Novozynes Lumista® Gold reduces the amount of haze-active proteins, increasing the colloidal stability of beer while leaving all other properties unchanged. Lumista® Gold consists of a proline-specific endopeptidase that acts on proteins rich in proline residues, preventing the formation of the large haze-active structures. As a result you will see a a significant decrease of visible haze in beer. This highly specific enzyme activity enables the brewers to produce a clear and stable product throughout shelf life.

The sustainable way to make your beer shine

A clear beer throughout shelf life

The formation of molecular structures composed of proline-rich proteins and polyphenols is regarded as one of the major contributors of the haze formation in beer. With time, the size and stability of these protein-polyphenol complexes grow, resulting in increased beer turbidity. In a worst-case scenario, these particles become visible to the naked eye, diminishing the consumer appeal of the final product.

Lumista® Gold comprises a proline-specific endopeptidase that targets haze-active proteins rich in proline residues. By preventing the formation of sizable haze-active structures, it notably reduces the visible haze in beer. This highly specific enzyme activity enables the brewers to produce a clear and stable product throughout shelf life.

Performance

What is haze in beer?

In beer, a variety of insoluble particles can be suspended in the liquid phase, which will scatter the light and make the beer appear turbid. Turbidity in beer can be directly measured with a turbidimeter equipped with detectors placed at a 25° and/or 90° light scattering angles, allowing the detection of very small particles (under 1 μm) with high sensitivity.

Chill and tannic acid-induced haze measurements are commonly used in breweries to assess the potential haze formation during shelf life. Chill haze analysis is a robust method which gives an indication of the maximum potential haze formation caused by the complexes that precipitate under cold conditions and/or by ethanol addition. Tannic acid-induced haze correlates with the level of haze-sensitive proteins present in the matrix.

How to decrease the haze formation in your beer?

Lumista® Gold is the solution for haze prevention in your beer. This highly specific endopeptidase neither affects the fermentation performance nor the sensory profile or foam stability of your beer, keeping it clear (Fig. 1). The addition of Lumista® Gold during fermentation decreases both chill and tannic acid-induced haze values considerably, as shown in Fig. 2.

Traditionally, beer stabilization requires a deep cooling step and is based on the binding and/or precipitation of proteins or polyphenols to avoid the formation of large protein-polyphenols in the finished beer. Applying synthetic adsorbents during maturation and/or filtration may bear the risk of carrying over traces to the finished beer. With an enzymatic solution, breweries can abandon or limit the usage of adsorbents. In addition, the maturation time can be shortened since the enzyme is active throughout the fermentation process.

The impact of Lumista® Gold on beer stability is also evident when following real-time shelf life (Fig. 3). After storing beer samples for 12 months at room temperature, the turbidity and chill haze levels were significantly lower when Lumista® Gold was added (green line, Fig. 3A and 3B). In addition, the foam stability remained unchanged and within standard values (≥ 220 seconds), demonstrating the high specificity of this endopeptidase.

Gluten Reduction

In barley and/or wheat-based beers and beverages

Most commercial beers and malt-based beverages are based on gluten-containing grains such as barley or wheat, preventing their consumption by people on a low or free gluten diet. Upon ingestion of foods or beverages based on barley or wheat, gluten degradation is minimal through the digestive system since the gluten matrix is very resistant to human gastrointestinal peptidases. A major reason for this resistance is the high level of proline in the composition of the gluten proteins. Applying the proline-specific endopeptidase Lumista® Gold leads to a reduction of the gluten content in beer, by cleaving the proteins and peptides rich in proline which constitute a major part of the gluten matrix. When considering a standard pilsner beer based on 100% malt, Lumista® Gold can reduce the gluten content up to 90%, reaching a level below 20 ppm (Fig. 4).

Fig. 4 – In beers based on gluten-rich cereals, Lumista® Gold can decrease the gluten content by 90% (A). Breaking down the proline-rich gluten matrix enzymatically can lead to gluten levels below the 20 ppm threshold (B).

Applying the proline-specific endopeptidase Lumista® Gold leads to a reduction of the gluten content in beer, by cleaving the proteins and peptides rich in proline which constitute a major part of the gluten matrix. When considering a standard pilsner beer based on 100% malt, Lumista® Gold can reduce the gluten content up to 90%, reaching a level below 20 ppm (Fig. 4).

The gluten content in the finished product and remaining allergen potential depends on the raw materials and production process used and therefore, the finished product must be carefully assessed by the produced. The legislation on gluten reduction is highly specific per country or region. Please consult a Lumista® Gold expert for advice before testing this solution for gluten reduction

Usage

Lumista® Gold is dosed into the cold wort at the beginning of the fermentation process. The dosage may vary depending on the wort composition, original gravity and intended shelf life.

The recommended dosage for preventing haze formation in a 100% barley malt beer with 12° Plato is 1.7 g/hL cold wort. In the cases where the main application is gluten reduction, higher dosages may be required: 2.0 – 4.0 g/hL cold wort
The optimal dosage is reached when the finished beer remains clear during the intended shelf life

Lumista® Gold interacts with its environment, so the results are not only pH- and temperature-dependent, but also linked to yeast strain, wort composition and original gravity. Thus, each application needs to be assessed and optimized individually.

More information can be found in the “Brewing Handbook”.

Best before: You will find the best-before date in the certificate of analysis or on the product label. The product gives optimal performance when stored as recommended
and used prior to the best-before date.

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:

Avoid breathing dust/fume/gas/mist/vapors/spray
Avoid contact with eyes, skin, or clothing
