Specific Detection of Buckwheat Residues in Processed Foods by Polymerase Chain Reaction

Abstract

A specific and qualitative detection method for buckwheat in foods using the polymerase chain reaction (PCR) was developed. Trace amounts of buckwheat in commercial food products were qualitatively detected by this method. It should be reliable for detecting buckwheat residues in processed foods and practical for monitoring the labeling system for allergenic food materials.
