Real-Time Detection of Packaged Seer Fish Spoilage Using Halochromic Optical Nose

Development of a biodegradable and recyclable halochromic biosensor for monitoring spoilage of packaged seer fish is described in this study. The biosensor was prepared completely from materials of natural origin. The sensor was characterized by X-ray diffraction pattern (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectrometry (EDS) and image processing by CIELab. The biosensor indicated spoilage of fish by exhibiting a...
