## Abstract

A method of removing a phenol contaminant from a beer or wine comprising contacting the beer or wine with a surface comprising a phenol contaminant effective removing amount of a poly(N-vinyl-2-pyrrolidone).

## Claims

### Claim 1

A method of removing a phenol contaminant from a beer or wine comprising contacting the beer or wine with a beverage container having a potably acceptable surface comprising a composite of a cross-linked polyvinylpyrrolidone (PVPP) and a matrix.

### Claim 2 (depends on 1)

The method according to claim 1 wherein the composite comprises about 1% to about 99% of cross-linked polyvinylpyrrolidone (PVPP) by weight of the total composite composition.

### Claim 3 (depends on 1)

The method according to claim 1 wherein the surface comprises a material selected from the group consisting of a metal, a metal alloy, a glass, aluminum, an aluminum alloy, a steel, a plastic, and a combination thereof.

### Claim 4 (depends on 3)

The method according to claim 3 wherein the aluminum is coated with the composite of cross-linked polyvinylpyrrolidone (PVPP) and a matrix.

### Claim 5 (depends on 3)

The method according to claim 3 wherein the glass is coated with the composite of cross-linked polyvinylpyrrolidone (PVPP) and a matrix.

### Claim 6 (depends on 5)

A method of preparing the composite of claim 5 comprising mixing the matrix and the PVPP (cross-linked polyvinylpyrrolidone) above the glass transition temperature of the matrix and/or the PVPP.

### Claim 7 (depends on 6)

The method according to claim 6 wherein the mixing is in a screw extruder.

### Claim 8 (depends on 6)

The method according to claim 6 wherein the process further comprises an injection molding or blow molding process.

### Claim 9 (depends on 3)

The method according to claim 3 wherein the surface is a monolayer or multilayer.

### Claim 10 (depends on 1)

The method according to claim 1 wherein the phenol contaminant is selected from the group consisting of a phenol monomer and a phenol polymer.

### Claim 11 (depends on 10)

The method according to claim 10 wherein the phenol polymer comprises from 2 to 10000 monomeric units.

### Claim 12 (depends on 1)

The method according to claim 1 wherein the matrix is selected from the group consisting of a base polymer, a glass, a plastic, a resin and a combination thereof.

### Claim 13 (depends on 12)

The method according to claim 12 wherein the base polymer is selected from the group consisting of poly(ethylene terephthalate) (PET), high density polyethylene, (HDPE), low density polyethylene (LDPE), polypropylene, polystyrene, polycarbonate, styrene-butadiene copolymers, poly(ethylene 2,6-naphthalene-2,6-dicarboxylate), and a combinations thereof.

### Claim 14 (depends on 12)

The method according to claim 12, wherein the resin is selected from the group consisting of epoxy, acrylic and its copolymer, nylon, polybutylene, ethylene-maleic acid copolymer, and polypropylene.

### Claim 15 (depends on 14)

The method according to claim 14 wherein the epoxy resin is epoxy resin comprising a bisphenol.
