of cellulose. Although pectin is the main polysaccharide of the CB, after its extraction, cellulose becomes the main one. In this sense, the byproduct of the extraction of pectin is a sustainable source of cellulose.
