Abstract Despite edible seaweeds being a source of protein, amino acids, minerals and vitamins and being part of some traditional cuisines, they are not widely consumed and are not normally included within western diets. Some studies have reported a growing interest in seaweeds among consumers in some European countries; furthermore, there have recently been initiatives in the field of gastronomy to open up new prospects for the future consumption of edible seaweed. Within this context, this stu...

Recently isolated microalgae Tetraselmis sp. IMP3, Tetraselmis sp. CTP4, and Skeletonema sp. were studied. The three novel strains contained relatively high levels of polyunsaturated fatty acids (PUFA) and n3 PUFA. However, highly unsaturated n3 FA contents were relatively low (5.7–13.0% of the total FA). In general, eicosapentaenoic acid (EPA, 20:5 n3) contents were low (< 6.4% of the total FA). However, in Skeletonema biomass, EPA levels were higher than 10% of the total FA. α-Linolenic acid (...

In the last decades, the use of algae in biotechnology and food industries has experienced an exponential growth. Codium tomentosum is a green macroalgae with high biotechnological potential, due to its rich lipidome, although few studies have addressed it. This study aimed to investigate the seasonal changes in lipid and pigment profiles of C. tomentosum, as well as to screen its antioxidant activity, in order to evaluate its natural plasticity. Samples of C. tomentosum were collected in two di...

Abstract The optimization of processed meats through salt replacement using edible seaweeds may reduce the risk of chronic disease through reduction in dietary sodium. We investigated the impact of the inclusion of four selected seaweeds (1% w/w) in reformulated frankfurters in which salt addition and pork fat content was reduced by 50% and 21%, respectively, and where pork loin (longissimus dorsi muscle) was increased by 6%, compared to a Control. Two different types of red (Porphyra umbilicali...

Ragworms (Hediste diversicolor) cultured under integrated multi-trophic aquaculture (IMTA) conditions display an improved fatty acids (FA) profile than conspecifics from the wild, thus being more suitable for maturation diets of marine fish and shrimp. Nonetheless, their use may represent a potential pathway for pathogens. The objective of the present study was to determine if high-pressure processing (HPP), as an approach to safeguard microbiological safety, could promote significant shifts on ...

Seaweeds have received huge interest in recent years given their promising potentialities. Their antioxidant, anti-inflammatory, antitumor, hypolipemic, and anticoagulant effects are among the most renowned and studied bioactivities so far, and these effects have been increasingly associated with their content and richness in both primary and secondary metabolites. Although primary metabolites have a pivotal importance such as their content in polysaccharides (fucoidans, agars, carragenans, ulva...

© 2018 The Authors Background & aims: There is a large body of evidence which supports the role of inflammation in the pathophysiology of mental health disorders, including depression. Dietary patterns have been shown to modulate the inflammatory state, thus highlighting their potential as a therapeutic tool in disorders with an inflammatory basis. Here we conduct a systematic review and meta-analysis of current literature addressing whether there is a link between the inflammatory potential of ...

Palmaria palmata is an edible red macroalga widely used for human consumption and valued for its high protein value. Despite its low total lipid content, it is rich in eicosapentaenoic acid (EPA). This seaweed has been scarcely explored with regard to its lipid composition. The polar lipids of seaweeds are nowadays recognized as important phytochemicals contributing to their add value valorization and providing support for claims of potential health benefits. The present study aimed to disclose ...

Cancer remains one of the most lethal diseases worldwide. There is an urgent need for new drugs with novel modes of action and thus considerable research has been conducted for new anticancer drugs from natural sources, especially plants, microbes and marine organisms. Marine populations represent reservoirs of novel bioactive metabolites with diverse groups of chemical structures. This review highlights the impact of marine organisms, with particular emphasis on marine plants, algae, bacteria, ...

Abstract The valorization of seaweeds has generated unprecedented interest in recent years due to their unique chemical characteristics. The taxonomic differentiation between Chlorophyta, Rhodophyta, and Ochrophyta is often supported by their contrasting chemical characteristics. Polar lipids are the most abundant class of lipids in several seaweeds species often labelled as valuable phytochemicals. Nevertheless, little is still known about how the polar lipidome of seaweeds varies within and am...

There is a growing trend to explore microalgae as an alternative resource for the food, feed, pharmaceutical, cosmetic and fuel industry. Moreover, the polar lipidome of microalgae is interesting because of the reports of bioactive polar lipids which could foster new applications for microalgae. In this work, we identified for the first time the Chlorococcum amblystomatis lipidome using hydrophilic interaction liquid chromatography-high resolution electrospray ionization- tandem mass spectrometr...

Abstract The Red Sea coast is rich in different types of seaweeds, which are suggested to possess medicinal properties. In this study, methanolic extract of Chondrus Crispus (MEC), a species of red algae collected from the southeast coast of Jeddah, Saudi Arabia was prepared and analysed for its chemical composition, antioxidant, anti-inflammatory and cytotoxic properties. HPLC analysis revealed that flavonoids were found to be predominant constituents of MEC followed by phenols and tannins. Amo...
