Partially hydrolyzed pectin extracted from passion fruit peel: Molar mass and physicochemical properties

Hydrolysis of polysaccharides produces low molecular weight carbohydrates with singular physicochemical characteristics, depending on the source of polysaccharide and on the hydrolysis process. The aim of this study was to partially hydrolyze the pectin obtained from passion fruit peel and to determine its molar mass and physicochemical properties. 0.25N HCl at 60 °C for 2, 3 or 4 h was used for the hydrolysis. Molar mass, uronic acid content,...
