New Fruit Ripeness Sensor Developed
Supermarkets in the US lose in the region of 10% of fruits and vegetables per year as a result of spoilage. Now a new sensor designed and built by Chemistry professor Timothy Swager and his students could provide the solution. The sensors can detect even the smallest amounts of ethylene, the gas that promotes ripening. The idea is to attach the sensors to boxes of produce so that they can detect ripeness and report back on it via handhold scanners. This would give retailers a strong indication of when to put things on sale and, crucially, when to take them off.
