Development and characterization of nutritious and sustainable canned fish meal...
Oliveira, Helena; Cristóvão, Maria; Nabais, Alexandre; Camacho, Carolina; Sapatinha, Maria; Pires, Carla; Lourenço, Helena M.; Fernandes, Maria H.Canning is an excellent solution to provide convenient, affordable, nutritious, and safe seafood with a long shelf life. However, many canned products use tuna, sardines, and Atlantic chub mackerel, species that raise sustainability concerns and whose overuse can put additional pressure on them. Hence, this study aimed to i) develop and assess a nutritious and sustainable canned meal prototype using the Atlanti...
Biofortified Diets Containing Algae and Selenised Yeast: Effects on Growth Perf...
Ferreira, Mariana; Ribeiro, Pedro C.; Ribeiro, Laura; Barata, Marisa; Domingues, Valentina F.; Sousa, Sara; Soares, Cristina; Marques, AlexandraEfforts have been made to find natural, highly nutritious alternatives to replace fish meal (FM) and fish oil (FO), which can simultaneously promote fish health and improve the nutritional quality of filets for human consumption. This study evaluated the impact of biofortified diets containing microalgae (as replacement for FM and FO), macroalgae (as natural source of iodine) and selenised yeast (organic source...
Trophic and reproductive biochemistry of a deep-sea gelatinous octopus, Opistho...
Rosa, Rui; Pimentel, Marta S.; Baptista, Miguel; Trübenbach, Katja; Calado, Ricardo; Nunes, Maria L.; Moreno, Ana; Pereira, JoãoThe present study provides a comprehensive analysis of the biochemical composition (proximate composition, amino acids and fatty acids in gonad, digestive gland and muscle) of the cirrate octopod, Opisthoteuthis calypso, collected off the coast of Portugal. Protein and energy contents of O. calypso were significantly lower (p\0.05) than those observed for coastal octopods, suggesting that the gelatinous musculat...
Quality Characteristics of High Pressure-Induced Hake ( Merluccius capensis ) P...
Cardoso, Carlos L.; Mendes, Rogério O.; Saraiva, Jorge A.; Vaz-Pires, Paulo R.; Nunes, Maria L.The effects of microbial transglutaminase (MTGase; 0.5%, w/w) and high hydrostatic pressure (HHP) on the quality of protein gels from unwashed mince of hake (Merluccius capensis) trimmings were studied. MTGase incorporation improved texture. Protein solubility was lower for those gels containing MTGase, as a result of myosin heavy chain cross-linking. HHP improved texture. Pressure level was the most important ...
Assessment of European cuttlefish (Sepia officinalis, L.) nutritional value and...
Sykes, António V.; Oliveira, Ana R.; Domingues, Pedro M.; Cardoso, Carlos M.; Andrade, José Pedro; Nunes, Maria L.Cephalopod landings and consumption have been increasing worldwide during the past decades. The main reason for this increasing demand is that cephalopods are a good protein and lipid source (Kreuzer, 1984; Sinanoglou & Miniadis-Meimaroglou, 1998, 2000; Zlatanos, Laskaridis, Feist, & Sagredos, 2006), thus a highly nutritious food that represents an alternative to over exploited fish resources. Nutritional value...
Total and organic mercury, selenium and alpha-tocopherol in some deep-water fis...
Afonso, Claudia; Lourenco, Helena M.; Pereira, Catia; Martins, Maria F.; Carvalho, Maria L.; Castro, Matilde; Nunes, Maria L.BACKGROUND: Mercury is a well-known toxic element present in seafood. Nevertheless some antioxidants, like selenium, as an integral component of the enzyme glutathione peroxidase, and alpha-tocopherol having a protective role against it, are present as well. The purpose of this study was to evaluate the levels of total mercury (Hg-T), organic mercury (Hg-Org), Se and alpha-tocopherol in some adult deep-water fi...
