Patent ID: 7919294

Claim:
A process for preparing a stabilized and partially dried enzyme composition, comprising: a) bringing into contact in a single container: i) an aqueous reaction mixture comprising at least one enzyme for an enzymatic reaction and all or part of the reagents which are necessary for carrying out said enzymatic reaction; and ii) an aqueous stabilizing mixture comprising: at least one protective agent against drying selected from the group consisting of melezitose and raffinose; at least one inhibitor of a condensation reaction between carbonyl or carboxyl groups and amine or phosphate groups selected from the group consisting of betaine and lysine; and at least one inert polymer capable of generating a mesh structure preventing the mobility of the dried reagents which is glycogen; to produce a liquid phase aqueous mixture comprising said reaction mixture and said stabilizing mixture; and b) subjecting said liquid phase aqueous mixture to a temperature of 10° C. to 60° C., at a pressure lower than atmospheric pressure, to produce a stabilized and partially dried enzyme composition having a moisture content of between 1% and 30%.
