Galactoglucomannan (GGM) is the main hemicellulose class in wood of coniferous trees and could be potentially utilized as a possible health-promoting substance for food and pharmaceutical industry. Our aim was to evaluate effects of orally administered GGM-rich extract from Norway spruce in a rat model of chronic prostatitis associated with In addition, two-dimensional nuclear magnetic resonance analysis revealed that the exopolysaccharide is a galactoglucomannan with a novel and unique structure, consisting of galactose, glucose, and mannose in the ratio of 1:5:3. Abstract An in vitro and in vivo study was conducted to evaluate the fermentability of isolated galactoglucomannan oligosaccharides (GGMs) and the influence of their feeding on shedding and colonisation of Salmonella typhimurium, growth performance and intestinal morphology in broiler chicks.

GGM can be hydrolyzed into fermentable sugars, or used as a polymer in films, gels, and food additives. In this work, the usability of modified O-acetyl galactoglucomannan (GGM) for modification of NFC surface properties was studied. Four GGM-block-structured, amphiphilic derivatives were synthesized using either fatty acids or polydimethylsiloxane as hydrophobic tails. Background: Galactoglucomannan (GGM) is the most abundant hemicellulose in softwood, and consists of a backbone of mannose and glucose units, decorated with galactose and acetyl moieties. GGM can be hydrolyzed into fermentable sugars, or used as a polymer in films, gels, and food additives.

galactoglucomannan (GGM) was obtained through concentration of pulp process water. Hemicelluloses can be used to produce materials. One way to increase the processability of the hemicellulose is to perform chemical modifications on it.
