Prof. Rivka Barkai-Golan received her Ph.D in 1956 from the Hebrew University of Jerusalem. She has been a Senior Research Scientist in Postharvest Pathology and Mycology at the Volcani Center, Bet Dagan and a Professor of Postharvest Pathology at the Faculty of Agriculture of the Hebrew University of Jerusalem, where she has been honored a Distinguished Professor. Prof. Barkai-Golan has been a pioneer in the research on ionizing radiation as a means for prolongation of the postharvest life of fruits and vegetables; Chairman of the microbiological Group of the Institute of Technology and Storage of Agricultural Products (1979); Chairman of the Food Technology Committee of the United States Israel Binational Agricultural Research and Development (BARD) (1984); Chairman of the Steering Committee for Radiation Applications in Agriculture, and a Delegate of the Israeli Ministry of Agriculture for the International Conference on Food Irradiation in Geneva (1988) for the preparation of International Document on the Acceptance, Control and Trade in Irradiated Food. Prof. Barkai-Golan has been the recipient of search grants from BARD (1985, 1987) and from the CDR US-Israel Cooperative Development Research Fund (1988). She has published over 150 scientific papers as well as invited reviews and chapters. She wrote 4 books in the field of postharvest diseases. She was invited to present introductory and review lectures at International Congresses and Workshops, was the organizer and chairman of postharvest sessions in Israel, Wageningen Holland, Pretoria S.A., Caracas Venezuela, Kyoto Japan, Belgerate Italy, and presided over the Third Israeli-Italian Phytopathological Symposium, Tel Aviv (1994). Her current research interests are host-pathogen interactions, non-chemical means for postharvest disease suppression and factors involved in mycotoxin production in harvested fruits and vegetables.

(A.A. Kader, Department of Pomology, UC Davis, USA) Dr. Barkai-Golan effectively used her expertise and experience as a researcher and professor of postharvest pathology in writing a very informative reference book that will be very useful to teachers, students, researchers, extension workers, and others who are interested in reducing postharvest losses of produce. With more than 1000 cited references, this book presents a thorough review of the relevant literature on postharvest pathology of fruits and vegetables. Perishables Handling Quarterly No. 107
