Antioxidant and physicochemical properties of acid degraded glucomannan

Glucomannan properties require to be adjusted to fulfill broader aplications. To adjust the properties, some modifications are conducted including hydrolysis using acid. This study aimed to evaluate the effect of glucomannan hydrolysis using citric acid on its antioxidant and physicochemical properties. The hydrolysis was conducted at various glucomannan concentrations (0.5, 1.0, 1.5, and 2%, w/v) and hydrolysis period (24, 48, 96, and 144 h)....
