Scientists develop AI-powered 'electronic nose' to sniff out meat freshness

Scientists have invented an artificial olfactory system that mimics the mammalian nose to assess the freshness of meat accurately. The 'electronic nose' comprises a 'barcode' that changes color over time in reaction to the gases produced by meat as it decays, and a barcode 'reader' in the form of a smartphone app powered by artificial intelligence.
