title: Opuntia dillenii (Ker-Gawl) Haw cladode mucilage: Physico-chemical, rheological and functional behavior.
abstract: The yield of mucilage extracted from cladodes of Opuntia dillenii (Ker-Gawl) Haw in aqueous medium was 6.2%. The neutral sugar comprised of arabinose (38.80%), galactose (33.00%), rhamnose (15.70%), xylose (5.10%), and glucose (5.10%). The mucilage showed pseudo plastic behavior with good swelling index (20%), water holding capacity (g water/g dry sample; 4±0.10) and micrometric properties. In addition, mucilage presented intrinsic viscosity of 3.7 dL/g with average molecular weight of 1.9×103kDa. The FTIR and NMR spectra of extracted mucilage showed characteristic polysaccharide nature. Further, the mucilage exhibited anti-obesity property through lipase inhibition. These findings could highlight that isolated mucilage could be exploited as an additive in food and pharmaceutical sector.
