  • a bottle 10 containing an alcoholic beverage 12 has an outlet 14.
  • the device shown generally at 16 is provided with a body 18 which houses filter material 20, so that in use the liquid contents of the bottle have to pass through the filter material 20 when the beverage is poured from the bottle.
  • the body 18 may have an inlet 24 adapted as in this example, for fitting tightly over the neck 22 of a bottle, or alternatively it may be adapted for plugging into the neck 22 of the bottle.
  • the filter 20 is made of materials known in the art which are able to bind proteins. Thus, enzymes and other proteins can be adsorbed onto suitable filter materials by techniques well known in the art.
  • an ethanol- binding reagent is immobilised on the filter 20.
  • the ethanol-binding reagent may be an anti-ethanol, (monoclonal or polyclonal), antibody.
  • Antibodies, and in particular monoclonal antibodies specifically bind and hold their opposite binding members.
  • an anti- ethanol antibody will recognize and hold onto any ethanol it finds in a mixture of other ingredients. Since the antibodies can be highly specific for ethanol, this means that only ethanol will be removed from the beverage. Thus related alcohols and aldehydes will be left in the beverage. This is desirable as these compounds related to ethanol are part of the complex mix of chemicals which endow wines and beers with their full flavour and body.
  • an enzyme may utilise ethanol as a substrate.
  • Such an enzyme will bind its substrate, in this case the substrate being ethanol.
  • the ethanol may or may not, then be broken down, this being controlled by the provision or otherwise of cofactors necessary for the enzymic reaction to proceed.
  • an enzyme which utilises ethanol as a substrate, converting it into acetaldehyde is immobilised on the filter 20.
  • That enzyme may be alcohol dehydrogenase, microsomal ethanol oxidising systems or catalase.
  • a further protein component is also immobilised on the filter (or located adjacent the filter) and functions to bind the acetaldehyde produced by action of the enzyme on ethanol in the beverage.
  • proteins such as haemoglobin, albumin and polylysine may be used, as they spontaneously bind to acetaldehyde.
  • the filter 20 serves the dual purposes of: a) slowing the rate of flow of beverage through the device 16 and b) of physically trapping the enzyme and other protein in the device and ways of achieving these objectives other than by utilisation of conventional membranous or particulate filter materials are also covered by the present invention.
  • aldehyde binding protein is haemoglobin
  • it may be immobilised on the filter.
  • the aldehyde binding protein is polylysine it may be provided in the form of beads which do not require immobilisation on the filter material.
  • Aldehyde binding proteins such as polylysine have a plurality of binding sites for aldehyde and they efficiently 'mop-up' the aldehyde produced by the enzymes action on ethanol. Since enzymes can be highly specific for ethanol, this means that only ethanol will be utilised as a substrate and thereby removed from the beverage.
  • Related alcohols and aldehydes excepting acetaldehyde which will spontaneously bind to the protein component) will be left in the beverage. This is desirable as these compounds related to ethanol are part of the complex mix of chemicals which endow wines and beers with their full flavour and body.
  • synthetic structural analogues of the complete natural molecule or just of the active binding site of an appropriate antibody or enzyme may be used as the ethanol-binding or ethanol-consuming reagent in this devic .
  • synthetic structural analogues of the complete natural molecule or just of the active acetaldehyde binding site may be prepared from an analysis of the acetaldehyde binding proteins such as haemoglobin, albumin or polylysine.
  • Both antibodies, enzymes and synthetic structural analogues thereof are proteins in character and these may be adsorbed onto suitable filter materials by techniques well known in the art.
  • the device 16 as shown is fitted over the outlet 14 of the bottle 10, which may then be inverted to pour out the beverage 12.
  • the beverage 12 thus enters the device via its inlet 24 and then passes through the filter 20.
  • the ethanol-binding reagent immobilised thereon recognises and binds the ethanol.
  • the ethanol-binding reagent is an antibody as described in the first embodiment, the antibody specifically recognizes. and binds the ethanol, thus removing it from the beverage being poured into a glass via the outlet 26 of the device 16.
