Documented Uses

... Purified patulin /is included/ in an analytical reagent kit for use as a standard for mycotoxins.
Medication: Patulin was also used at one time as an antibiotic cream for topical application, but was found to cause dermal irritation. /Former/
Patulin is a mycotoxin produced by a variety of molds, particularly Aspergillus and Penicillium. Although patulin can occur in many molding fruits, grains and other foods, the major source of patulin contamination is in apples with brown rot, and in apple cider or apple juice. Patulin is also an antibiotic. (L1942, L1943)
Food Contaminant -> MYCOTOXIN -> JECFA Functional Classes
