Pakistani researchers have developed an innovative low-cost sensor using Java Plum extracts to detect spoiled milk. Scientists from the University of Education Lahore and COMSATS University created this eco-friendly sensor, which changes color based on milk’s acidity levels, providing a real-time freshness check without any electronics.
The sensor is made by extracting anthocyanin from Java Plum, which gives the fruit its deep purple color. When infused into filter paper and stabilized with chitosan, it reacts to changes in milk’s pH, turning from purple to white as milk spoils. This method offers a more accurate and biodegradable alternative to traditional freshness indicators.

Published in Food Chemistry, the research highlights the potential of this sensor to revolutionize the dairy industry by reducing milk wastage. While boxed milk consumption is low in Pakistan, this innovation could have a global impact by saving millions of liters of milk each year.
The scientists are now seeking funding to commercialize the product, which could provide a sustainable and cost-effective solution for milk quality control. The entire research was conducted at COMSATS University, with all rights to the project held by IRCBM.
