Enhanced liquefaction

Native starch is only slowly degradable by means of alphaamylases, which is why gelatinization and liquefaction of a 30-40% dry matter suspension are needed for enzymatic starch break down. A good liquefaction system is vital for successful presaccharification. In liquefaction, an efficient temperature stable a-amylase is added to the starch milk. Mechanical liquefaction may be achieved using stirred tank reactors, continuous stirred tank reactors (CSTR) or a jet cooker.


Reduced processing costs
Increased plant profitability
Greater starch conversion
Higher alcohol output
More “forgiving” liquefaction process
Termamyl SC is a remarkable new liquefaction enzyme which can operate at lower pH and calcium levels than conventional thermostable alphaamylases
Efficient and quick saccharification
In the production of alcohol and spirits, the saccharification enzymes degrade gelatinised starch and dextrins into fermentable sugars. These sugars are then converted or fermented by the yeast cells into alcohol.

The application of saccharification enzymes has made it possible for dextrins to be efficiently and quickly converted into fermentable sugars.
The characteristics and design of most modern saccharification enzymes ensure the following benefits:

Efficient degradation of dextrins
High alcohol yields
Reduced risk of infection due to high temperature (65°C)
Reduced risk of infection due to low operating pH
Reduced starch losses
Low treatment costs and dosages
Optimum fermentation enhancement
In the production of beverage alcohol and spirits, the steps role in optimum fermentation. Fermentation enhancement can be achieved by individual enzyme preparations or combined preparations, which also simultaneously ensure saccharification.The benefits of using single or combined enzyme preparations for fermentation enhancement are:


Increased alcohol quality
Increased organoleptic properties and no off-flavours
Enhanced and shorter fermentation
Optimum alcohol yields
Minimised losses of residual starch and sugars
A guarantee that fermentation and the production process will always run smoothly and efficiently
Increased savings due to less fouling and the need to clean equipment
