Seasonal effect on the biochemical composition of Atlantic seaweeds cultivated ...
Mendes, Madalena Caria; Conde, Tiago; Moreira, Ana S. P.; Lopes, Diana; Pais, Ana Rita; Batista, Joana; Neves, Mariana; Salvador, MariaSeaweeds are recognized as sustainable food sources rich in nutrients and bioactive compounds, but their composition is highly influenced by seasonality. This study evaluated the biochemical profiles of Ulva sp., Fucus vesiculosus, Porphyra dioica, and Palmaria palmata cultivated in integrated multitrophic aquaculture across different seasons. Results showed marked seasonal and species-specific fluctuations. Po...
Seasonal biochemical fingerprints of outdoor cultivated Spirulina (Limnospira p...
Lopes, Diana; Moreira, Ana S. P.; Conde, Tiago; Ferreira, Andreia; Oliveira, Kayane; Conde, Alexandra; Ramos, Ana Alexandra; Pereira, HugoMicroalgae are increasingly recognized as sustainable bioresources with applications in food, feed, nutraceuticals, and aquaculture. Among them, Spirulina (Limnospira platensis) and Microchloropsis gaditana (formerly Nannochloropsis gaditana) stand out due to their rich biochemical composition with industrial applications and high market value. This study separately investigates the seasonal variability in the ...
Exploring the development of a clean-label vegan burger enriched with fermented...
Bassani, Joseane C.; Martins, Valter F. R.; Barbosa, Joana; Coelho, Marta; Sousa, Clara; Steffens, Juliana; Backes, Geciane T.; Pereira, HugoHaematococcus pluvialis and Porphyridium cruentum are red microalgae with high biotechnological potential due to their rich composition of bioactive compounds. However, their intense flavor limits their application in food products. This study evaluated the impact of fermentation with Lactiplantibacillus plantarum (30 ?C for 48 h; LAB-to-biomass ratio of 0.1:1; 106 CFU/mL) on the physicochemical and functional ...
Bioactive profile, bioaccessibility and antioxidant activity of diatoms: a comp...
Rocha, Helena R.; Coelho, Marta; Coelho, Natacha; Morais, Rui M. S. C.; Pintado, Manuela E.; Gomes, Ana M.Diatoms are microalgae with significant biotechnological potential due to their richness in bioactive compounds, including carotenoids and phenolics, contributing to their antioxidant properties. This study aims to compare the bioactive profile and antioxidant activity of three diatom species: Chaetoceros calcitrans, Nannofrustulum shiloi, and Cylindrotheca fusiformis cultivated in closed Flat Panel photobiorea...
Overview of polyphenolic composition and related biological activities of grape...
Dias-Costa, Rui; Coelho, Marta; Domínguez-Perles, Raúl; Gouvinhas, Irene; Barros, Ana NovoGrape stems, or stalks, are lignocellulosic by-products removed during the destemming process to reduce astringency in wine production. These by-products are a notable source of minerals and polyphenolic compounds, such as phenolic acids, stilbenes, proanthocyanidins and catechin derivatives, flavonols, flavones, and anthocyanins. These bioactive compounds have been associated with several beneficial effects on...
Breaking the silica barrier: optimising carotenoid extraction from diatoms
Rocha, Helena R.; Coelho, Marta; Sousa, Sérgio; Morais, Rui M. S. C.; Pintado, Manuela; Gomes, Ana M.Introduction: Diatoms are microalgae rich in bioactive carotenoids with antioxidant and health-promoting potential (1,2,3,4). However, their rigid silica frustules limit solvent penetration, hindering efficient carotenoid extraction and concealing their true content (5). This study investigates physical and chemical treatments to disrupt the silica structure of Chaetoceros calcitrans, Nannofrustulum shiloi, and...
Linking bioaccessibility and carotenoids to antioxidant activity in diatoms
Rocha, Helena R.; Coelho, Marta; Coelho, Natacha; Morais, Rui M. S. C.; Pintado, Manuela; Gomes, Ana M.Diatoms are photosynthetic microalgae with a siliceous cell wall and remarkable adaptability, making them a sustainable and renewable resource for high-value bioactive compounds (1,2). Their rapid growth, efficient carbon fixation, and minimal land and freshwater requirements (1,2) position them as attractive candidates for the development of eco-friendly products in the nutraceutical, pharmaceutical, and cosme...

Unlocking biochemical profile of chaetoceros calcitrans, cylindrotheca fusiform...
Moreira, Ana S. P.; Rocha, Helena R.; Aveiro, Susana; Ferreira, Andreia S.; Oliveira, Kayane; Conde, Alexandra; Coelho, MartaDiatoms have garnered attention as sources of natural bioactive compounds, making them attractive for developing high-value products for different biotechnological ends, particularly for nutritional applications. Despite their potential, the chemical composition of industrially produced biomass remains largely underexplored. In this context, this study was focused on a thorough characterisation of the biochemic...
