Sabrina Moro et al.
Molecular nutrition & food research, 56(8), 1197-1211 (2012-05-30)
Furan is formed in a variety of heat-treated foods through thermal degradation of natural food constituents. Relatively high levels of furan contamination are found in ground roasted coffee, instant coffee, and processed baby foods. European exposure estimates suggest that mean
Thomas Wenzl et al.
Analytical and bioanalytical chemistry, 389(1), 119-137 (2007-08-04)
Heat-induced food contaminants have attracted attention of both the scientific community and the public in recent years. The presence of substances considered possibly or probably carcinogenic to humans has triggered an extensive debate on the healthiness of even staple foods.
Luca Chiari et al.
The Journal of chemical physics, 138(7), 074302-074302 (2013-03-01)
Cross section results from a joint experimental and theoretical investigation into positron scattering from 3-hydroxy-tetrahydrofuran (3H-THF) are presented. Total and positronium (Ps) formation cross sections have been measured from 1 to 190 eV using the positron beamline at the Australian
Joseph Salamoun et al.
Organic letters, 16(7), 2034-2037 (2014-03-20)
Two complementary approaches for the preparation of linked 5-membered heterocycles were developed. The Pd-catalyzed Suzuki-Miyaura cross-coupling with halogenated furan, thiophene, and selenophene led to higher overall yields, but C,H-bond activation was a more efficient strategy for the coupling at C(2)
María S Mariotti et al.
Food & function, 4(7), 1001-1015 (2013-04-10)
The presence of furan in a broad range of heat processed foods (0-6000 μg kg(-1)) has received considerable attention due to the fact that this heat induced contaminant is considered as a "possible carcinogenic compound to humans". Since a genotoxic
