Glucomannan with low molecular weight (MW) has been shown to increase prebiotic properties or dietary fiber content. Reducing the molecular weight of glucomannan can be done by depolymerization using heterogeneous hygrothermal degradation method. This research aimed to depolymerize glucomannan with heterogeneous hygrothermal degradation method using autoclave and to study the effect of depolymerization time and water content on intrinsic viscosity (IV), molecular weight (MW), degree of polymerization (DP), water solubility index (WSI), water holding capacity (WHC), oil holding capacity (OHC) and water content of depolymerized glucomannan (DGM). This study used a factorial completely randomized design with two treatment factors and three repetitions. The first factor is the depolymerization time (60, 90, 120, 150 and 180 minutes) and the second factor is the water content (14.58% and 35%). The observed parameters were IV, MW, DP, WSI, WHC, OHC and water content. The results showed that during the 60 minutes of depolymerization time there was a significant decrease in IV, MW and DP, then the addition of IV, MW and DP depolymerization time tended to be unstable. The decrease and increase were thought to occur due to autoclave heating which caused depolymerization, but also continued polymerization between hydrolyzed molecules and glucomannan polymers, causing an increase in the BM value. Water content significantly affects the increase in IV, MW, DP and OHC DGM. The interaction of treatment with depolymerization time and water content that has been carried out has not resulted in low MW.
