Sometimes detd. in apple juice Patulin is a mycotoxin produced by a variety of molds, particularly Aspergillus and Penicillium. It is commonly found in rotting apples, and the amount of patulin in apple products is generally viewed as a measure of the quality of the apples used in production. It is not a particularly potent toxin, but a number of studies have shown that it is genotoxic, which has led to some theories that it may be a carcinogen, though animal studies have remained inconclusive. Patulin is also an antibiotic. Several countries have instituted patulin restrictions in apple products. The World Health Organization recommends a maximum concentration of 50 µg/L in apple juice. 2,4-Dihydroxy-2H-pyran-&alpha;-acetic acid, 3, 4-lactone 2,4-Dihydroxy-2H-pyran-alpha -acetic acid, 3, 4-lactone 2H-Pyran-&alpha;)-acetic acid, 2, 4-dihydroxy-,3,4-lactone 2H-Pyran-&alpha;)-acetic acid, 2,4-dihydroxy-, 3,4-lactone 2H-Pyran-alpha )-acetic acid, 2, 4-dihydroxy-,3,4-lactone 2H-Pyran-alpha )-acetic acid, 2,4-dihydroxy-, 3,4-lactone 4-Hydroxy-4,6-dihydrofuro[4,5-c]pyran-2-one 4-Hydroxy-4H-furo(3,2-C)pyran-2(6H)-one 4-Hydroxy-4H-furo(3,3-c)pyran-2(6H)-one 4-Hydroxy-4H-furo[3,2-c]pyran-2(6H)-one 4-Hydroxy-4H-furo[3,2-c]pyran-2(6H)-one, 9CI, 8CI 4,6-Dihydro-4-hydroxy-2H-furo(3,2-c)pyran-2-one 4H-Furo(3,2-c)pyran-2(6H)-one, 4-hydroxy- 4H-Furo(3,3-c)pyran-2(6H)-one, 4-hydroxy- 4H-Furo[3,2-c]pyran-2(6H)-one, 4-hydroxy- Antibiotic Sch 351633 Antibiotic YS 1649 Clairformin Clavacin Clavatin Clavicin Claviform Claviformin Clavitin Expansin Expansine Expansion Flavicin Gigantic acid?
