Abstract:
The invention relates to methods for producing flavour stable beverages. The methods involve reducing the level of one or more amino acids, and in particular the level of methionine. The level of amino acids may be reduced by a number of different methods, for example by increasing the level of acid or base and removal of said acid or base by Reverse Electro-Enhanced Dialysis. The level of amino acids may also be reduced by treatment with an oxidizing agent, such as H 2 O 2 . The invention also comprises combinations of such methods.

Abstract:
A calibration method comprises the steps of providing a beverage dispensing system (10) including a pressure chamber (12) with a removable lid and defining a first inner volume (14). The pressure chamber (12) is fluidly connected to a pressurization system (42), which supplies a specific volume of gas per operating cycle to the first inner volume (14). The pressure chamber (12) further has a pressure sensor (46) for sensing the pressure of the first inner volume (14). The calibration method further provides a collapsible beverage container (16) with a second inner volume of beverage being smaller than the first inner volume (14). The calibration method still further comprises the steps of opening the lid, introducing the beverage container (16) into the first inner volume (14), increasing the pressure value from a predetermined low pressure value to a predetermined high pressure value, determining the number of operating cycles, and establishing a measure of the specific volume of gas per operating cycle.
Abstract:
A system for externally cooling a beverage holder holding a specific amount of beverage comprises a cooling housing having an inner wall and an outer wall. The inner wall is made of thermal conductive material for contacting at least a part of the beverage holder. The cooling housing defines an inner compartment including at least two separate, substantially non-toxic reactants, causing when reacting with one a other a non-reversible, entropy-increasing reaction producing substantially non-toxic products in a stoichiometric number. The at least two separate substantially non-toxic reactants are initially included in the inner compartment separated from one another and causing, when reacting with one another in the non-reversible, entropy-increasing reaction, a heat reduction of the beverage within the beverage holder. The system further comprises an actuator for initiating the reaction between the at least two separate, substantially non-toxic reactants, and an insulating layer of thermal insulating material enclosing the cooling housing.
Abstract:
A beverage dispensing assembly comprises a beverage storage area, a beverage tapping area and a beverage distribution python extending between the beverage storage area and the beverage tapping area. The beverage distribution python comprises a liquid carrying line defining a centre line. The liquid carrying line comprises a beverage tube and/or a beverage guide tube. The beverage distribution python further comprises a pipe covering the liquid carrying line in a coaxial relationship to the centre line and establishing a space in-between the pipe and the liquid carrying line. Still further, the beverage distribution python comprises an insulation layer located in the space between the pipe and the liquid carrying line and encircling the liquid carrying line. The insulating layer comprises at least 80% aerogel by volume.
Abstract:
A cooling device comprises a housing including a first reactant and a second reactant. The first and second reactants are substantially non-toxic and causing, when reacting with one another, a non-reversible, entropy increasing reaction producing substantially non-toxic products in a stoichiometric number at least a factor 3, preferably at least a factor 4, more preferably at least a factor 5, larger than the stoichiometric number of the reactants. The first reactant is initially separated from the second reactant by a dissolvable or deterioratable polymeric coating and a dissolvable or deterioratable hydrophobic coating. The polymeric coating and the hydrophobic coating each completely encapsulate at least one of the first reactant and the second reactant. The housing further includes an actuator for initiating the reaction between the first reactant and the second reactant by at least partially dissolving or deteriorating the polymeric coating and the hydrophobic coating.
Abstract:
A bottle, container or beverage glass for containing a hops based beverage, in particular beer, includes a concentration between 10 μg/l and 10 mg/l of Riboflavin. The bottle, container or beverage glass are at least partially transparent or translucent to visible light and have an optical filter characteristic preventing light transmission at the wavelength intervals 220-230 nm, 250-270 nm, 350-370 nm and 440-450 nm to a level preventing generation of more than a tasteable concentration of MBT in the beverage through photochemical reactions and photochemically initiated auto-catalytic reactions involving the Riboflavin. The tasteable concentration is between 1 ng/I and 35 ng/l, preferably between 5 ng/l and 25 ng/l, and more preferably 10 ng/l.
Abstract:
A self regulating and constant pressure maintaining beverage dispenser assembly comprises a dispensing device and a beverage container defining an inner space constituting a beverage space filled with carbonated beverage and communicating with the dispensing device for allowing dispensation of the carbonated beverage, and a head space communicating with the beverage space and filled with CO 2 having an initial pressure of 0.1-3 bar above the atmospheric pressure when subjected to a specific temperature of 2°C-50°C preferably 3°C-25°C and more preferably 5°C-15°C. The beverage dispenser assembly further comprises at least one carbonisation canister communicating with the head space via a hydrophobic labyrinth and comprising a particular amount of adsorption material having adsorbed a specific amount of CO 2 . The particular amount of adsorption material is inherently capable of regulating the pressure in the head space and of preserving the carbonisation of the carbonated beverage in the beverage space by releasing CO 2 into the head space.
Abstract:
A valve element of a beverage dispensing assembly to be used with a tapping head includes a tapping head housing and a tap handle. The beverage dispensing assembly comprises two elements, viz a dispensing line having a dispensing end and a keg connection end, and the valve element comprising an upstream valve part, a flexible valve part, a lower valve part, and a plug being accommodated in the lower valve part and serving to seal off the dispensing end of the dispensing line. When the valve element is not positioned and received in the tapping head housing, the plug is caused to seal off the dispensing line, and when the valve element is positioned and received in the tapping head housing, the upstream valve part and lower valve part of the valve element are operated by the tap handle for causing the plug to seal off the dispensing line.
Abstract:
According to the invention, there is provided barley with total loss of functional lipoxygenase (LOX)-1 and LOX-2 enzymes, and plant products produced thereof, such as malt manufactured by using barley kernels defective in the synthesis of the fatty acid-dioxygenating enzymes LOX-1 and LOX-2. Said enzymes account for the principal activities related to dioxygenation of linoleic acid into 9- and 13-hydroperoxy octadecadienoic acid,respectively. 9-Hydroperoxy octadecadienoic acid represents a LOX pathway metabolite, which - through further enzymatic or spontaneous reactions - may lead to the appearance of trans-2-nonenal (T2N). The invention enables brewers to produce a beer having insignificant levels of stale,T2N-specific off-flavors, even after prolonged storage of the beverage.
