Scientists at Indian Institute of Technology, Guwahati have developed a simple paper kit that can test freshness of milk and tell how well it has been pasteurized. The kit is sided with smart phone app to ensure that milk is consumed before it turns too sour. The team has prepared a kit by attaching probe discs onto a 2 cm square transparent cellulose acetate film. The probe is then covered with another cellulose acetate film. Colour reaction takes place when milk is injected through a tiny hole in the cover and a smart phone can be used to get the results. It takes just about 15 minutes to detect raw milk from pasteurized one.
