gave inferior yields on these acceptors. The regioselectivity was acceptor dependent and primarily involved beta-1,4 or 1,6 product linkage formation although minor products with different linkages were also obtained. Five of the 18 transxylosylation products obtained from D-lyxose, D-galactose, turanose and sucrose (two products) as acceptors were novel xylosyl-oligosaccharides, beta-D-Xylp-(1-->4)-D-Lyxp

The present invention relates a method of producing turanose using amylosucrase and a sweetener including the turanose. This method enables production of high-purity turanose through an enzymatic reaction occurring by treating a solution including only sucrose or a solution including fructose and sucrose with amylosucrase.

Selectiveactivation of the ketose unit in the isomericglycosylfructoses, palatinose, leucrose, maltulose, turanose and lactulose, with pyridinium poly(hydrogenfluoride) resulted in the almost quantitative formation of glycosylated difructose dianhydrides. The reaction preferentially involves a reactive fructofuranosyl oxocarbenium ion and is subject to stereoelectronic control. The relative amounts
