TL;DR: In this paper, cyclopropenoids fatty acids from Sterculia striata seed oil were characterized by gas chromatography/mass spectrometry (GC/MS) and quantified by GC-FID after derivation to fatty acid methyl esters using a cold base-catalyzed procedure.

TL;DR: In this paper, the difference between the actual ECN 42 triacylglyceride content in vegetable oils, obtained by HPLC analysis, and the theoretical value calculated from the fatty acid composition was applied to detect the addition of seed oils with high contents of linoleic acid to olive oils commercialized in Brazil.

TL;DR: A method for extracting and quantifying benzo[a]pyrene was evaluated and improved for samples of green and roasted ground Arabica and Conillon (Coffea canephora) Brazilian coffees as discussed by the authors.

TL;DR: In this article, different methods to determine total fat (TF) and fatty acids (FA), including trans fatty acid (TFA), in diverse foodstuffs were evaluated, incorporating gravimetric methods and gas chromatography with flame ionization detector (GC/FID), in accordance with a modified AOAC 996.06 method.

TL;DR: In this article, the authors compared the contents of trans isomer fatty acids and saturated fatty acids in different cookie samples and provided Brazilian authorities with information to implement laws that require only to declare on the label the content of saturated fatty acid.
