| Abstract: | Proximate analyses and mineral composition of dried salted roes of hake (Merluccius merluccius) and ling (Molva molva) were determined. Both roes contained a significant amount of protein (39.1 and 43.6%, respectively) and lipid (14.13 and 14.80, respectively) because of their physiological role as reserves. Because this product is a typical food of one particular area, no specific data have been found in the literature about proximate and mineral compositions. Only trace elements (Fe, Cu and Zn) and macronutrients (crude protein and carbohydrates) varied with the type of roe. The most important minerals were Fe, Zn, K and Na. However, Na content was very high, and for this reason dried salted roe cannot be recommended for people who require dietetic control of blood pressure. |
