Approximately 7.3 million tonnes of food is wasted annually in Australia. A substantial portion of this food is discarded due to having expired before being consumed. Measuring the ripeness of fruit and vegetables can assist with managing fresh produce to limit food wastage. Most current ripness sensing methods are expensive, time consuming or destructive. A gap exists in current methods for a low cost, non-destructive device capable of measuring ripeness. This project aimed to address this knowledge gap by constructing and testing a low-cost firmness based non-destructive ripeness measuring device. The device was constructed and tested against an judgement made by a human panel. Results showed a correlation between the human judgement and the judgement made by the machine. Further testing is required to determine if the method used correlates to current methods of testing for ripeness and whether factors such as fruit size, fruit shape, and temperature have an impact on the results achieved.
