3-Acetyl-2,5-dimethylfuran is a flavouring ingredien Flavouring ingredient

2,5-Dimethylfuran is a derivative of furan. It is a heterocyclic compound of the formula C6H8O. While it may be abbreviated DMF, it should not be confused with dimethylformamide. 2,5-Dimethylfuran is a maillard product. 2,5-Dimethylfuran has been identified as one of the components of cigar smoke with low cilatoxicity (ability to adversely affect the cilia in the respiratory tract that are responsible for removing foreign particles). Its blood concentration can be used as a biomarker for smoking. 2,5-Dimethylfuran, together with 2,5-hexanedione and 4,5-dihydroxy-2-hexanone, is one of the main metabolites of hexane in humans, which play a role in the mechanism for the neurotoxicity of hexane.Recent advances have increased its attractiveness as a biofuel.

Parasorbic acid

6-methyl-5,6-dihydro-2H-pyran-2-one

C6H8O2 (112.0524)

Parasorbic acid, also known as parasorbate, is a member of the class of compounds known as dihydropyranones. Dihydropyranones are compounds containing a hydrogenated pyran ring which bears a ketone, and contains one double bond. Parasorbic acid is soluble (in water) and an extremely weak acidic compound (based on its pKa). Parasorbic acid can be found in american cranberry and rowanberry, which makes parasorbic acid a potential biomarker for the consumption of these food products. Parasorbic acid is the cyclic lactone of sorbic acid. Thermal treatment or hydrolysis converts the lactone to sorbic acid .
