The objective of this work was to extract, identify and characterize a galactose-rich heteropolysaccharide (GH) from “”jaboticaba”” peel. The best conditions to extract the GH according to a 23 full-factorial expremental design were 90°C/30 min/pH 1.0, resulting in a 32.32% yield using lyophilized sample. The chem. structure analyzed by GC/MS and NMR spectra (HSQC/HSQC-TOCSY) showed that the main chain of GH consists of a (1→4) galactoside branched at carbon 3, containing galactose (67.21%), glucose (15.78%), arabinose (9.78%), rhamnose (2.26%) and traces of esterified and non-esterified uronic acids. Rheol studies revealed that GH suspensions behave as a Newtonian fluid, with calculated mol. mass of 1.48 x 105 Da. The abstract viscosity of 1% (w/v) aq suspension of GH decreased from 25 mPa s to 10 mPa s in NaCl and 7 mPa s in CaCl2, indicating the polyelectrolyte character of GH.
