Distribution of some volatile nitrosamines in cooked bacon.
It is now well established that cured meat products such as bacon contain trace amounts of N-nitrosodimethylaminel and that on cooking, N-nitrosopyrrolidine is f ~ r m e d . ~ ~ The origin of the N-nitrosopyrrolidine is not conclusively established, but may be formed from proline by nitrosation and subsequent decarb~xylation.~ The present study is restricted to the determination of these two ni...
متن کاملVolatile components of Pimpinella tragium Vill. from Iran
Volatile components of three parts of Pimpinella tragium Vill. (Umbelliferae family) from Iran were investigated qualitatively and quantitatively for the first time. Essential oils were isolated by hydro-distillation from stems plus leaves, inflorescence and seeds of P. tragium individually. The plant materials were collected from Polour (Northeast of Tehran Province). The yields of the ...

متن کاملVolatile compounds in fresh, cooked fresh, dried and cooked dried Agaricus bisporus using ambient temperature vacuum distillation
Ambient temperature vacuum distillation in conjunction with headspacesolid phase microextraction (HS-SPME) was used to study the volatile compounds (VC) in Agaricus bisporus. Different extraction times 2, 3, 4 and 5 h were also tested against VC yield and 4 h was found to be the best extraction time with most of the compounds retrieved. No significant difference was found between the VC extract...
