A method for producing an ethanol solution includes obtaining, from a starting liquid, a liquid feed having less than by weight of constituents and having 3% to 25% by weight of ethanol, supplying the liquid feed to a feed stream inlet of a reverse osmosis separation system having a first pass, wherein (i) each pass has an reverse osmosis membrane filtration unit, each membrane filtration unit having an ethanol rejection percentage of between 50% to 99%, and (ii) each pass has the feed stream inlet for a feed stream, a permeate stream outlet for a permeate stream, and a retentate stream outlet for a retentate stream, operating the system to maintain pressure in one of the membrane filtration units in a range of 1,200 to 4,000 psi, and obtaining retentate that is enriched with ethanol, the retentate differs from the starting liquid by absence of the removed constituents.

The present invention refers to a filtering device for filtering a fluid containing dissolved solutions and optionally colloidal substances, including solvents and solutes, comprising a first filter unit (12) serving to remove substances in a first filtering step by way of a membrane filtration, said removed substances having a molecular weight above a defined limit value, a second filter unit (19), disposed downstream of the first filter unit (12), for the treatment of the permeate of the first filter unit (12), wherein the second filter unit (19) comprises a filter bed comprising at least one filter material of the group comprising graphene, modified graphene, graphite, activated carbon and a zeolite compound, and a third filter unit (20), disposed downstream of the second filter unit (19), for the treatment of the permeate of the second filter unit (19), wherein the third filter unit (20) comprises a porous membrane, through which the liquid to be filtered flows in a cross-flow. The present invention provides a device with the possibility of filtration with high working pressure, avoiding possible clogging inside the adsorbing material and easy regeneration and reactivation of the adsorbing material.

The present disclosure provides a juice filtration system to effectively reduce calorie and sugar contents, reduce bitterness, and improve the overall flavor of a juice. A method for making a fruit beverage utilizing the juice filtration system is also provided. The method includes multi-step filtrations of feed juice(s) followed by selective combination of the intermediate products, by-products, the feed juice(s), and/or other fruit source(s) to form the fruit beverage. A fruit beverage having a 100% identity to the original fruit source(s), reduced calorie and sugar content, reduced bitterness, enhanced vitamin nutrition, and improved flavor, free from external ingredients is provided.

The present invention provides a process for the production of a protein powder having an improved solubility and taste profile from brewer's spent grain. The process comprises nanofiltration at a specified applied pressure. The present invention also provides a protein powder produced from brewer's spent grain, a process for producing food or beverage products incorporating the protein powder, and food or beverage products comprising the protein powder.

A method for preparing a filtered beverage includes filtering a raw beverage using a cross-flow ultrafiltration device to produce a solids fraction and a liquid fraction; heating the solids fraction to a temperature of 60° C. or greater to produce a pasteurized solids fraction; microfiltering the liquid fraction through a microfilter having a size cut-off of 1 μm or smaller to produce a microfiltered liquid fraction; and combining the pasteurized solids fraction and the microfiltered liquid fraction to result in the filtered beverage.
