Desarrollo de una galleta dulce adicionada con fuente de omega 3 como alimento funcional / Development of a cookie with added omega 3 fatty acids source as functional food

ABSTRACT

The present work aims at develop of a cookie with added omega 3. Three different commercial forms of omega 3 were evaluated as docosahexaenoic acid (DHA) and ecoisapentaenoic acid (EPA) (emulsion, powder and oil) at different omega 3 (ω3) omega 6 (ω6) ratios (15, 18, 110). A multistage factorial system was used to evaluate, in general, the rheology of the dough, along with the texture, moisture, color, and aw of the cookies after baking. During the storage, the concentration of ω3 is evaluated as linolenic acid, ω6 as linoleic acid. DHA, EPA and sensory attributes of the final product are also evaluated. Through the elaboration of the dough, it was encountered that the emulsion and oil commercial forms of ω3 best performed the rheological test, at the ratios of 18 and 110, while for the cookies elaboration the best combination is emulsion form at ratio of 110; which is stored under extreme conditions (40 ± 2°C y 75 ± 5% RH) for a 60 days period, presenting good acceptance from a semi-trained panel and a decrease in the concentration of ω3 fatty acids as DHA + EPA of approximately 6%.
