Bromocresol green was used to monitor the production of TVBN and prediction of fish freshness by monitoring colour change during storage [10]. Myoglobin was used as indicator solution to monitor freshness of chicken broiler cuts [14]. An indicator sensor containing pH-sensitive dyes viz. bromothymol blue and methyl red was developed for monitoring freshness of intermediate-moisture dessert spoilage [8]. There are several researches where chemical indicator solutions have been used for fabricating indicator sensor, but very less work has been done on use of natural indicator solution for fabrication of indicator sensor to monitor the freshness and quality of food.
