Descrição
Resumo:The content of trans fatty acids in most consumed foods in Brazil is unknown. This study assessed trans saturated, monounsaturated and polyunsaturated fatty acids in samples of fried potatoes, cookies and ice cream. The analysis included: potato chips and fried potatoes from two popular fast food restaurants, ice cream of two different trademarks and from two fast food restaurants, and cookies of different trademarks. The samples of potato chips and cookies were acquired in different supermarkets in the city of Rio de Janeiro, and distinct manufacture dates were chosen. Six samples of each product were analyzed through gaschromatography. The average trans fatty acids content in fried potatoes from fast food restaurants was 4.74g/100g; in ice cream the values varied from 0.041g to 1.41g; and in cookies the values varied from 2.81g to 5.60g. No trans fatty acids were found in potato chips. Cream crackers had the highest values of trans fatty acids and the lowest content of unsaturated fat. In some products, the content of trans fatty acids in 100g was higher than the daily total intake recommended in several countries.
