Proximate composition and caloric value of the mussel Perna perna, cultivated in Ubatuba, Sمo Paulo State, Brazil

Mussels of the genus Perna perna, cultivated in Ubatuba, São Paulo State, were analyzed for proximate composition and caloric value, month by month, during a year. From the nutritional point of view the proteins were outstanding (mean: 20.5% on a wet basis). The average contents of fats, ash and carbohydrates were, respectively, 3.24%, 2.24%, and 1.70%. The medium caloric value was 118 kcal 100 g−1. There were no marked variations, in the different months of the year for the proximate composition, except for the carbohydrates. This constant in the composition of the cultivated mussels indicates that there is a possibility to exploit mussels on a commercial basis.
