Ahmedabad : Concerned about the quality of your daily food intake? A new rapid testing kit (RTK) developed by researchers at the National Forensic Sciences University (NFSU) enables quick detection of harmful additives and contaminants through strip and reagent based analysis within two to five minutes. These kits, designed for household application, are available at prices ranging from Rs 200 to Rs 500, according to officials.

Jayrajsinh Sarvaiya, associate professor at the School of Engineering and Technology at NFSU, said that while there are several kits available in the market, the development of RTK, which started about two years ago, was aimed at making a reliable kit applicable for a market like India. "Our focus was on segments such as milk and spices. The team has got a patent for liposomebased technique for one of the kits,” said Sarvaiya. “For example, urea is added to milk to improve the solids content and hydrogen peroxide to improve raw milk quality. While it may also occur in normal milk, its quantity is within permissible limits. Similarly, poorly-handled spices have aflatoxin B1 (AFB1) whereas some spices — especially turmeric and chilli powder – have addition of prohibited food dyes,” said Sarvaiya. 

The kit can be used both by industry and citizens’ 

The kits are designed to catch these frequently observed impurities. Similarly, if the food is claimed to be organic, it can be tested for urea concentrate,” Jayrajsinh Sarvaiya, associate 

professor at the School of Engineering and Technology at NFSU. Prof S O Junare, the campus director of NFSU Gandhinagar, said that the testing kits are regularly exhibited at food festivals and science fairs organized in Gujarat by the university. “It is affordable and easy to use. In the past few months, we have produced hundreds of such kits for various calibrations that can be used both by the industry and common citizens,” he said. “The kits come with a manual that provides the user guidance on how to use it. For example, in the milk testing kit, the user has to put four drops at the given points on the strip. If the strip changes colour — grey for starch, yellow for urea, orange for hydrogen peroxide — one can ascertain its presence,” said Sarvaiya. City-based physicians said that prolonged consumption of adulterated food items leads to health complications such as gastrointestinal issues, immunotoxicity and neurotoxicity among others.
