Análise química e microbiológica do sururu (Mytella falcata) com e sem leite de coco

Abstract

The World Health Organization defines malnutrition as a variety of pathological conditions that arise as a result of deficiency of supply, transportation or use of nutrientes by the body s cells. Associated with energy and protein deficiency found in malnourished children there is a lack of vitamins and minerals. Currently, iron deficiency and vitamin A have been gaining importance as well as public health problem. Therefore, a balanced diet of macro and micronutrients such certainly decrease the rates of nutritional deficiencies. An alternative would be to include regional foods with nutritional value-added and low cost. One of these options would be the mussels (Mytella falcata) kind enough cultivated on the Brazilian coast and especially in Alagoas in the Estuarine Complex Mundaú-Manguaba (CEMM). On this basis it is proposed to examine the profile of micronutrients (vit. A, Fe and Zn) in mussels and their safety for consumption. For this, we evaluated the degree of contamination by heavy metals (As, Hg, Pb and Cd) from samples of fresh mussels, using the methodology of the AOAC, 2005, the hygienic and sanitary preparations of mussels, with and without milk coconut through microbiological parameters recommended by Ordinance 12/2001 of the Ministry of Health, according to AOAC methodology, 2005, APHA, 2004 and BAM / FDA, 2006 and the profile of micronutrients (vit. A, Fe and Zn) using methodology AOAC, 2005. The results indicated that the contamination levels for heavy metals were determined by the Division under the National Health Surveillance of Food (Decree 685/98) and the hygienic and sanitary preparations of mussels with and without coconut milk were considered satisfactory according to law. The concentrations of vit. A, Fe and Zn showed that the mussels, with and without coconut milk, have higher levels of iron than meat, besides being a good source of zinc, although their levels are lower than observed in the meat. Both preparations of mussels were not considered sources of vitamin A.
