Abstract
Acylation ofBacillus stearothermophilus α-amylase was investigated for the purpose of producing a reduced stability, malt-like α-amylase. Acylation with acetic, propionic, or butyric anhydrides resulted in formation of derivatives with substantially reduced thermal stability. Acylation with other anhydrides was not as effective in reducing the thermostability of the enzyme. Measurement of the Brabender viscosity of unmalted flour supplemented with acetylatedBacillus stearothermophilus α-amylase indicated that the acetylated enzyme yielded viscosity reductions similar to those seen with flour that had been supplemented with malt.
