Vranová J., Ciesarová Z. (2009): Furan in food – a review. Czech J. Food Sci., 27: 1–10. Furan and its derivatives were identified in a small number of heat-treated foods back in the 60’s and 70’s. In May 2004, US Food and Drug Administration published a report on the occurrence of parent furan in a number of thermally treated foods. Since furan has been classified as “possibly carcinogenic to ...

Furan is a food processing contaminant which is formed as part of the coffee volatile aroma components generated during roasting. Furan is classified as a “possible human carcinogen” and recent risk evaluations have indicated that the exposure to furan in the diet is a human health concern. It has been reported that roasted coffee contains the highest furan levels when compared to other foods. ...

We have previously reported furan-maleimide Diels-Alder chemistry as a new methodology to couple maleimide-modified antibodies on furan-functionalized polymeric carriers in the preparation of immuno-nanoparticles for targeted drug delivery. In this report, we focus on the characterization, self-assembly behavior and drug encapsulation of two types of furan-functionalized co-polymers: poly(2-met...

the resistance of antimicrobials has become a global hazard with the irrational use of antibiotics. infection of drug-resistance bacteria seriously threatens human health. currently there is an urgent need for the development of novel antimicrobial agents with new mechanisms and lower levels of toxicity. in this paper, a series of (s,z)-4-methyl-2-(4-oxo-5-((5-substitutedphenylfuran-2-yl) methy...

Diels-Alder chemistry has been used for the thermoreversible cross-linking of furan-functionalized ethylene/propylene (EPM) and ethylene/vinyl acetate (EVM) rubbers. Both furan-functionalized elastomers were successfully cross-linked with bismaleimide to yield products with a similar cross-link density. NMR relaxometry and SAXS measurements both show that the apolar EPM-g-furan precursor contai...

OBJECTIVE Furan (C4H4O) is a heat-induced food contaminant that is utilized as an industrial chemical agent. Lycopene is a natural substance that is produced by plants and tomatoes. We aimed to evaluate the toxicity of furan on testes and the protective effect of lycopene in diabetic rats. MATERIAL AND METHODS Male Wistar albino rats were divided into five groups: Group 1 (control group) rece...

Furan, which occurs in a wide variety of heat-treated foods, is a potent hepatotoxicant and liver carcinogen in rodents. In a 2-year bioassay, furan caused hepatocellular adenomas and carcinomas in mice and rats but also high incidences of bile duct tumors in rats. Furan is bioactivated by cytochrome P450 enzymes to cis-2-butene-1,4-dial, an α,β-unsaturated dialdehyde, which readily reacts with...

Furan is a food processing contaminant classified as possibly carcinogenic to humans. As the occurrence of furan has been reported in a variety of foods processed in sealed containers, the objective of this work was to investigate if the contaminant can be found in home-cooked foods prepared in a pressure cooker. For that, several foods including beans, soy beans, whole rice, beef, pork, potato...

The insecticidal activity of five alkylfurans against the generalist insect herbivore beet armyworm, Spodoptera exigua, was examined. Two naturally occurring compounds, the avocadofurans 2-(pentadecyl)furan (1) and 2-(heptadecyl)furan (2), previously isolated from specialized avocado idioblast oil cells, and three homologues, 2-(tetradecyl)furan (3), 2-(hexadecyl)furan (4), and 2-(octadecyl)fur...

The occurrence of furan in some food products has already been known for a few decades, and it has been reconfirmed in more recent investigations that furan is present in a variety of foodstuffs. This list of products includes roasted coffee, which has been shown to generate furan as a result of the heat treatment at roasting which is applied to achieve the desired aroma and flavour profile of ...
