Head: Noam Alkan, Ph.D.

The Department of Postharvest Storage of Fresh Produce includes 13 research laboratories working on development of postharvest technologies to retain quality and prevent losses of fruit, vegetables and ornamentals. Our main research goals are development of protocols and technologies for harvesting and marketing of fresh produce, study the molecular and biochemical mechanisms involved in regulation of ripening and senescence processes, develop safe technologies for decay control, and breeding of new varieties with improved postharvest storage capabilities. The research projects include evaluation and development of cooling technologies, control of humidity and gas atmosphere conditions, coatings and packaging materials, and antimicrobial compounds. The research is conducted on various fruit types, such as subtropical and deciduous fruit, vegetables, such as leafy, fruit and root vegetables, and ornamentals and cut flowers.
