Abstract

Conjugated linoleic acid (CLA) is recognised for its health benefits: anticancer, antiinflamatory and antiatherogenic effects have been reported. CLA enriched yoghurts were developed through homogenization at two levels (H1 and H2 with 40 and 80 mg CLA/100 g of yoghurt, respectively) with a view to creating functional foods. CLA modified the volatile profile in a positive way: higher levels of diacetyl and ethyl butanoate and lower values of 2-hexanone and 2-heptanone, ethanol and certain acids were recorded. Yoghurts presented similar microstructure, but H1 showed higher consistency and lower pseudoplastic behaviour; meanwhile H2 presented less syneresis. All products had high acceptability.
