After the publication of high levels of acrylamide (AA) in food, many research activities started all over the world in order to determine the occurrence and the concentration of this substance in various types of food. As no validated methods were a

Toxic equivalency factor (TEF) has been proposed to estimate the risk of polychlorinated biphenyl (PCB) congeners. However, ortho chlorine substitution in the two phenyl rings gives each PCB its own pattern of toxicity which is different from the mec

During the preparation of cooked foods acrylamide is formed from asparagine and reducing sugars at high temperatures. By-products of oil, starch and sugar production, which may be found in animal feed, partially result from processing steps using hea

Die Reaktionen von drei verschieden substituierten Chinonen (5–7) mit verschiedenen Dienen (2, 8–10) geben hauptsachlich „Ortho”-Addukte. Jedoch werden in mehreren Fallen auch „Meta”-Addukte isoliert. Die Ergebnisse werden auf der Basis v

Die Methyl-Abspaltung aus Piperididen des Typs CH3(CHCH)nCONC5H10 verlaft bei n = 1 bis 3 nicht uber einem Ringverengungsprozes, wie er fruher fur n = 0 bewiesen wurde. Die Fragmentierung kann uber einen cyclischen Ubergangszustand formuliert werden,

Durch die Untersuchung 2H-markierter Verbindungen wird belegt, das im Falle von Crotonsaurepiperidid nur die Wasserstoffe der Methylgruppe an der CH3·-Abspaltung teilnehmen. By the investigation of 2H labelled compounds, it has been established that
