Enzymatic formulation to improve the colloidal stability of beer.
Siligel S (25 Kg)
Reference:
Protein stabilizer for beer based on moisture-controlled silica gel.
Siligel S is a beer stabilizer with a selective absorption action for protein substances, made up of a very pure silica gel with controlled humidity.
Protein stabilizer for beer based on moisture-controlled silica gel.
Siligel S is a stabilizer for beer with a selective absorption action for protein substances, made up of a very pure silica gel with controlled humidity.
The surface area of Siligel S is very high: this ensures the product peculiar physical-absorbent properties.
Siligel S allows to maintain the correct content of protein nitrogen, with respect to the raw materials used, the production system and the specific experience of the brewery technician.
Very high values of protein nitrogen cause reactions of colloity instability, while low values can give problems of persistence and stability of the foam.
Siligel S has a selective power in the absorption of proteins, affecting in a lesser way those of medium-high molecular power, which play an important role in the formation and persistence of the foam. Up to 50 g / hL, Siligel S has no effect on foam stability.
The colloidal turbid, which is formed in cooled beer by reactions between protein-polyphenolic substances, is effectively absorbed in the Siligel S-Beer contact phase.
Siligel S has no negative effect on the color, pH and organoleptic characteristics of the treated beer.
The permeability of Siligel S does not affect the evolution of pressure in the filtration, this being more characteristic in the use of a traditional xerogel.
Composition and technical characteristics:
Silica gel.
Employment dose:
10-100 g / hL.
The lower doses are used in treatments that involve a longer contact time Siligel S-beer or for more mature beers.
Form of employment:
Siligel S can be used in the various phases of the production cycle.
In deposit: with contact times of a minimum of 15 minutes to 6-24 hours, to later be eliminated in filtration. In this way, less filter earth is used. Siligel S also works as a filter aid.
In filtration: mix Siligel S with the diatoms, in the filter dispenser, and alluvize it in the filtration. Silige S is also effective with very short contact times such as those found in alluvial filtration. In the two systems of use, in the accelerated EBC stability test (60-0-60ºC), a high stabilizing effect is found.
WARNINGS: in the case of using proteolytic enzymes in a combined treatment, it is advisable to add Siligel S in the final filtration, the enzyme can be added to the filtered beer before bottling.
