Phytochemical characterization and bioactive properties of strawberries treated...
Barkaoui, Salma; Madureira, Joana; Dias, Maria Inês; Barros, Lillian; Ferreira, Isabel C.F.R.; Margaça, Fernanda M. A.; Boudhrioua, NourhèneStrawberry is one of the most consumed berries worldwide and the compounds on its extracts present numerous health benefits, including antioxidant potential. In this work, the effects of processing strawberries by gamma radiation at 2 kGy and 7 days storage at 4 °C were evaluated regarding their phenolic profile and bioactive properties. From the HPLC–DAD-ESI/MS analysis, pelargonidin-3-O-glucoside was the main...
Effects of electron beam radiation on the phenolic composition and bioactive pr...
Madureira, Joana; Gonçalves, Inês; Cardoso, Jéssica; Dias, Maria Inês; Santos, Pedro M. P.; Margaça, Fernanda M. A.; Santos-Buelga, CelestinoOlive pomace is an agro-industrial waste product generated from the olive oil industry and constituted by bioactive compounds with potential applications in several industrial sectors. The purpose of this work was to evaluate the effects of electron beam (e-beam) radiation on olive pomace, specifically on phenolic compounds (by HPLC-DAD-ESI/MS) and the bioactive properties (antioxidant, antiproliferative, and a...

Microbiota assessment of fresh-cut apples packaged in two different films
Madureira, Joana; Gonçalves, Sara; Santos-Buelga, Celestino; Margaça, Fernanda M. A.; Ferreira, Isabel C. F. R.; Barros, Lillian; Cabo Verde, SandraThe aim of this work was to assess the natural microbiota of packed fresh-cut apples during refrigerated storage. Two different films were tested for the package, a biodegradable (PLA) film and a conventional and commercial one (OPP). Two antioxidant additives were applied, a natural olive pomace extract and the commercial ascorbic acid used by the industries. The results revealed lower bacteria counts in sampl...
Effect of olive pomace extract application and packaging material on the preser...
Madureira, Joana; Melgar, Bruno; Delgado Alves, Vitor; Moldão, Margarida; Margaça, Fernanda M. A.; Santos-Buelga, Celestino; Barros, LillianThe efficiency of natural olive pomace extracts for enhancing the quality of fresh-cut appleswas compared with commercial ascorbic acid and two different packaging films (biodegradable polylactic acid (PLA) and oriented polypropylene (OPP)) were tested. The composition of atmosphere inside the packages, the physicochemical parameters (firmness, weight loss and color), the microbial load, total phenolic content ...
