Accuracy studies of pH prediction using different pH biosensors when compared against a laboratory pH meter (a) [columns representing the predicted pH vs actual pH (primary axis) and lines representing % recovery vs actual pH in secondary axis], (b) % recovery values of pH prediction using different pH biosensors during storage and spoilage of raw milk (100% shows the accuracy close to pH meter); (c) spoilage prediction using AM-FD150 pH biosensor and pH meter showing the transition of milk spoilage from both analytical method.
