Indian Researchers have developed new sensor that can detect toxic chemicals in food

Shiv Nadar Institution of Eminence Delhi-NCR noted that the chemosensor, provides good sensing ability to formaldehyde or formalin which is a naturally occurring organic compound upto 0.3 micro Moles (µM).|According to the Food Safety and Standards of India (FSSAI) regulation 2011, formalin is not permitted for use in food. However, the chemical is used as a preservative for fish and meat and as a disinfectant for treating external parasites and fungi in aquaculture.|So a new cost-effective sensor that can discriminate the formaldehyde from other analogues spectroscopically in parts per million (ppm) in food samples like preserved meat, fish and honey was developed.| The sensor is able to  quantify other analogues in honey such as methyl glyoxal (MGO).
