Get to know us

Slow mash separation negatively affects the quality of the wort. That may lead to problems with beer filtering, flavor, and stability. This product delivers a thorough breakdown of beta-glucans and pentosans during mashing. The result is faster wort separation.

Faster wort separation

This product delivers consistent, fast and efficient wort separation. That allows you to maximize your number of brews per day.

Increased brewhouse capacity

By effectively breaking down cell walls, this product allows greater access to the starch. That allows you to achieve higher extract yields.

Benefits

Ultraflo® XL is a classic multi-active beta-glucanase and xylanase preparation. It gives you improved wort separation and beer filtration.

Details

This product contains enzymes. While enzymes are safe to use in consumer applications, they need correct handling in working environments to ensure workers’ safety.

Indeed, repeated inhalation of enzyme dust or aerosols resulting from improper handling may induce sensitization and may cause allergic type 1 reactions in sensitized individuals.

Please follow the precautionary handling recommendations below:

Ultraflo® XL

Ultraflo® XL breaks down unmodified cell walls from barley malt and unmalted barley. That helps level out fluctuations in your brewing raw materials. The result is consistently high brewhouse performance and beer filtration rates.

Glucans and arabinoxylans absorb water, making the wort viscous and slowing filtration. They also stop enzymes from breaking down starch. That leads to lower yields and haze in the final beer. Filtration enzymes hydrolyze glucans and arabinoxylans to polysaccharides. The result is faster, more efficient separation and filtration.

 
The cell walls of barley and other cereal grains contain mixed-linked 1,3-1,4 β-glucans and arabinoxylans. These have a high molecular weight, which impacts the efficiency of separation and filtration. 

The amounts and ratios of these molecules differ from grain to grain. Barley, oats and sorghum have more β-glucan molecules than xylan molecules. The ratio is more than two to one. Wheat and rye have the opposite ratio, with more than twice as much xylan as β-glucan. 

β-glucans and arabinoxylans are very hygroscopic; they absorb water. That makes the wort very viscous and dramatically reduces mash filtration speed. When they absorb water, β-glucans and arabinoxylans also become greasy. That makes them stick to other grain components and to filter aids and membranes. They can also stick to starch molecules, making starch less available for enzymatic degradation. That can lead to lower brewhouse yields and haze in the final beer. 

Filtration enzymes hydrolyze mixed-linked 1,3-1,4 β-glucans and arabinoxylans to polysaccharides. Unlike malt enzymes, thermostable filtration enzymes can withstand high temperatures. That means they stay active during the entire mashing. The result is faster, more efficient wort separation and beer filtration.

How enzymes improve wort separation and beer filtration in brewing

Beta-glucans and arabinoxylans create high wort viscosity. This slows down mash filtration. This product effectively breaks down glucans and arabinoxylans. The result is lower viscosity and faster beer filtration. That allows for high volumes of beer per filter run.

Faster beer filtration

B-Glucan that hasn&#039;t been broken down by enzymes can appear as haze in your final beer. This product breaks down beta-glucans to reduce haze formation.

Haze reduction in final beer

Applying higher mash-in temperatures (&gt;62 °C) can be beneficial in terms of less staling flavor formation based on lipid oxidation products but also in reducing the duration of the mashing process. This product is efficiently degrading beta-glucan anad arbinoxylan at temperatures up to 80 °C and therefore allows complete flexibilty in designing a well working mashing-process.

Thermostability

Undermodified malt introduces significantly higher concentrations of high molecular beta-glucan and arabinoxylan into the mashing process and requires adjustment of the mashing process and significant increases of dosage of filtration enzymes. The highly effective and thermostable beta-glucanase and arabinoxylanase in this products results in a much more robust performance, reducing the dosage induced cost-in-use increase to a minimum

Consistent performance for undermodified malt

This product's concentrated formulation allows you to reduce your number of deliveries. The result is lower handling costs and an improved sustainability profile.
