- Abstract
This study aimed to assess the nutritional quality and safety of a meal based on sururu, with or without coconut milk, and its micronutrients profile. The degree of contamination by heavy metals (As, Hg, Pb and Cd) was assessed in samples of sururu in natura, from the estuarine complex Mundaú-Manguaba (Maceio city, state of Alagoas, Brazil), according to the Association of Official Analytical Chemists (AOAC, 2005) method; Hygiene and sanitary conditions of the meal based on sururu, with or without coconut milk, by counting of thermotolerants coliforms, coagulase-positive Staphylococcus and Salmonella sp, according to the Brazilian Health Ministry, the Agriculture Ministry (2006), AOAC (2005) and the American Public Health Association (APHA, 2004). micronutrients profile was assessed according to AOAC (2005) methodology. Only As (0.63 mg) and Pb (0.34 mg), in a range allowed by the legislation, were found in our samples. No microbiological contamination was found. Micronutrient assessment showed that meals based on sururu had higher Fe content than bovine meat (sururu without coconut milk, 17.56 mg, and sururu with coconut milk, 13.8 mg), and that sururu is a good source of zinc (sururu without coconut milk, 0.97 mg, and sururu with coconut milk, 1.22 mg), has some vitamin A (sururu without coconut milk, 3.13 mg, and sururu with coconut milk, 4.73 mg). Results indicate that there was no chemical or microbiological contamination in these samples. Meals based on sururu are source of Fe and Zn and contain vitamin A, so they might be an alternat ive in the recovery of nutrit ional deficiencies.
