In a method for purifying highly pure isopropyl alcohol used in a semiconductor cleaning process, diacetone alcohol present in isopropyl alcohol is removed by an adsorption process, and diacetone alcohol, triisopropyl borate, and metal impurities are removed by a distillation process. The purified isopropyl alcohol may have a purity of has the moisture of 10 ppm or less, the triisopropyl boron compound of 50 ppt or less, and each metal of the metal impurities of 20 ppt or less.

The process of improving the flavour and aroma of liquor is an invention intended to mellow liquor flavours and aromas—like those of matured ones—and eliminate undesirable odours resulting from poor manufacturing process. The crux of the invention lies in a material which has unique properties and steps taken which include mixture preparation, selective optimisation of particles in liquor, separation of undesirable particles and arrangement of particles in liquor by relying on flow velocity, temperature, and electromagnetic field in controlling collision of particles in liquor. The output is liquor with rather unaltered physical appearance, ester and alcohol content, not causing irritated throat, burning stomach or nausea which results from uneven alcohol content throughout liquor's body. Besides, this process overcomes limitations of existing liquor treatment techniques; it does not bring more heavy metal residues to the output liquor or cause particles in liquor to become more volatile.

The present disclosure relates to a filter designed to purify alcohol, particularly spirits, and more specifically to a reusable multi stage spirit filter. The filter unit is adapted to connect with two fluid containers, the filter adapted receive commercial filter cartridges of the be a refillable filter. Typical filter materials being selected from activated charcoal or carbon, or an ion exchange resin. The reusable filter that can be repeatedly used to clean or polish spirits to remove the impurities thereby improving the taste of spirits.

The present disclosure relates to a compound, in particular it relates to a polymer that may be used in the field of protein removal from aqueous solutions, in particular from wines. Furthermore, the present disclosure also relates to a method of production of said compound and to uses thereof.

A device and a method for stabilizing wine or other vegetable beverages by removal, in whole or in part, of agents responsible for instability, including proteins and metals, are provided. The device has a tubular container filled internally at least partly with particles of support material covered with a layer of a mesoporous nanostructured adsorbent material comprising titanium oxide, adapted to absorb proteins and metals.

Provided is a method for manufacturing a long-life brewed alcoholic beverage by a filtration process with the use of a porous membrane involving a washing step, whereby a high tolerance (chemical tolerance) to a washing solution (a chemical solution) and a good filtration performance are achieved. A method for ma manufacturing a second brewed alcoholic beverage which includes: a filtration step for passing a first brewed alcoholic beverage, which contains a yeast and a high-molecular substance or sediment component produced through fermentation by the yeast, through a porous membrane, which is formed of a resin having a three-dimensional network structure, to thereby separate the second brewed alcoholic beverage from the yeast; and a washing step for passing a washing solution through the porous membrane or immersing the porous membrane in the washing solution to thereby wash the inside of the porous membrane.

Beverage filtration device including a lid body having an internal housing configured to hold an ion exchange resin-filed cartridge therein having a connection end and a top end having an opening therein, and, stem body having a cap region, collar, beverage conduit and stem air tube. The cap region couples to the connection end of the lid body to form a liquid-tight seal there-between. A collar wall first portion fits inside a beverage mouth container and a second portion located outside of the mouth. The beverage conduit spans the collar, a first conduit opening open to the coupling between the cap region the connection end and a second conduit open to a container interior. The stem body air tube extends through the collar, a proximal opening of the stem body air tube opens to an air vent hole located in the second portion of the collar wall, and, a distil opening of the stem body air tube opens to the container interior.

A device including a lid body including a connection end, a top end having an opening therein, a pouring spout body encompassing the opening, and, a stem body including an internal housing configured to hold an ion exchange resin-filed cartridge therein, a cap region, collar, a beverage conduit, and a stem body air tube. The cap region configured to couple to the connection end of the lid body to thereby form a first liquid-tight seal coupling between the connection end of the lid body and a top end of the ion exchange resin-filed cartridge, and, form a second a liquid-tight seal coupling between a base region of the internal housing and a bottom end of the ion exchange resin-filed cartridge. First and second collar wall portions sized to fit inside a mouth of a beverage container and to be located outside of the mouth. The beverage conduit spans the collar with a first and second openings to the base region and an interior of the beverage container. The stem body air tube extends through the collar with proximal and distal openings to an air vent hole located in the second portion of the collar wall and to the interior of the beverage container.

Treating a non-wine alcoholic beverage including: exposing the non-wine alcoholic beverage to an ion exchange matrix. The ion exchange matrix includes a mixture of cation exchange media and anion exchange media that includes: (1) cation exchange media that are in hydrogen form, (2) cation exchange media that are in mineral form comprising potassium mineral form, (3) anion exchange media that are in hydroxide form, and (4) anion exchange media that are in chloride mineral form. The exposing results in: binding ions of the mixture to one or more cationic or anionic constituents present in the pretreated beverage, reducing concentrations of the one or more cationic or anionic constituents in the beverage and maintaining a conductivity value of the treated beverage equal to or greater than the pretreated beverage's conductivity value. An apparatus for treating a non-wine alcoholic beverage and a treated non-wine alcoholic beverage prepared by a process are also disclosed.
