Abstract
The present invention relates to a method of producing maltose syrup, wherein starch is treated with a hexosyltransferase (E.C. 2.4.1) and then a beta-amylase and/or a maltogenic amy-lase, or variant thereof. The invention also relates to an intermediate product suitable as staring material in maltose production processes.
Claims17
A method of producing maltose, wherein starch is treated with
- i) a hexosyltransferase (E.C. 2.4.1), and then
- ii) a beta-amylase (E.C. 3.2.1.2) and/or a maltogenic amylase (E.C. 3.2.1.133), or variant thereof.
The product obtainable by treating starch with a hexosyltransferase (E.C. 2.4.1) until a product having
- i) an Additional Degree of Branching (ADB) of between 10-150% has been provided if using a branching enzyme, and/or
- ii) a viscosity corresponding to that of liquefied starch obtainable by treating 30% DS starch with wild type Bacillus licheniformis alpha-amylase until a DE in the range from 8-15, preferably DE of between 10-12, has been provided.
