RipeSense Labels technology is an intelligent ripeness indicator developed to detect volatile aroma compounds associated with the ripening. The sensor label works by reacting to aromas released by pears as it ripens and changes colour upon detection of ripening aroma volatiles. The sensor is initially red and graduates to orange and finally yellow. Consumers can conveniently match the colour of the sensor label with their eating preferences, accurately choosing and consuming fruit according to their firmness/ripeness preferences.
