Abstract:
1. A method of activating α-amylase, which comprises steps of contacting A) α-amylase or particles comprising α-amylase with B) particles comprising an oxidizing agent and separating, after the contacting step, A) the α-amylase or particles comprising α-amylase from B) particles comprising the oxidizing agent, wherein the particles comprising an oxidizing agent have a diameter of 100 μm to 1500 μm, wherein the ratio of enzyme to oxidizing agent is from 1:10 to 100:1, and wherein the activity of said α-amylase is increased by 20 to 101% as compared to α-amylase which is not contacted with an oxidizing agent, and wherein the activity of the α-amylase particles is maintained after the separation step.
