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.
Benefits
- 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.
Benefits
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: Benefits
- 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
