The present study showed a simple way of isolation of
hemicelluloses with different degree of branching, molar mass, functional
groups, varying lignin content from sugarcane bagasse and demonstrated a
significant water barrier property on cardboard. The hemicellulosic
polysaccharides from sugarcane bagasse was extracted sequentially with steam
treatment followed by alkali and were characterized by chemical methods,
SEC-MALLS, FT-IR and 13C NMR. While alkaline peroxide extraction produced
mostly linear arabinoxylans with varied amounts of lignin, the hemicellulose
from steam pre-treatment was discovered to contain gluco-arabinoxylans. On
cardboard, these high-lignin arabinoxylans were tested for water barrier
qualities in preparation for usage as food packaging materials. Due to lignin
content, these hemicelluloses were found to increase the water barrier
properties of the cardboard. Furthermore, the novel coating material shows
promising properties for the development of sustainable barrier material in
fibre-based packaging material to replace oil-based barriers.
