Patulin
Patulin is found in pomes. Mycotoxin, found as a contaminant of foods, e.g. apple juice. 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 Mycotoxin, found as a contaminant of foods, e.g. apple juice. Sometimes detd. in apple juice D009676 - Noxae > D011042 - Poisons > D009183 - Mycotoxins D009676 - Noxae > D009153 - Mutagens Patulin (Terinin) is a mycotoxin produced by fungi including the Aspergillus, Penicillium, and Byssochlamys species, is suspected to be clastogenic, mutagenic, teratogenic and cytotoxic. Patulin induces autophagy-dependent apoptosis through lysosomal-mitochondrial axis, and causes DNA damage[1][2][3][4].

xi-3,6-Dihydro-4-methyl-2-(2-methyl-1-propenyl)-2H-pyran
Xi-3,6-dihydro-4-methyl-2-(2-methyl-1-propenyl)-2h-pyran is a member of the class of compounds known as pyrans. Pyrans are compounds containing a pyran ring, which is a six-member heterocyclic, non-aromatic ring with five carbon atoms, one oxygen atom and two ring double bonds. Xi-3,6-dihydro-4-methyl-2-(2-methyl-1-propenyl)-2h-pyran is slightly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Xi-3,6-dihydro-4-methyl-2-(2-methyl-1-propenyl)-2h-pyran can be found in alcoholic beverages, citrus, and fruits, which makes xi-3,6-dihydro-4-methyl-2-(2-methyl-1-propenyl)-2h-pyran a potential biomarker for the consumption of these food products. xi-3,6-Dihydro-4-methyl-2-(2-methyl-1-propenyl)-2H-pyran is found in alcoholic beverages. xi-3,6-Dihydro-4-methyl-2-(2-methyl-1-propenyl)-2H-pyran is present in grapefruit (Citrus paradisi), grapes and other fruit and in wine. xi-3,6-Dihydro-4-methyl-2-(2-methyl-1-propenyl)-2H-pyran is a flavouring ingredient.
