The important finding of the present study includes the amount
of TFAs found in both types of analysed products. Although low
TFA concentrations were observed in biscuits, in which the largest
value corresponded to 0.86% of total fatty acids, much higher values of these fatty acids were observed in salty snacks, including
7.94% in Italian snack and 5.53% in the ham and cheese puff pastry.
This discrepancy can be explained by the fact that, besides being
produced using different ingredients, salty snacks are sold without
any labelling or nutritional information, unlike biscuits. Moreover,
Brazilian industries have been encouraged by national and international government agencies to reduce the hydrogenated fats and TFA content in foods.
