Minerals and essential fatty acids of the exotic fruit Physalis peruviana L.

Physalis peruviana is an exotic fruit that belongs to the Solanaceae family and which has recently started to be produced in Brazil, mainly in the Southern region. Once there is few data regarding its chemical composition, this work presents the centesimal and mineral composition and the fatty acid profile of the lipidic fraction of Physalis peruviana. Concerning the centesimal composition, Physalis presented high contents of ashes and total lipids, 0.8 and 3.16 g. 100 g(-1), respectively. In its mineral composition, K, Mg, Ca and Fe were the main elements, and Fe is present in concentrations higher than those in the common sources such as beans. The lipidic fraction presented predominance of the linoleic acid (72,42%) in its composition.
