Web1 de dic. de 2016 · Formation of trans fatty acids (TFA) occurs during frying/heating of fats/oil. • TFAs were estimated in 6 fats/oils before/after heating/frying at 180 °C and 220 °C. • Heating/frying led to formation and increase in TFA in all fat/oil samples. • Heating/frying also increased the saturated fatty acids and decreased cis-unsaturated … Web4 de jul. de 2024 · Unsaturated fatty acids may be converted to saturated fatty acids by the relatively simple hydrogenation reaction. Recall that the addition of hydrogen to an alkene (unsaturated) results in an alkane (saturated). A simple hydrogenation reaction is: (1) H 2 C = CH 2 + H 2 → CH 3 CH 3. alkene plus hydrogen yields an alkane.
