Smart Photodynamic Technology for Postharvest Decay Management (2026-2027)
Abstract
This project aims to develop an automated, packing-line compatible photodynamic treatment (PDT) system, coupled with spectral sensors to enable shelf-life prediction of fruits. In collaboration with ATEK Integrated Engineering and Mildura Fruit Company, the unit will be designed, fabricated and validated for citrus postharvest decontamination. The project will also assess citrus waste as a cost-effective photosensitiser, creating circular economy value. This will advance the technology from TRL 3 to TRL 5 to bring this green, residue-free, and resistance-free technology as an alternative to chemical fungicides closer to commercialisation.
