Abstract:

The article presents a method of extracting galactoglucomannans from conifers: spruce and larch. Galactoglucomannans (GGMs) were extracted from shavings of Polish varieties of spruce and larch, using thermal and enzymatic treatment in an aqueous environment. The composition of the extracted GGMs (depending on the extraction method) was characterized by varied content of individual monosaccharides, i.e. glucose, galactose and mannose, as well as the average particle mass. The quantitative and qualitative composition of the extracted GGMs is an important factor affecting the possibility of their wide employment in modifying cellulose fibre-containing materials in order to improve their barrier qualities, and as biological agents in plant health products. GC/MS and SEC chromatographic tests and 13C NMR analysis made it possible to establish the composition and structural changes of the acquired GGMs.
