Determination of galactoglucomannan

from Kiwi fruit ( Schroder et al., 2001 ), from the lichens Cladonia substellata and Cladonia ibitipocae ( Woranovicz, Pinto, Gorin, & Iacomini, 1999 ), from Populus monilifera H ( Kubacková, Karácsonyi, & Bilisics, 1992 ). 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. Lundqvist, Jon et al.

Determination of galactoglucomannan

Extraction of spruce sapwood, heartwood, and thermomechanical pulp (TMP) was also compared at 160 to 180°C. Water-soluble hemicelluloses were extracted from spruce chips by microwave heat fractionation. The chips were impregnated with water at different pH values. Screening of heat-fractionation conditions, i.e.

The increasing public awareness of health and sustainability has prompted the development of functional foods rich in health-promoting ingredients. Processing technologies and sustainable multifunctional ingredients are needed for structuring these formulations. Spruce galactoglucomannan (GGM), the main hemicelluloses in softwood cell walls, are an abundantly available, emerging sustainable The galactoglucomannan had a number average degree of polymerization of approximately 30, and on complete acid hydrolysis it yielded D-mannose, D-galactose and D-glucose in the ratio 4.5 : 1.3 : 1.0.

Sprague-Dawley rats injected subcutaneously with sodium selenite at the dosage of 3.28 mgkg (-1) b.wt. were set as the model groups. Fig. 2 Specific viscosity of aqueous galactoglucomannan (GGM) solutions as a function of coil overlap parameter c [η]; 19 concentrations c are 0.011, 0.052, 0.071, 0.153 and 0.427 g ml −1, [η] = 16 ml g −1.

Extraction of spruce sapwood, heartwood, and thermomechanical pulp (TMP) was … Abstract Water-soluble native O-acetyl galactoglucomannan (GGM) from spruce is a polysaccharide that can be produced in an industrial scale. To develop GGM applications, information is needed on its stability, particularly under acidic conditions. Therefore, acid hydrolysis of spruce GGM was investigated at various pH levels and temperatures.
