Ítem Acceso Abierto Antimicrobial and physicochemical characterization of whey protein concentrate edible films incorporated with liquid smoke.(Elsevier, 2016-10) Soazo, Marina del Valle; Pérez, Leonardo Martín; Piccirilli, Gisela Noemí; Delorenzi, Néstor Jorge; Verdini, Roxana AndreaÍtem Acceso Abierto Characterization of polyphenols compounds extracted from stressed apple peel and their interaction with β-lactoglobulin(Elsevier, 2023-11) Llopart, Emilce E.; Verdini, Roxana Andrea; Delorenzi, Néstor Jorge; Busti, Pablo AndrésThis paper proposes to apply a postharvest environmental stress to red apples, Malus domestica, variety Red Delicious in order to increase the polyphenols compounds (PP) content in their peels. The possibility of enhancing extractable PP provides a useful alternative for the use of discarded crops in the food industry. A great increase in PP was observed in response to light damage produced by the environmental stress applied in this work. Flavonols > anthocyanins > flavanols > dihydrochalcones > phenolic acids is the order in PP content. The interaction of the extracted PP from unstressed and stressed apple peels with beta-lactoglobulin (β-LG) was characterized. A PP/β-LG complex which was formed with one single binding site in the protein was determined. The interaction was spontaneous and enthalpy driven. PP extracted from unstressed samples had greater affinity for the protein than PP extracted from stressed samples, possibly due to the polar characteristic of anthocyanins. The results of this last study could provide a better understanding of the interaction between PP and β-LG to incorporate them into functional foods.Ítem Acceso Abierto Effect of different combinations of glycerol and/or trehalose on physical and structural properties of whey protein concentrate-based edible films(Elsevier, 2016-05) Pérez, Leonardo Martín; Piccirilli, Gisela Noemí; Delorenzi, Néstor Jorge; Verdini, Roxana AndreaÍtem Acceso Abierto Effect of freezing on physical properties of whey protein emulsion films(Elsevier, 2013-06) Soazo, Marina del Valle; Pérez, Leonardo Martín; Rubiolo, Amelia Catalina; Verdini, Roxana AndreaÍtem Acceso Abierto Effect of pH on the effectiveness of whey protein/glycerol edible films containing potassium sorbate to control non-O157 shiga toxin-producing Escherichia coli in ready-to-eat foods(Elsevier, 2014-03) Pérez, Leonardo Martín; Soazo, Marina del Valle; Balagué, Claudia Elizabeth; Rubiolo, Amelia Catalina; Verdini, Roxana AndreaÍtem Acceso Abierto Heat treatment of calcium alginate films obtained by ultrasonic atomizing: physicochemical characterization(Elsevier, 2015-10) Soazo, Marina del Valle; Báez, Germán David; Barboza, Andrea; Busti, Pablo Andrés; Rubiolo, Amelia Catalina; Verdini, Roxana Andrea; Delorenzi, Néstor JorgeÍtem Acceso Abierto Physicochemical characterization of a heat treated calcium alginate dry film prepared with chicken stock(Wiley, 2017-02-20) Báez, Germán David; Piccirilli, Gisela Noemí; Ballerini, Griselda A.; Frattini, Agustín; Busti, Pablo Andrés; Verdini, Roxana Andrea; Delorenzi, Néstor Jorge; The chicken stock used in this work was prepared by Chef Damian Delorenzi.Ítem Acceso Abierto Prefreezing application of whey protein-based edible coating to maintain quality attributes of strawberries(Wiley, 2015-03) Soazo, Marina del Valle; Pérez, Leonardo Martín; Rubiolo, Amelia Catalina; Verdini, Roxana Andrea
