A team of scientists led by Nanyang Technological University (NTU), Singapore have invented an artificial olfactory system that mimics the mammalian nose and aims to assess the freshness of meat. The 'electric nose’ (e-nose) comprises a 'barcode’ that reacts with gases produced by decaying meat, and a 'barcode reader’ that uses AI to interpret the combination of colours on the barcode, researchers confirmed. By integrating it into a smartphone app, which the team claim can yield results in 30 seconds, the e-nose is portable and predicts meat freshness with 98.5 per cent accuracy.