  • the ethanol-binding reagent is an enzyme which converts the ethanol to acetaldehyde, which is then bound by the protein also immobilised on or adjacent the filter 20. In this way, the ethanol is removed from the beverage being poured into a glass via the outlet 26 of the device 16.
  • the ethanol will be removed from the wine or beer at the stage of final fermentation and prior to bottling.
  • devices 16 bearing the immobilised reagent e.g. the antibody or enzyme systems as described for the first and second embodiments
  • the immobilised reagent e.g. the antibody or enzyme systems as described for the first and second embodiments
  • the devices 16 bearing the immobilised reagent are lowered into vats 30, left in the vats 30 for a time sufficient to allow the binding of, or conversion of ethanol by the ethanol-binding reagents before removal of the devices 16 from the vat 30.
  • the devices can be washed, for example, with isotonic saline to release the bound ethanol, drained with gentle shaking and re-used.
  • the device can comprise one or more glass helices or nylon sheets 32 which are able to immobilise the protein reagents e.g. ethanol-binding reagents. Other materials which can bind proteins • may also be used.
  • protein reagents e.g. ethanol-binding reagents.
  • Other materials which can bind proteins • may also be used.
  • FIG. 3 A further embodiment of the invention is depicted in Figure 3, whereby the final ferment 40 from a vat 30 is passed through two separate columns 42 and 44.
  • the first column 42 comprises the immobilised enzymes as previously described for conversion of ethanol to acetaldehyde.
  • the second column 44 contains a polymeric material (as previously described) which is able to efficiently bind the acetaldehyde produced by the enzymic reactions in the first column 42.
  • the first column 42 may be a continuous action column and the second column 44 may be a disposable cartridge.
  • acetaldehyde By use of a cartridge material used in the second column 44 which can bind the acetaldehyde reversibly (for example, an antibody-based reagent), then the acetaldehyde can be recovered. This would be an additional product from the process and since it is "biologically derived" (as compared to a chemically synthesized) acetaldehyde it may be used as an additive in the food and beverage industry.
  • the final product 46 from this system will be an alcohol and acetaldehyde-free or reduced beverage.
  • FIG. 4 A further embodiment of the present invention is shown in Figure 4.
  • de-alcoholised beverages for example wine are produced by distilling a final ferment 40 from a vat 30 in a still 50.
  • This distillation process produces two fractions, a de- alcoholised beverage 51 and a distillate 52 containing ethanol, flavourings and aroma factors.
  • the flavouring and aroma flavours which impart a wine or beer with their particular characteristics enjoyed by a consumer are lost from the de-alcoholised beverage.
  • the distillate 52 containing the ethanol, flavourings and aroma factors may be treated by the devices 16 and systems as previously described to produce a de- alcoholised mixture of aroma and flavour factors 54.
  • This de-alcoholised mixture of aroma and flavour factors 54 may then be returned to the de-alcoholised beverage 51 produced by the distillation process.
  • the volume of material to be de- alcoholised is greatly reduced and physical and chemical factors (pH, salt concentration, etc. ) are more conducive to use of the devices.
  • the conversion of ethanol in absolute alcohol solutions, beer and white wine distillate to acetaldehyde by alcohol dehydrogenase was investigated.
  • the beer test samples were taken from a 440ml can of McEwans Export beer.
  • White wine is currently de-alcoholised by distillation (see previous discussion).
  • the resulting distillate is a solution of 20% ethanol also containing the major flavour and aromatic components of wine.
  • the test distillate samples were a gift from an industrial supplier.
  • Alcohol dehydrogenase activity was measured by the increased absorption at 340nm following the conversion of NAD to NADH by standard procedures (Bernofsky, C and Swan, M (1973) Anal. Bioche . 53_, 452). Samples of 2.5 mis were incubated with 100 units of yeast alcohol dehydrogenase for fifteen minutes at room temperature.
  • the present invention provides devices and methods for decreasing the alcohol content of wines and beers.
  • the present invention also gives 'alcohol-free' or 'low- alcohol' beverages produced using these devices and methods which have the flavour, texture and quality which the consumer has come to expect from the equivalents containing more alcohol.
