Optimization of the extraction of galactoglucomannans from Pinus halepensis

Abstract: The effectiveness of pressurized hot-water extraction conditions for obtaining galactoglucomannans (GGMs) from Pinus halepensis suitable for applications like coatings and films packaging was investigated. For this purpose, high molar masses with high yields are required, presenting a serious challenge for hot-water extraction processes. The extraction of GGMs was carried out in an accelerated solvent extractor (ASE) and the isolation was performed by precipitation in ethanol. Three temperatures in the range 1… Show more

“…In the study [18], the same research team examined the effect of steam explosion conditions on the extraction of hemicelluloses from spruce sawdust,the weight-average molecular weight M w of hemicelluloses obtained in a neutral medium was found to be 9-27 kDa and the PDI value was 2.3-2.6. The work [40] studied the hightemperature extraction of galactoglucomannan from pine wood. M w at optimum extraction parameters of 7 kDa at 170° and an extraction time of 20 min.…”
