Halochromic sensors for real-time monitoring of spoilage of packed seer fish

Development of halochromic thin film sensors for monitoring the degree of spoilage of packaged seer fish is described in this study. Three halochromic thin film sensors were prepared by combining a halochromic dye with starch/potato dextrose agar, polyvinyl alcohol, and cellulose acetate and characterized using Fourier-transform infrared spectroscopy. The halochromic sensors were tested for monitoring spoilage of packaged seer fish at ambient...
