Sao Paulo Med. J.




Abstract The objective of this study was to evaluate the nutritional, sensorial and microbiological characteristics of pizzas with the inclusion of dehydrated mix of salmon and tilapia in the dough. Tilapia and salmon carcasses were cooked, pressed, ground, dehydrated and crushed, and a mixture of salmon (20%) and tilapia (80%) was made. This mix was included in the pizza dough at different levels (0%, 5%, 10%, 15% and 20%) and afterwards the toppings were added.In the dough composition, protein, ash and phosphorus levels rose linearly, while lipids, carbohydrates and caloric value of the dough samples decreased linearly as the mix levels increased. In pizzas, the moisture, lipids and carbohydrates contents were not different. Protein and ash contents presented a linear behavior. The inclusion of the mix was effective in reducing the saturated fatty acids and raising the content of polyunsaturated fatty acids. There was no difference between the pizzas for the sensorial attributes analysed. Therefore, the inclusion of up to 20% of dehydrated mix of tilapia and salmon added protein, minerals, and polyunsaturated fatty acids and maintained the acceptance of the pizza dough samples, which makes possible the preparation of a food product with health claims and good sensorial quality.
