Abstract:
This chapter provides an overview of Penicillium expansum, the cause of the destructive blue mold rot of pome and stone fruits. It is a major concern for human health, because of the production of patulin during pathogenesis. Human exposure is primarily via consumption of infected apple juices and other apple-based products. Patulin occurrence has been reported in juices of other fruits, such as pears, grapes, cherries, apricots and oranges. The factors affecting P. expansum growth and patulin formation include fungal strain, host fruit cultivar, and storage conditions, especially the storage atmosphere. The chapter discusses the worldwide occurrence of patulin in fruit products. It also explains patulin contamination in infant apple products, and comparisons between its levels in-organic fruits versus conventional ones, industrial versus hand-made products, and cloudy versus clear apple juices. Penicillium mycotoxins other than patulin, including ochratoxin A, citrinin, penicillic acid, cyclopiazonic acid, and penitrem, as well as the co-occurrence of different mycotoxins, are also discussed. © 2008 Elsevier Inc.
