US 5,296,473 A · Process for preparing a powder having a high concentration of lactosucrose and use of said powder

Abstract

The lactosucrose high-content powder according to the present invention is prepared by allowing an aqueous solution containing sucrose and lactose to act on a saccharidetransferring enzyme, removing concomitant saccharides in the resultant saccharide solution containing lactosucrose to obtain a solution having a high concentration of lactosucrose, i.e. lactosucrose content of 45 w/w % or more of the sugar composition, and spraydrying the resultant solution to obtain a powder having a high concentration of lactosucrose. The powder is incorporated in an orally- or parenterally-administrable product to obtain an orally- or parenterally-administrable product which exerts a selective growth-promoting-effect on a microorganism of the genus Bifidobacterium in vivo.

Claims7

Dependent claims

A free-flowing powder containing a high concentration of lactosucrose having a moisture content lower than about 3% and obtained by the process of:

(a) allowing a saccharide-transferring enzyme to act on an aqueous solution containing sucrose and lactose, wherein the ratio of said sucrose and lactose is in the range of about 1:10 to 10:1;
(b) removing concomitant saccharides from the resultant saccharide solution containing lactosucrose to obtain a solution having a high concentration of lactosucrose with a lactosucrose content of 45 w/w%, d.s.b., or higher based on sugar composition;
and
(c) spray-drying the solution having a high concentration of lactosucrose into a free-flowing powder having a moisture content of less than about 3%.
