Effective processes are provided for the production of xylitol and ethanol and other products from solutions derived from lignocellulose-containing material in biomass. The solutions can be hydrolyzed or partially hydrolyzed before being fermented with microbes. The fermented solution can be distilled and can be subsequently separated, such as, by chromatographic separation, membrane separation, etc. The recovered xylitol solution can be crystallized to provide pure xylitol crystals.

A process for manufacturing xylose by extracting hemicellulose from a cellulosic material, such as by a cold caustic extraction method, concentrating the extract, such as by nanofiltration, into a hemicaustic stream containing hemicellulose with greater than about 85 wt % xylan content, and subsequently hydrolysing the xylan from the hemicaustic stream to xylose. The high concentration of xylan within the concentrated hemicaustic stream enables hydrolyzation of the xylan to food-grade xylose and, optionally, hydrogenation of the xylose to xylitol without the need of a chromatographic separation step as previously required.

A method for producing a chewing gum, as well as the chewing gum so produced, incorporates a physiological cooling agent, such as acyclic carboxamide, or combinations of physiological cooling agents. In another embodiment a combination of physiological cooling agents is made in a modified release structure. The modified release/cooling agents combination is preferably obtained by physically modifying the properties of the combination of cooling agents by coating and drying. When incorporated into gum, these particles are adapted to enhance the shelf stability of the flavor and/or produce a modified release when the gum is chewed. In another embodiment, the physiological cooling agent is present with menthol and menthone. In another embodiment, coated chewing gum has a coating that comprises a physiological cooling agent. The preferred inventive chewing gum provides a high flavor impact in which the harsh notes normally associated with such a high flavor impact have been reduced or eliminated. In addition, the preferred inventive gum provides a clean, high-quality, cooling chewing gum coating with xylitol or other polyols where xylitol has been reduced in concentration or eliminated.

A strain of xylose-utilizing Zymomonas was engineered with a genetic modification to the glucose-fructose oxidoreductase gene resulting in reduced expression of GFOR enzyme activity. The engineered strain exhibits reduced production of xylitol, a detrimental by-product of xylose metabolism. It also consumes more xylose and produces more ethanol during mixed sugar fermentation under process-relevant conditions.
