Biography & Education


Dr, Eleni D. Pliakoni, is an Associate Professor in Urban Food Production and Postharvest Handling in the Department of Horticulture and Natural Resources at Kansas State University, located at the K-State Olathe campus. Dr Pliakoni has 60% teaching and 40% research appointment and joined Kansas State University April 2013. She is supporting and expanding the Urban Food Systems M.S. specialization in the Kansas City metro area by developing relationships with the urban food systems industries and by teaching and developing graduate courses related with the M.S. specialization and her area of expertise. The graduate courses she is teaching include urban agriculture, urban agriculture study tour, urban food systems, and professional development in urban food systems, farm to fork produce safety and postharvest physiology and technology.

She has more than 15 years of experience working with postharvest handling of fresh fruits and vegetables in Florida, Greece, Spain, and Texas. Her research program is focused on postharvest technology for local and urban food systems. She is studying the effects of various storage methods on shelf life, flavour, and nutritional quality of fresh produce.  Furthermore, she is involved in international work, by leading the efforts of a USAID grant to build capacity in postharvest management of horticultural crops in Tanzania with main goal to reduces postharvest losses and increase availability of nutritious food https://horticulture.ucdavis.edu/people/eleni-pliakoni. Finally, starting in 2019, she has established the first analytical lab in Kansas for cannabinoids analysis  offering two levels of cannabinoid testing: the "Basic" panel and an "Expanded" cannabinoid panel,  olathe.ksu.edu/hemp. The Basic panel covers THC, THCA, CBD, CBDA and CBN. The Expanded panel covers all five of the Basic panel cannabinoids as well as 11 additional cannabinoids: CBG, CBGA, CBDV, CBDVA, THCV, THCVA, Δ-8-THC, CBL, CBLA, CBC and CBCA.Testing services are available to individuals who are actively licensed through their state's Department of Agriculture. In addition to the services she is conducting research with Industrial Hemp looking on different postharvest handlings (packaging, drying) to maintain quality and extend shelf life.

Dr. Pliakoni and her lab are identifying preharvest factors that affect storage and postharvest handling techniques of fresh fruits and vegetables that could be applied by small-scale growers and in an urban environment. They are working to improve growing practices in terms of food safety and quality. This includes improving the marketable quality of produce, increasing its shelf life and increasing nutritional aspects that benefit human health.  Some of her work is focused on determining the effect of two production systems (high tunnel vs. open-field) on the postharvest losses and nutritional quality of tomato and spinach. Also, she is working on developing modified atmosphere packaging (MAP) technology that could be used by local farmers in order to reduce food losses. Additionally, she is examining the preharvest effects on postharvest quality of strawberries grown in high tunnels. She is also working on examining the impact of light on yield and nutritional quality of tomato and lettuce growing in high tunnels. Also, she is interested in best storage and packaging conditions for sweet potato slips as well as transportation conditions of grafted vegetable seedlings. Furthermore, she is working on improving shelf life, quality and safety of locally grown vegetables in Kansas. For more information, visit Postharvest Physiology Lab.
