Abstract From the Canadian patent

To improve the quality, especially the flavour of roast coffee, the raw-coffee beans are pretreated by enrichment with saccharides. Saccharides are added to the raw-coffee beans in an aqueous solution in a proportion of approximately 10%. The enrichment of the raw-coffee beans with saccharides results in an appreciable increase in the content of "fine" acids in the roast coffee and consequently in an improvement of quality.
