Biochemical Changes in Fatty Acids, Hydrocarbons and Sterols as well as Total Lipids of Albino Rats Ingested some Synthetic Colourants and Flavourants as Food Additives
The present study was carried out to investigate the effect of ingested synthetic food colourants or flavourants on total lipids content feces. The feces of rats ingested synthetic food colourants or flavourants has more lipids than that of control feces. In treated rat feces some fatty acids were disappeared (C19) or appeared (C14) while the other were increased (C15, C20, C18:2) or decreased (C6) when compared with the control feces. Most of unsaturated fatty acids (un SFA) might bind with the synthetic food colourants or flavourants and secreted in feces, but less consumed than saturated fatty acids (SFA) which, observed on hydrocarbon components, but sterols including cholesterol were more secreted by synthetic food additives treatments. Generally, the increase of total lipids and lipid fractions in feces such as unsaturated fatty acids (un SFA), total sterols (TS) especially cholesterol maybe due to their abilities to bind with food additives and form complex which secreted in feces.
