Abstract
The ingestion of saturated fatty acids can eventually bring health risks. Scientific evidence shows that the intake of trans isomer fatty acids creates a similar effect as the intake of saturated fatty acids. Brazilian laws demand only to declare on the label the content of saturated fatty acids. Several products are made by using hydrogenated vegetable fat, which is rich in trans isomers fatty acids, for example cookies, which are generally eaten by children and adolescents. The objective of this work was to compare the contents of saturated fatty acids and trans isomer fatty acids in different cookie samples and supply Brazilian authorities with information to implement laws. Twenty six samples were analyzed in six different brands. The four types of cookies tested were: wafers, salty cookies, cream filled and several sweet ones. The composition of fatty acids from the fat extracted of the cookies (Soxhlet) was determinated by gas chromatography. The contents of saturated and trans isomer fatty acids were similar in most samples, which showed a considerable percentage of the total lipids content. The results obtained will bring subsidies to reformulate the Brazilian laws, which will then demand that the content of trans isomer fatty acids...
