Method and system for removing impurities from aliments
First Claim
1. A method for improving the quality of an aliment by removing therefrom an impurity selected from the group consisting of carbamates, sulfites, bioamines, and combinations thereof, comprising the steps of:
- (A) contacting an aliment containing an impurity selected from the group consisting of carbamates, sulfites, bioamines and combinations thereof, with a container formed of a membrane permeable to the impurity and its breakdown products and enclosing a reactant non-diffusible through the membrane and selected from the group consisting of;
(i) a binding agent,(ii) a neutralizing agent,(iii) an oxidizing agent,(iv) a transesterifying agent,(v) a hydrolyzing agent, and(vi) combinations thereof; and
(B) separating the container and the contents thereof from the aliment after a period of time sufficient for the reactant to react with the impurity.

Abstract
A method for improving the quality of an aliment, such as an alcoholic liquor, by removing impurities such as carbamates, sulfites and bioamines, includes contacting an aliment containing the impurity with a container formed of a membrane permeable to the impurity. The container encloses a non-diffusible reactant such as binding agents, neutralizing agents, oxidizing agents, transesterifying agents and hydrolyzing agents. The container and the contents are separated from the aliment after a period of time sufficient for the reactants to react with the impurity.
