A new sorbent was designed ob the basis of ion exchangers selective for proteins and tannins that form the colloidal haze of beer.For a better promotion of that sorbent in the market, a simple and unexpensive method of operational application was proposed and launched.The process done until now applies dosage of sorbent into the beer flow and its capture on filter.This solution is cost in construction and sanitary demanding.The sorbent is mechanically stressed and crushed and the fine participles pass through the filter screen.

The passing particles are to be captured by another filter which makes the process even more expensive.The company Amersham Pharmacia Biotech lent its pilot unity for testing into the Velke Popovice Brewery.The article describes the results of operational tests performed on that equipment.The following criteria were monitored anthocyanogens, polyphenols, sulfate test, haze, proteins determinated by the Comassie Briliant Blue method, total nitrogen by the Kjeldhal method, bitter substances and the original degrees.Fresh samples, as well as samples after 3 and 6 months were tasted and simultaneously their clarity motovox scooter parts was traced by means of nephelometric measurement of trouble.

The test result have confirmed that the designed ion-exchanger stabilization represent an interesting alterative of the colloid stabilization of beer.A new sorbent was designed ob the basis of ion exchangers selective for proteins and tannins that form the colloidal haze of beer.For a better promotion of that sorbent in the market, a simple and unexpensive method of operational application was proposed and launched.The process done until now applies dosage of sorbent into the beer flow and its capture on filter.This solution is cost in construction and sanitary demanding.
