Production and characterization of protein-rich extracts from the red macroalga...
Mateus, Marília; Mão de Ferro, Rita; Pinheiro, Helena M.; Machado, Remígio; R. da Fonseca, M. Manuela; Sapatinha, Maria; Pires, Carla; Marmelo, IsaThe red macroalga Gelidium corneum is a species commercially exploited for agar extraction, though with enormous potential for other industrial applications. This work aimed to produce protein-rich extracts from the crude alga and from residues of the industrial agar extraction process by applying different extraction and recovery procedures, and to characterize the obtained protein extracts. The sequential imp...
Eco-innovative aquafeeds biofortified with asparagopsis taxiformis to improve t...
Marmelo, Isa; Lourenço-Marques, Cátia; Silva, Iris A.L.; Soares, Florbela; Pousão-Ferreira, Pedro; Mata, Leonardo; Marques, António; Diniz, Mário SousaExtreme weather events, like marine heatwaves (MHWs), are becoming more frequent and severe due to climate change, posing several challenges to marine ecosystems and their services. As disease outbreaks are often prompted by these acute phenomena, it is essential to develop ecoinnovative strategies that can efficiently improve farmed fish resilience, especially under suboptimal rearing conditions, thereby ensur...
In vitro bioaccessibility of macro and trace elements in biofortified and conve...
Barbosa, Vera; Anacleto, Patrícia; Maulvault, Ana Luísa; Oliveira, Helena; Marmelo, Isa; Ferraris, Francesca; Raggi, Andrea; Ventura, MartaBiofortification is a promising strategy to improve the nutrient profile of farmed fish but requires consideration of the nutrient bioaccessible fraction. In this study, the in vitro bioaccessibility of macro and trace elements was investigated in biofortified and conventional farmed gilthead seabream and common carp, also taking into account the effect of cooking (by steaming). Biofortification enhanced iodine...
Proximate composition, physicochemical and microbiological characterization of ...
Campos, Bruno Miguel; Ramalho, Edgar; Marmelo, Isa; Noronha, João Paulo; Malfeito-Ferreira, Manuel; Mata, Paulina; Diniz, Mário SousaThe aim of this work was the study of the proximate composition and profile of fatty acids, minerals, and some microbiological aspects of four edible seaweed species (Chondrus crispus, Palmaria palmata, Porphyra sp., and Ulva sp.) available in the Portuguese market for food consumption, and produced in a national Integrated Multi-Trophic System (IMTA). Methods: Moisture, ash, and total lipids were determined gr...
