Document Type and Number:
WIPO Patent Application WO/2013/114223
Kind Code:
A3
Abstract:
The present invention relates to a process for producing a syrup which is rich in maltitol. The process is comprising the successive steps of liquefaction of a starch milk and saccharification of the liquefied starch milk in the presence of alpha-amylase, beta-amylase and a debranching enzyme selected from the group of pullulanase, iso-amylase and mixtures thereof, preferably pullulanase and further adding maltogenic alpha-amylase and/or iso-amylase, for obtaining a maltose containing syrup comprising at least 85% maltose based on dry matter and less than 1.5% glucose based on dry matter, preferably less than 1 % glucose based on dry matter, followed by molecular sieving of the maltose containing syrup to obtain a fraction (A) comprising at least 95% maltose based on dry substance of fraction (A), and further hydrogenating catalytically fraction (A) for obtaining a liquid maltitol enriched product (B).
