The present disclosure belongs to the technical field of analytical chemistry, in particular to synthesis and application of a nanomaterial for removal of patulin (Pat). The present disclosure adopts 2-Oxin as a substitute template, AM as a functional monomer, and synthetic Fe.sub.3O4@SiO.sub.2@CS-GO magnetic nanoparticles as a carrier, for preparing a magnetic MIP specific for Pat adsorption by surface imprinting. The addition of Fe.sub.3O.sub.4 makes the finally prepared molecular imprinted adsorbent material magnetic, thereby facilitating separation of a material from a matrix, eliminating complicated operation steps such as filtration and centrifugation, and facilitating recovery of materials.

The present invention in its broadest aspect relates to a method for reducing glycoalkaloid content and turbidity of an aqueous phase comprising compounds selected from two or more of PA, PI, PPO, LipO, pectin, lipid, glycoalkaloid and phenolic compounds of which at least one compound is selected from PA, PT, LipO and PPO; a) providing an aqueous phase comprising compounds selected from two or more of PA, PI, PPO, LipO, pectin, lipid, glycoalkaloid and phenolic compounds of which at least one compound is selected from PA, PT, LipO and PPO; and b) performing one or more steps to reduce the concentration of solanine in the dry matter of the aqueous phase with at least 15 percent, such as at least 20%, such as at least 25% and to achieve an optical density at 620 nm of the remaining aqueous phase of less than 0.7; such as less than 0.5; such as less than 0.3; such as less than 0.2; such as less than 0.1; and thereby obtaining an aqueous phase having reduced glycoalkaloid content and turbidity compared to an untreated aqueous phase.

Packaging a fermented beverage in an aluminum-bearing or containing vessel includes controlling a concentration of sulfur dioxide within the fermented beverage. The concentration of the sulfur dioxide is decreased by subjecting the fermented beverage to a chemical process in batch or in-line and prior to filling the vessel or after filling the vessel.

One embodiment of a device used for Coffee Cupping in which coffee grounds, tea or other sediment to be extracted are mixed with a liquid in a vessel with a narrow section 24 between an upper chamber 20 and a lower chamber 26. After the sediment has settled in the lower chamber, a stopper 28 (attached to a rod 30, and a handle 32) is inserted into the narrow section 24 thereby sealing off the lower chamber 26 and allowing the now sediment-free liquid in the upper chamber 20 to be poured out using the pouring spout 22, into another vessel for tasting. Alternative embodiments are described and shown.

The present invention provides a method for preparing a plant derived beverage product or process intermediate, the method including the steps of: providing a crushed or liquefied extract of a plant material, exposing the extract to a size exclusion purification means involving membrane filtration (such as nanofiltration, ultrafiltration, reverse osmosis or cross flow filtration) to provide a beverage product or a process intermediate thereof, wherein the purification means is capable of at least partially separating an undesirable component, from a desirable component. The purification methods may be applied to plant materials to selectively remove various components, while leaving others. This allows for the preparation of custom plant extract beverages.
