Abstract

The present application described a method of reducing methoxypyrazines (MPs) in grapes or grape products comprising: (a) contacting the grape or grape product with a protein that binds to MPs at a pH of about 3 to about 4 to form a protein-MP complex; and (b) removing the protein-MP complex from the grape or grape product. Also described is a method of removing MPs from samples comprising contacting the sample with a polyethersulfone membrane.
