IIT researchers invention will allow your smartphone to check for milk purity
Led by professor Shiv Govind Singh from the Department of Electrical Engineering and associate professors Soumya Jana and Siva Rama Krishna Vanjari, the research work was recently published by the Food Analytical Methods journal.
The team first developed a detector system that incorporates the use of indicator paper to measure the acidity in milk. They then developed a prototype smartphone-compatible algorithm that can accurately detect the colour change. Using the phone camera, the colour change in the sensor strips after they are dipped in milk is captured and then this data is transformed into pH (acidity) ranges.
Using three machine-learning algorithms, the researchers compared their detection efficiencies in classifying the colour of the indicator strips. Upon testing various milk samples with varying combinations of contaminants, they found a near-perfect classification with an accuracy of 99.71 per cent.
There are no reports about when this will be available to the general public, but development is on the way.
