Description
Summary:Passion fruit (Passiflora cincinnata Mast.) is a native fruit from the Caatinga, a typical ecoregion in northeastern Brazil, and it has potential for use by the food and pharmaceutical industries. In this study, we characterized the antimicrobial activity of P. cincinnata and its application in the production of coalho cheese, a traditional Brazilian product. Aqueous extract of P. cincinnata exhibited high inhibitory activity against Listeria spp. (n = 4, reference strains), Staphylococcus aureus (n = 3, reference strains), and multidrug-resistant Staph. aureus (n = 8), and low inhibitory activity against lactic acid bacteria (LAB, n = 3, reference strains). Based on these results, we produced coalho cheese using goat milk with and without (control) passion fruit. Cheeses were stored at 10°C for 14 d and populations of mesophilic aerobes, Staph. aureus, and presumptive LAB were monitored at d 1, 7 and 14. The passion fruit cheese had lower counts of mesophilic aerobes, Staph. aureus (after 7 and 14 d), and presumptive LAB (after 14 d) than the control cheese. Adding ground passion fruit contributed to a reduction of Staph. aureus counts in goat cheese, although these differences were not significant. These results indicated the inhibitory potential of passion fruit and its potential use for controlling microbial populations in a cheese model; further studies are needed to characterize the active molecules that are responsible for such activity.
