How to lower pH

What is liquefaction?

Liquefaction uses heat and alpha-amylase to convert granular starch into starch hydrolysate (DEx) to be saccharified later. With Novozymes, you can run liquefaction at a lower pH, preventing problems and saving costs.

The most efficient liquefaction 

How can enzymes help?

Liquefaction should run efficiently, but sometimes it doesn’t. 

Just a few of the challenges are the cost of chemical inputs and removing them later with ion exchange, incomplete conversion, and iodine-positive issues causing quality and filtration issues 

DE (dextrose equivalent) development in liquefaction is determined by process conditions, enzyme dosage and efficiency. Novozymes’ range of alpha-amylases can optimize the liquefaction process in terms of cost, quality and efficiency under a wide variety of conditions. With LpHera®, you can cut your chemical costs by more than 50%.
