Patent No. WO2012011807A1: A Method Of Stabilising Yeast Fermented Beverages

By

patent-logo
Today in 2012, US Patent WO 2012011807 A1 was issued, an invention of Tom Reinoud Noordman, Anneke Richter, and Marcel Van Der Noordt, assigned to Heineken Supply Chain B.V., for their “A Method of Stabilising Yeast Fermented Beverages.” Here’s the Abstract:

The present invention provides a method of preparing a yeast fermented beverage, said method comprising the steps of: a. fermenting wort with a biologically active yeast to produce a fermented liquid containing yeast, alcohol, polyphenols and protein; b. optionally removing yeast from the fermented liquid; c. combining the fermented liquid with polyvinylpolypyrrolidone (PVPP) particles to bind at least a fraction of the polyphenols and/or the proteins contained in the fermented liquid to said PVPP particles, at least 80 wt.% of said PVPP particles having a diameter in the range of 5-300 µm; d. removing a slurry containing the PVPP particles from the fermented liquid; e. filtering the slurry over a filter having a pore size in the range of 0.1-80 µm to produce a PVPP-enriched retentate and a PVPP-depleted filtrate; f. regenerating the PVPP particles contained in the PVPP-enriched retentate by desorbing polyphenols and/or protein from said PVPP-particles and separating the desorbed polyphenols and/or the desorbed protein from the PVPP particles; and g. after optional further refining of the regenerated PVPP particles, recirculating the regenerated PVPP particles to step c. The method can be operated with single use PVPP as well as regenerable PVPP. Furthermore, the present method does not require capacious filter hardware for regenerating the PVPP. The invention further provides an apparatus for carrying out the aforementioned method.

Patent No. 5384135A: Process For The Manufacture Of An Alcohol-Free Beer Having The Organoleptic Properties Of A Lager Type Pale Beer

By

patent-logo
Today in 1995, US Patent 5384135 A was issued, an invention of Henri J. J. Caluwaerts, assigned to Brasserie Du Cardinal Fribourg S.A., for his “Process for the Manufacture of an Alcohol-Free Beer Having the Organoleptic Properties of a Lager Type Pale Beer.” Here’s the Abstract:

A process for the manufacture of an alcohol-free pale beer (AFB) whose organoleptic properties are those of a lager beer, comprising the manufacture of a lager type alcoholic pale beer from pale malts containing 20 to 30% of brown malts, mashed to obtain a wort whose attenuation is of the order of 50% and the dealcoholization of the alcoholic pale beer, by evaporation, under high vacuum, of at least about 50% of the volume of this beer. The concentrate obtained by evaporation may be rediluted with water, flavored and sweetened until a concentration of 4° Brix is obtained in order to produce the AFB. The concentrate may also be subjected to a second vacuum evaporation at a temperature of less than 60° C. until a concentrate assaying between 45° and 65° Brix is obtained which is storable for several months before the redilution into an AFB.

Patent No. 4070133A: Pump Compressor Unit For Use With Pumping Draft Beer

By

patent-logo
Today in 1978, US Patent 4070133 A was issued, an invention of Homer McCormick, for his “Pump Compressor Unit for Use with Pumping Draft Beer.” Here’s the Abstract:

An air supply unit provides high pressure moisture-free air in the dispensing of beverages. Components are housed in a portable cabinet and include a compressor and an automatic air pressure switch to switch on the compressor and begin air flow when system pressure falls below a pre-set level. A check valve is located in the high pressure line adjacent the compressor to maintain line pressure when the compressor is off. A small air bleed opening is located between the check valve and the compressor to allow compressed air to move through the air line yet bleed residual pressurized air to prevent stalling of the compressor which could occur if high pressure air was present in the compressor when it is restarted. The high pressure air discharge line includes a dump-check valve to permit high pressure air to be manually bled from the system before the air lines are disconnected and to prevent back flow of fluid into the air supply unit.
