Al-Rudainy, Basel - Galactoglucomannan recovery from softwood spent sulfite liquor: Challenges, process design and techno-economic evaluations Al-Rudainy, Basel - Galactoglucomannan Recovery with Hydrophilic and Hydrophobic Membranes: Process Performance and Cost Estimations 2018-04-19 · 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. 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.

Three reference systems  This thesis presents the utilization of the water-soluble species O-acetyl-galactoglucomannan (AcGGM), derived from softwood, as raw material for the synthetic  Abstract : Galactoglucomannan and galactomannan are among the most abundant plant polysaccharides in nature. The central enzymes involved in their  A class of nonionic polysaccharides-based surfactants were synthesised from O-acetyl galactoglucomannan (GGM), water-soluble hemicelluloses from spruce,  The physico-chemical properties of the industrially-recovered spruce galactoglucomannans were studied. The solubility after filtration was determined by GC. Mikkonen, K. S., Heikkila, M. I., Helen, H., Hyvonen, L., & Tenkanen, M. (2010). Spruce galactoglucomannan films show promising barrier properties.

The aim of this master thesis project is therefore to investigate the foaming ability of galactoglucomannan.

Native galactoglucomannans (GGMs), which were isolated from thermomechanical pulping waters of Norway spruce, were modified through cationization, carboxymethylation, and imination at the reducing end with a primary long-chain hydrocarbon amine. The derivatives were tested for their papermaking properties. The carbs, predominantly a group known as "GGMOs"--short for galactoglucomannan oligosaccharides--are a key ingredient in Previda, an all-natural dietary ingredient marketed to makers of pet food, aquaculture feed, and other animal-nutrition products. Dogs, pine trees, and carbs: studies lead to new pet-food ingredient Galactoglucomannan (GGM) from spruce was studied with respect to the degradation behavior in alkaline solution.

Altered Thermal and Mechanical Properties of Spruce

acetylated galactoglucomannan (AcGGM), enabling this raw material to be utilized in the synthetic design of new classes of materials. Based on the chemical modification of the hydroxyl groups with crosslinkable groups in combination with the naturally high hydrophilicity, synthetic pathways for the production of functional hydrogels are presented. The galactoglucomannan (GGM) extraction was evaluated on the basis of weight-average molecular weight (MW), yield and carbohydrate composition of the GGM. The MW was determined by size-exclusion chromatography with column calibration using off-line MALDI-MS analysis, and determination of mannan content in the fractions collected.
