Key Benefits:

Increased adjunct inclusion

Adjuncts like corn, rice and sorghum starch have high gelatinization temperatures. Malt α-amylases become inactive at these temperatures. The result is inconsistent with starch degradation. That limits the proportion of these adjuncts you can include in your beers. This thermostable product delivers consistent liquefaction at high temperatures. That means you can increase adjunct inclusion in your beers.

Increased brewhouse capacity

The exceptional power of this liquefaction product allows for thicker mashes without the risk of high viscosity. You can use this versatility to increase the capacity of your brewhouse.

Consistent extract yield

A liquefaction step that uses only malt enzymes can lead to inconsistent starch degradation. This in turn leads to inconsistent extract yield. This heat-stable product delivers consistent liquefaction at high temperatures.

Flexible high gravity brewing

This product delivers the viscosity reduction you need to run your process at high grist. That allows you to reap the benefits of high-gravity fermentation. These include reduced energy and water consumption.

Potential energy savings

Decoction mashes are typically heated to a peak of 100°C.
That's partly so the physical action of boiling can break down starch molecules. This thermostable product degrades starch at 90°C to allow lower peak temperatures in your decoction vessels. Handling decoction mashes at lower temperatures leads to potential energy savings.

Cost-effective cereal cooking

For high-gelatinizing adjuncts, a separate cooking step during mashing is required to secure sufficient gelatinization and liquefaction. Due to lower stability of malt α-amylases at the gelatinization temperatures of corn, rice and sorghum starch, a liquefaction step that uses only malt enzymes can lead to inconsistent starch degradation. This can result in several process and quality issues such as lower yields, less efficient wort separation and a haze increase in the final product.

Novozymes Termamyl® products are heat-stable amylases that offer easy and consistent liquefaction at high temperatures, providing many benefits and preserving full malt enzyme potential for the main mashing process.


● Faster and more consistent liquefaction
● Lower mash viscosity, resulting in easier wort production
● No risk of resistant or retrograded starch formations, or insufficient saccharification
● Reduced processing costs through more efficient liquefaction, increased yield of up to 1%
● Improved flexibility of use of various cereal grain adjuncts
● Reduced energy consumption due to lower temperatures when handling decoction mashes


Starch-containing adjuncts and cereals must be processed in such a way that the starch is gelatinized and liquefied. Gelatinization refers to the swelling of the starch granules, whereas liquefaction is the de-branching process that breaks down the intermolecular bonds of starch (both amylose and amylopectin) in the presence
of excess water and applying heat in order to take up more water—this is also known as hydrolysis. The gelatinization process is necessary for liquefaction to reduce viscosity and to make starch susceptible to the enzymatic hydrolysis taking place during saccharification with malt enzymes and/or exogenous enzymes.

Liquefaction with Termamyl® is a simpler and faster process than liquefaction with malt enzymes. Termamyl® reduces cereal mash viscosity, thereby preventing the formation of retrograded starch. This secures the yield when using adjuncts as the liquefaction material as opposed to malt. The yield can be increased by more than 1%. While it is necessary for the malt α-amylase to work at its limit for temperature stability, Termamyl® maintains very high stability throughout the temperature ranges applied.

In addition to the aforementioned benefits, Termamyl® also enables manufacturers to lower the peak temperature of decoction vessels. Traditional decoction mashes are heated up to 100°C not only for gelatinization, but also to use the physical forces at this temperature to break down starch molecules. The thermostable α-amylases in Termamyl® already secure sufficient starch degradation at 90°C, making further temperature increases obsolete.

Figure 1 illustrates a normal mashing regime using a cereal cooker, with the addition of Termamyl® instead of malted barley. In figure 2, a normal viscosity graph is shown during the cereal cooking process, peaking during gelatinization.

Termamyl® is also a versatile solution in terms of mash thickness due to its exceptional liquefaction power, which is approx. 200–300 times higher per kg than that of malt. Thicker mashes can be operated without the risk of working with high viscosities.

This, in addition to the fact that 100 kg of malt is replaced by 0.2 kg Termamyl® SC DS, enables smaller mashes, which is invaluable when balancing volumes and temperatures while working with high proportions of adjuncts. This versatility can also be used to increase brew house capacity. In addition to the benefits of working with thicker mashes, the malt is replaced by adjuncts with higher extract values.

The process is also more cost-effective, as all the malt can be used in the main mash. This safeguards the mashing operation and provides improved wort, which reaches the correct and higher side of the desired attenuation range and has an increased FAN content.



The amount of Termamyl® added during mashing-in depends on adjunct material and quality.

 Dosage [kg/ton of adjunct] Ca2+ requirements
Termamyl® SC DS 0.15–0.25 no dependency



Using higher amounts of adjuncts (>20%) may result in worts with insufficient free amino nitrogen (FAN). This can be counteracted by using a protease such as Neutrase® 0.8 L in the malt mash to extract more nitrogenous compounds from the malt.


Termamyl® can be deactivated during a typical wort boil.
