Abstract
A process for preparing a stable liquid enzyme concentrate containing the alpha-amylase from Bacillus stearothermophilus. A commercial alpha-amylase enzyme preparation is treated with granular starch to absorb the enzyme, and the starch containing the enzyme is separated and then heated in a buffer solution containing calcium ion. The resulting solution, separated from insoluble solid, is then concentrated to give the final product.
