LIQUEFACTION OF GRANULAR-STARCH SLURRIES USING ALPHA-AMYLASE IN THE PRESENCE OF CARBONATE ION

摘要

A starch slurry is liquified with alpha-amylase to produce fructose by a process wherein carbonate ion in excess of an amount needed to adjust the pH to about 5.0 to 6.0 is added to the slurry and the pH of the slurry is adjusted to about 5.0 to 6.0. The excess amount is preferably about 2 mM to 20 mM. This process enables obtaining consistent and complete liquefaction.
