The present disclosure relates, in part, to compositions and methods for the at least partial removal of histamine from a fermented liquid. In one aspect, composition of the present disclosure comprises a histamine binding domain conjugated to a solid support via a cross-linker. In certain embodiments, the histamine binding domain comprises an aptamer. In certain embodiments, the histamine binding domain comprises an anti-histamine antibody.

Provided is a method of treatment of an alcoholic beverage, particularly beer or wine, for removing ingredient(s) causing undesirable sulfury and/or fatty flavor(s), by contacting the beverage with a composition comprising a polymer-hydrogen peroxide complex, wherein the polymer is derived from at least one N-vinyl lactam monomer, and wherein the hydrogen peroxide is present in an amount from about 1% by weight to about 50% by weight of the complex. Provided further is a method of treatment of an alcoholic beverage to remove at least (a) at least one ingredient causing at least one undesirable sulfury and/or fatty flavor, and (b) at least one ingredient causing colloidal haze, comprising contacting the beverage with a composition described herein. Provided furthermore is an alcoholic beverage obtained by the method(s) of treatment described herein.

A method for treating a fluid is provided using a particulate material in the form of a deposited layer having an upstream side and a downstream side wherein a flow of the fluid is directed through the deposited layer from the upstream to the downstream side at a first temperature. The method includes reconditioning the deposited layer and then resuming treatment of the fluid, wherein reconditioning comprises heating the deposited layer to a second temperature; and cooling the deposited layer to a third temperature at an average cooling rate in the range of up to about 20 C./min.

Certain embodiments of the invention provide a method of preparing a modified distilled alcoholic spirit, comprising contacting a corresponding starting distilled alcoholic spirit with a base under conditions that cause at least one free carbonyl compound in the starting distilled alcoholic spirit to be reduced, to provide the modified distilled alcoholic spirit that has at an alcohol by volume (ABV) of at least 15%. Certain embodiments also provide a modified distilled alcoholic spirit prepared by the methods described herein.

An apparatus for stabilizing liquid includes first and second filters, intermediate storage that stores a regenerable stabilizing agent, an inlet line supplying unstabilized liquid and connected to both filters and to the intermediate storage, and a switchable interconnection configured for, immediately after regeneration and cleaning of the first or second filter, selectively causing the one of the first filter unit and the second filter unit to be upstream of an other of the first filter unit and the second filter unit. The first filter unit and the second filter unit are configured to run in different operational phases that are offset in time from one another.

An apparatus and method for the removal of unwanted taste components from beverages is described. The apparatus provides a method for contacting a oleophilic-absorbing surface and/or hydrophobic-absorbing surface of polymer media with a beverage before, during or after it is dispensed so that undesirable flavors are selectively removed from the beverage without removing desirable flavors improving the enjoyment of its consumption.

The invention relates to the use of a polymer obtained from the cross-linking reaction between chitosan or a derivative thereof, for example carboxymethyl chitosan, and phytic acid or a salt thereof, to prevent and/or to mitigate the phenomena of oxidation of a fermented beverage, preferably an alcoholic fermented beverage.

The alcoholic fermented beverage can be red, white or ros wine.

The polymer of the invention acts by removing the iron ion, which is the cause of oxidative phenomena.

A variety of potentially harmful substances can be removed from alcoholic and non-alcoholic beverages as well as condiments using a pack that includes a variety of ingredients within a liquid-permeable housing. The pack is immersed in a liquid that needs to be detoxified, with the ingredients binding to the potentially harmful compounds within the liquid, and after a desired period of time, the pack is separated from the liquid, thus removing from the potentially harmful compounds that are bound to the ingredients from the liquid. When combined within a single compartment of the housing, the ingredients display synergy in removing of many of the potentially harmful compounds. Additionally, the packs can be enhanced for removal of particular sets of compounds, such as environmental pollutants, illicit substances, mold and mycotoxins, food additives, and additional alcohol toxins.

A filter layer containing a fibrous matrix and an adsorbent embedded in the fibrous matrix for the targeted removal of substances that impair taste, in particular from wine, as well as a filter system with the filter layer, a use of the filter layer, a process for manufacturing the filter layer and a process for removing phenols from wine. The filter layer contains a fibrous matrix, preferably with cellulose fibres, and an adsorbent embedded in the matrix. The adsorbent has a weight percentage between 15% and 60%. The adsorbent contains cellulose ester particles, preferably cellulose acetate propionate particles, at least 80% of the particles having a diameter of less than 200 um. Alternatively or additionally, the adsorbent contains cellulose ester fibres, preferably cellulose acetate fibres, at least 80% of the fibres having a length of 0.5-5 mm, and a largest external diameter of 10 m to 200 m.
