Abstract
The present disclosure relates to liquid enzyme formulations containing one or more alpha-amylases for use in starch processing, wherein the pH of the enzyme formulation is about pH 6.0-8.0, and methods of use thereof. The present disclosure further relates to methods of making a liquid enzyme formulation containing one or more alpha-amylase having improved stability, comprising titrating the pH of the liquid enzyme formulation to a range of pH 6.0-8.0.
Claims18
A liquid enzyme formulation comprising:
- (a) an alpha-amylase;

- (d) a preservative,
- wherein the pH of the enzyme formulation is about pH 6.0-8.0.
3 more elements
A method of making a liquid enzyme formulation comprising:
- (a) providing a composition comprising an alpha-amylase, wherein the composition has a pH value of about 8.0 to about 10.5;
- (b) adding a stabilizer to the composition comprising the alpha-amylase to obtain a liquid enzyme formulation;
- and
- (c) titrating the pH of the liquid enzyme formulation to a range of pH 6.0-8.0.
1 more element
Use of a liquid enzyme formulation, comprising:
- (a) providing a liquid enzyme formulation comprising an alpha-amylase, a buffering agent, a stabilizer, and a preservative, wherein the pH value of the liquid enzyme formulation is about pH 6.0-8.0;
- (b) providing a starch;
- and
- (c) contacting the liquid enzymatic formulation with the starch, thereby hydrolyzing the starch.
