Abstract
A method for removing a selected contaminant from a liquid food product is disclosed. A special application of the method is for removing an antibiotic from milk. The method comprises the steps of contacting the milk with a matrix-antibody composition, wherein the antibody has a specific affinity for the selected contaminant, for a time and at a temperature sufficient for the contaminant to bind to the antibody to form a complex, and separating the complex from the food product. The matrix-antibody composition is regenerable by treating the complex with high ionic strength solution to release bound contaminants from the antibodies.
