Leonardo Betiol, Lilian Fachin [UNESP]; Evangelista, Rodrigo Rodrigues [UNESP]; Ribeiro Sanches, Marcio Augusto [UNESP]; Basso, Rodrigo CorreaMade available in DSpace on 2020-12-10T19:55:34Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-04-01; Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); CYTED; In this research, the sorption isotherms of seven brands of commercial dry-cured ham with different chemical composition were assessed simulating the conditions of storage at three temperatures. For this purpose, the dry-cured h...
Chitosan-based silver nanoparticles: a study of the antibacterial, antileishman...
Lima, Douglas dos Santos; Gullon, Beatriz; Cardelle-Cobas, Alejandra; Brito, Lucas M.; Rodrigues, Klinger A. F.; Quelemes, Patrick V.Silver nanoparticles have been studied as an alternative for treatment of microbial infections and leishmaniasis, without promoting induction of microbial or parasite resistance. In this study, chitosan-based silver nanoparticles were synthesized from silver nitrate (AgNO3), sodium borohydride as a reducing agent, and the biopolymer chitosan as a capping agent. The chitosan-based silver nanoparticles were chara...
Bioactive packaging using antioxidant extracts for the prevention of microbial ...
Moreira, Diana; Gullon, Beatriz; Gullon, Patricia; Gomes, Ana M.; Tavaria, FreniBioactive food packaging is an innovative approach for the prevention of the growth of food-spoilage microorganisms. Four active extracts from agroindustrial subproducts (Eucalyptus wood, almond shells, corn cobs and grape pomace) with demonstrated antioxidant activity have been investigated for bestowing antimicrobial activity to bioactive packaging. To carry out this evaluation, the antioxidant extracts were ...
Fermentation of bioactive solid lipid nanoparticles by human gut microflora
Madureira, Ana Raquel; Campos, Débora; Gullon, Beatriz; Marques, Cláudia; Rodríguez-Alcalá, Luís M.; Calhau, Conceição; Alonso, Jose LuisSolid lipid nanoparticles (SLNs) can be used for oral delivery of phenolic compounds in order to protect them from the harsh conditions of digestion and improve their bioavailability in the intestinal epithelium. Recently, the production and characterization of SLNs loaded with rosmarinic acid (RA) and herbal extracts was performed for future use as functional food ingredients. Diet components have been shown t...
Assessment of polyphenolic profile and antibacterial activity of pomegranate pe...
Gullon, Beatriz; Pintado, M. E.; Pérez-Alvarez, José A.; Viuda-Martos, ManuelaThe aim of this work were to determine the polyphenolic profile and the antibacterial properties of pomegranate peel flour (PPF), in view to its application in the food industry as potential antimicrobial “natural” agent. For thus, the antibacterial properties of PPF were tested against: Listeria monocytogenes, Listeria innocua, Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and Salmonella sp. ...
