Evaluation of sardine cooking wastewaters as feed intake modulators for Europea...
Resende, Daniela; Velasco, Cristina; Pereira, Maria J.; Sá, Tiago; Rocha, Célia; Cunha, Luís M.; Lima, Rui C.; Brazinha, Carla; Pintado, ManuelaThere has been a tendency to replace marine ingredients in aquafeeds, namely fishmeal, with more sustainable vegetable protein sources. However, this replacement often reduces diet palatability, with a subsequent decrease in feed intake and growth and/or alteration of flesh quality. The goal of this work was to evaluate the effectiveness of aromatic mixtures extracted from sardine cooking wastewaters, a by-prod...
Functional characterisation and sensory evaluation of a novel symbiotic okara b...
Voss, Glenise B.; Monteiro, Maria João P.; Jauregi, Paula; Valente, Luísa M.P.; Pintado, Manuela E.This study aimed to produce four different beverages from okara (soybean by-product) previously hydrolyzed by Cynara cardunculus enzymes and fermented by probiotic bacteria or unfermented beverage. The probiotic viable cells, the isoflavones profile and organic acids were evaluated in the okara beverage. In addition, total phenolic content, antioxidant and ACE inhibitory activities were evaluated at storage tim...
Use of technological processing of seaweed and microalgae as strategy to improv...
Batista, Sónia; Pintado, Manuela; Marques, Alexandra; Abreu, Helena; Silva, Joana L; Jessen, Flemming; Valente, Luísa M.P.Algae are natural sources of nutrients, but the presence of anti-nutritional factors often compromises nutrient apparent digestibility coefficients (ADCs) in several fish species. In this study, physical-mechanical and enzymatic technological processing was applie to two seaweeds (Gracilaria gracilis and Ulva rigida) and three microalgae (Nannochloropsis oceanica, Chlorella vulgaris, and Tetraselmis sp.) in ord...
Fish energy budget under ocean warming and flame retardant exposure
Anacleto, Patrícia; Figueiredo, Cátia; Baptista, Miguel; Luísa Maulvault, Ana; Camacho, Carolina; Pousão-Ferreira, Pedro; Valente, Luísa M.P.Climate change and chemical contamination are global environmental threats of growing concern for the scientific community and regulatory authorities. Yet, the impacts and interactions of both stressors (particularly ocean warming and emerging chemical contaminants) on physiological responses of marine organisms remain unclear and still require further understanding. Within this context, the main goal of this s...
New approach for vitamin E extraction in rainbow trout flesh: Application in fi...
Araújo, Mariana; Alves, Rita C.; Pimentel, Filipa B.; Costa, Anabela S.G.; Fernandes, Telmo J.R.; Valente, Luísa M.P.; Rema, PauloA vitamin E extraction method for rainbow trout flesh was optimized, validated, and applied in fish fed commercial and Gracilaria vermiculophylla-supplemented diets. Five extraction methods were compared. Vitamers were analyzed by HPLC/DAD/fluorescence. A solid-liquid extraction with n-hexane, which showed the best performance, was optimized and validated. Among the eight vitamers, only α- and γ-tocopherol were...
Lipid content and fatty acid profile of Senegalese sole (Solea senegalensis Kau...
Fernandes, Telmo J. R.; Alves, Rita C.; Souza, Tiago; Silva, J. M. G.; Castro-Cunha, M.; Valente, Luísa M.P.; Oliveira, M. Beatriz P. P.A growth trial with Senegalese Sole (Solea senegalensis Kaup, 1858) juveniles fed with diets containing increasing replacement levels of fishmeal by mixtures of plant protein sources was conducted over 12 weeks. Total fat contents of muscle, liver, viscera, skin, fins and head tissues were determined, as well as fatty acid profiles of muscle and liver (GC-FID analysis). Liver was the preferential local for fat ...
