Abstract Sweetening agents for human and animal foods in the solid or liquid states contain at least 50% by weight of leucrose. They may additionally contain one or more sweetening agents selected from the group consisting of artificial sweeteners and sugar surrogates. The leucrose is produced by reaction of saccharose with α-(1-6)-glucosyl transferase in the presence of at least 100 mmoles of fructose per 1,000 I.U. of enzyme, and at least a partial separation of the dextrans and iso-malto-oligosaccharides. Leucrose may be prepared by this method having a purity of at least 98% and may be used as a non-cariogenic, metabolically fully utilizable sweetening agent with good compatibility which is also suitable for diabetics.
A process for producing leucrose having a purity of at least 50% by weight, characterized in that saccharose is reacted with α-(1-6)-glucosyl transferase in the presence of at least 100 mmoles of fructose per 1,000 I.U. of enzyme, and the dextrans and iso-malto-oligosaccharides are at least partially separated.

A process for producing leucrose having a purity of at least 50% by weight, characterized in that saccharose is reacted with α-(1-6)-glucosyl transferase in the presence of at least 100 mmoles of fructose per 1,000 I.U. of enzyme, and the dextrans and iso-malto-oligosaccharides are at least partially separated.
Claim 3

The process according to claim 1, characterized in that, in order to increase the purity to at least 95% by weight, the leucrose is chromatographically separated from the fructose and the iso-malto-oligosaccharides.
