Pocket-Friendly Device to Detect Adulteration in Milk: Milk Adulteration Detection
Researchers at the Indian Institute of Technology (IIT) Madras have developed a pocket-friendly device that can detect adulteration in milk. The device can accurately determine whether the milk sample is adulterated with substances such as water, starch, glucose, and urea.
The device is small and easy to use, making it an ideal tool for milk testers, farmers, and households. It operates on the principle of optical spectroscopy, which involves shining a light on the milk sample and measuring the amount of light absorbed by the sample.
The device’s development was motivated by the increasing prevalence of milk adulteration in India, which poses a significant health risk to consumers. The researchers hope that the device will help combat this problem by making it easier to detect adulteration.
According to the researchers, the device has a sensitivity of 98.5% and a specificity of 99.2%, making it highly accurate in detecting adulteration. The device is also affordable, costing less than Rs. 1000, making it accessible to a wide range of users.
This innovation is an example of how technology can be used to address societal issues and improve the quality of life for individuals.
Why this News is Important:
Milk is a vital source of nutrition for people of all ages, and its purity is of paramount importance.
