The research on recovery, valorisation, and efficient utilisation of polymeric hemicelluloses, more exactly O-acetyl-galactoglucomannans (GGM), from spruce wood can still be considered rather innovative, the burst in research intensity having started only 5-6 years ago. This paper will give a comprehensive review of some of the most interesting results and possible application areas. In our approach we are mainly interested in an intact polysaccharide that still contain most acetyl groups, which are important for a proper water-solubility and ease of handling. Furthermore, selected chemical functionalization alone or in combination with enzymatic treatments has enabled us to introduce exiting properties to the GGM. Native or functionalised GGM has then been tested and evaluated in application areas such as, emulsion stabilisation, paper, coating, biodegradable films, microencapsulation of aromas, and so on. Understanding the physico-chemical properties and development of suitable analytical techniques have been necessary along the way and will also be discussed.
