The Center was founded in 1978 by Adel Kader with the goal of organizing and coordinating knowledge transfer regarding reduction of postharvest losses and improving the the quality and marketability of fresh horticultural products. The research findings disseminated during this era by Kader and a cadre of colleagues is the cornerstone and foundation for our current year-round supply and global sourcing of quality fresh and minimally-processed produce and cut flowers.

Our mission today is to remain a leading source of information on quality, safety and marketability of fresh produce and to sustain the viability of the Center for the next generation of scientists and practitioners.  Our immediate goal is to broaden the level of involvement among our basic, applied and extension faculty and use the PTC platform to distill, translate, and disseminate emerging technology advancements to a broader industry and affiliated stakeholder audience.
