Non Technical Summary
Angelos Deltsidis, Postharvest Extension Specialist located at the Tifton Campus of the Horticulture Department at the University of Georgia, along with graduate and undergraduate students and county extension agents, will be evaluating novel and existing postharvest technologies to reduce quality losses of fresh fruits and vegetables that are produced and/or traded in the State of Georgia as well as in neighboring states. The outcomes of this research will be communicated to the stakeholders via workshops, meetings and conferences as well as using new technologies.

Goals / Objectives
Build a locally-focused yet nationally renowned postharvest program at the Tifton Campus that will act as a hub to transfer knowledge between applied science and the strong Georgia Ag sector. Collaborate with colleagues from UGA and other universities nationally and internationally in order to foster interdisciplinary collaborations to produce scientifically based results that will be in turn disseminated to the State of Georgia produce industries.
Project Methods
Set up targeted experiments that respond to the needs of the local produce industries in collaboration with colleagues from the Dept. of Horticulture, UGA Extension agents and universities from the US and abroad.Measure produce quality indicators at harvest and during the postharvest period - firmness, soluble solids, pH and titratable acidity, as well as quality indicator compounds such as color and/or phenolics.Evaluate the effect of produce quality at harvest on the postharvest shelf life of fresh produce.Refine and retrofit existing postharvest systems in several local industries to improve their efficiencies and reduce overall postharvest losses.Prepare extension materials (blog posts, regional/industry workshop and conference talks) throughout the length of the project, and prepare journal and extension publications.

Outputs
Target Audience:The target audience of this project is a diverse community of stakeholders located in the state of Georgia as well asregionally with a common interest in the production and storage of fruits and vegetables. This includes small- and large-scale produce growers, packers, shippers, and marketers as well as warehouse postharvest managers, and industry practitioners.Furthermore, extension educators, consumers and in general members of the produce industry are part of our target audience. Last but not least, we are aiming at working with academics and students (undergraduate and graduate) that are interested in the research topics covered under this project. Specifically during the period reported the following extension presentations were given: Deltsidis, A. 2019. Fresh-cut Product Biology. Fresh-cut Products.

Changes/Problems:COVID 19 limited our capacity to perform research effectively due to restrictions in field work and lab usage. It also haltedthe student recruitment that was taking place in early 2020. What opportunities for training and professional development has the project provided?Until the end of this reporting period, apart from Dr. Deltsidis, a full time horticulture scientist and a part time undergraduate student are performing postharvest related research. How have the results been disseminated to communities of interest?On the extension front, a number of in person and virtual presentation connected Dr. Deltsidis with the stakeholders in the state of Georgia. He presented in 2 Georgia extension events and organized and presented a webinar.Additionally, he was invited to participateand present a number of lectures in 2 UC Davis organized workshops.Last, a number of in person visits and consultations were provided to local farmers. What do you plan to do during the next reporting period to accomplish the goals?We have submitted a number of grant applications for funding to conduct research in fresh fruits and vegetables many of which have been already funded while others are pending. Dr. Deltsidis is recruiting agraduate studentto fulfill the research needs of the lab. Also, a number of extension activities both in person and online have already been scheduled for the next reporting period.

Impacts
What was accomplished under these goals? The newly established postharvest program at UGA, forged collaborations with other members of the same institution as well as with colleagues from other U.S. institutions. As a results, a number of proposals for funding have been submitted and are in preparation for the year to come.
