The best enzymes for liquefaction in distilling

To begin the distilling process, we need to make our solid starch into liquid mash, so the yeast has the best working conditions and it doesn't get stuck in the process. No matter which production facilities you are operating, enzymes can help get the mash ready. Alpha amylase enzymes help cut the complex carbon structure into smaller pieces and thereby making it a liquid ready for further saccharification/SSF.

To find out all there is to know about how enzymes can benefit you distilling process check out the topics below.

Are all Alpha amylase enzymes for distilling the same? 

No, the best are optimized for distilling and have the following properties:

  • Higher ethanol yield: The best enzymes for liquefaction and saccharification maximize starch and dextrins conversion to sugars for yeast fermentation to ethanol. The result is higher ethanol yield, the reason is that it optimizes the whole production process and solves problems that might arrive. 

  • Wide pH range tolerance: Allows you to get more out of your mash and reduces the need to adjust pH levels (less work, problems, cost, chemicals and wider pH range)

  • Lower viscosity: You want to have a high level of dry solids and at the same time keep a production without problems like channelling the mash through the stirred tanks and reduce ware of pumps, heat exchangers, jet cookers and agitation all run better at low viscosity. This is possible to obtain with our best-in-class alpha amylases. 

  • No-jet-cooking: No problem, with aggressive enzymes you still get hydrolysis and high viscosity reduction

  • More efficient conversion: You get 0,5-5% more alcohol, use 20% less CO2 with more efficient enzymes and it all adds up to less cost for the same output

  • The Maillard reaction: With lower pH you lose less sugars to the Maillard reaction and therefore get more alcohol

  • Thermostable: Quality enzymes still perform well at high temperatures (even at 95°C)

  • Infection: Low risk of infection because of low pH and high temperature tolerance

  • Faster: Work up to double as fast

  • Better: Convert up to double as many starts

  • Organoleptic: Increased organoleptic properties with best-in-class enzymes.

  • Equipment: Less wear and investment in equipment

There is a big difference between natural and low quality, compared to optimized Alpha amylase enzymes. Basically, you get less problems and use less time in the production, need less equipment, save energy and money, get a bigger output in higher quality.

 

How to use enzymes for liquefaction in distilling

There is a lot of science that goes into developing and producing the best liquefaction enzymes, but it is straightforward to use it. You just mix liquefaction enzymes directly into the slurry tank / mixing tank. Make sure the temperature and pH are optimized for the enzymes used.

Which kind of enzymes work best for my starch?

The enzymes work on all starch. Different grains have different characteristics and accessibilities of starch.

Storage

The ideal storage conditions is in sealed packaging, in a dry environment, protected from the sun and in cool conditions (0–10°C/32–50°F). Just put it in the fridge.

Extended storage and/or exposure to adverse conditions such as higher temperatures or increased humidity may lead to a higher dosage requirement. The best enzymes can handle more extreme exposure without losing significant effect. 

Dosage

As you probably know, enzymes aren’t alive and therefore don't grow. Therefore, you need enough enzymes to convert the starch to fermentable sugars, so it is easy to digest for the yeast and move easily through the factory. Depending on the quality and the concentration of the enzymes you may need a different amount.

You don’t have to be a scientist to use enzymes, you just need to add it. Don’t take our word for it. Get free enzymes, expert advice and test it for yourself.
