SUBSTANCE CONTAINING LACTOSUCROSE IN HIGH CONTENT AND ITS PRODUCTION AND USE

Japanese Patent JPH1057092

A

To enable easy and mass production of the subject substance- containing solution by allowing a glycosyltransferase to act on an aqueous solution containing sucrose and lactose and removing contaminant saccharides from the resultant lactosucrose containing aqueous solution.

A glycosyltansferase (for example, fructose glycosy-transferase) is allowed to act on an aqueous solution containing sucrose and fructose. Then, the contaminants are removed from the resultant lactosucrose-containing saccharide solution, preferably by alkali or alkaline earth metal type storing acid cationic ion-exchange resin column chromatography using only water to give a solution containing more than 45w/w% of lactosucrose and the solution is collected. usually, the glysyltransferase is allowed to act on an aqueous solution containing sucrose and lactose at a ratio of 1/10-10/1 in the total saccharide concentration of 10-60wt.% at a pH of 3-9 and a temperature of 5-70°C.
