Abstract

Quality control of foods is important for both industrial and personal concerns. In the past decade, a variety of sensor techniques have been developed and various applications realized for the analysis of foods in both the liquid and gas phases. In this paper, we report a chemiluminescence (CL) sensor array based on nine catalytic nanomaterials for the discrimination of eight vinegars. CL response patterns can be obtained as 'fingerprints' for a given compound on the sensor array and then discriminated using linear discriminant analysis (LDA). The experiments demonstrate that the sensor array has excellent differentiability and reversibility.
