With hot water extraction at 160°C, 10.5% of wood could be extracted, which corresponds to more than 60% of wood GGM. This article is continuation to the modeling work carried out for hot water extraction and chemical pulp bleaching. The model includes galactoglucomannan, xylan, and cellulose acid–base equilibria, in addition to peeling, stopping, and alkaline hydrolysis reactions of the same carbohydrates, Borrow LU card Computers & networks Copying, scanning & printing Study spaces & reading rooms Lockers and trolleys Order digitizations Find your way around Sweden stands up for open access – cancels agreement with Elsevier LUBcat LIBRIS Galactoglucomannan (GGM) isolated from pine wood chips by hot water extraction was enzymatically hydrolysed into galactoglucomanno-oligosaccharides (GGMOs). Enzymes are known to hydrolyse GGM selectively and depending on the utilized enzyme a different pool of GGMOs can be obtained. Spruce Galactoglucomannan-Stabilized Emulsions Enhance Bioaccessibility of Bioactive Compounds Hongbo Zhao 1, spruce by pressurized hot water extraction (PHWE) [14,15]. Some lignin-derived phenolic compounds and wood extractives remain with GGM after the … Light scattering, ultracentrifuge, and intrinsic viscosity analyses were made on a glucomannan from black spruce, a galactoglucomannan from southern pine, and on mixtures of araboglucuronoxylan, arab Galactoglucomannan (GGM) 1.
