Abstract:Fingerprints of two varieties of rice and their mixtures were investigated by a nonlinear chemical reaction system consisting of rice components, sodium bromate, manganese sulfate, sulfuric acid and acetone. The variety of rice was identified by the visual characteristic of fingerprint and system similarity pattern recognition, and the content of each variety of rice in the mixture was determined by the quantitative information of fingerprint. The results show that nonlinear chemical analysis may be used to exactly identify the variety of pure rice and to accurately determine the content of each variety of rice in the mixture, indicating the method is simple and convenient.

 

Key words: nonlinear chemical analysis; binary mixture; variety identification; content determination; rice
