Accurate determination of the distribution of substitutions in the primary molecular structure of heteropolysaccharides and their derivatives is a prerequisite for their increasing application in t

AcGGM has a large potential as a biorefinery feedstock and source of oligosaccharides for high-value industrial applications. Steam explosion is an effective method for extraction of carbohydrates from plant biomass. Increasing the reaction pH reduces the combined Victor Kisonen currently works at Bio-Co Group and he is responsible of developing sustainable solutions for horticulture.

Acetyl-galactoglucomannan has been reported to have an approximate DP between 100–150 (Timell, 1967), equivalent to a molecular weight (M w) around 16 000–24 000 Da. It has a backbone of β-(1→4)- d -Man p and β-(1→4)- d -Glc p residues with α-(1→6)- d -Gal p and acetyl side-groups.
