It highlights that fungal spoilage causes about 10% of global food losses and serious mycotoxin risks, while current methods remain slow and costly. The team presents a GPCR-based yeast platform capturing characteristic fungal volatiles before visible mold emerges. Human-derived olfactory receptors couple with engineered yeast G-proteins, transmitting signals via the MAPK cascade to induce fluorescent Ypet expression. With a low-cost smartphone microplate reader using a camera spectrometer and analysis software, this system enables simple, on-site early warnings, safeguarding grain security and UN SDGs.
