“…The significant difference in moisture content between the experimental groups ( q < 0.05) may be related to differences in the lyophilization process and packaging conditions during transport to the laboratory. In terms of ash, proteins, lipids, and carbohydrates and others, the values obtained for FR and PT samples are in the range with those found by other researchers for Ulva genus ( Supplementary Table S4 ) [ 8 , 16 , 27 , 28 , 29 , 30 , 33 , 39 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 ]. However, it is of note that many of these studies used different analytical methodologies for determination of the proximate composition.…”

“…Beyond the influence of factors as geographical origin, harvest time, species-specific variations, and cultivation protocols [ 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 ], the variations between different studies may also be related to methodological differences. For example, the lipid content found in most of the studies ranged between 0.5–3% DW [ 8 , 27 , 28 , 29 , 30 , 33 , 39 , 62 , 63 , 64 , 67 , 68 , 69 ], but there were reported values up to 13.7% DW [ 70 ]. In fact, the high variability in the lipid content reported in the literature may also be related to different methods used, namely different adaptations of Bligh and Dyer and Folch methods or Soxhlet extraction used to obtain lipid extracts.…”

Macroalgae of the genus Ulva have long been used as human food. Local environmental conditions, among other factors, can have an impact on their nutrient and phytochemical composition, as well as on the value of the seaweed for food and non-food applications. This study is the first to initiate a comparison between commercial Ulva spp. from different European origins, France (FR, wild-harvested Ulva spp.), and Portugal (PT, farm-raised Ulva rigida), in terms of proximate composition, esterified fatty acids (FA), and polar lipids. The ash content was higher in PT samples, while FR samples had higher levels of proteins, lipids, and carbohydrates and other compounds. The profile of esterified FA, as well as FA-containing polar lipids at the class and species levels were also significantly different. The FR samples showed about three-fold higher amount of n-3 polyunsaturated FA, while PT samples showed two-fold higher content of monounsaturated FA. Quantification of glycolipids and phospholipids revealed, respectively, two-fold and three-fold higher levels in PT samples. Despite the differences found, the polar lipids identified in both batches included some lipid species with recognized bioactivity, valuing Ulva biomass with functional properties, increasing their added value, and promoting new applications, namely in nutraceutical and food markets.

“…are not only rich in essential PUFAs, but also contain high amounts of macroand micronutrients as reported previously [71]. In addition, the nutritional value of Ulva species in terms of carbohydrates, protein, and fatty acids (especially PUFA content) has been reported to be comparable to some vegetables, nuts, and grains [2,23,72] and it has been consumed traditionally for centuries in many Asian countries [1,2,4,25,72].…”

The fatty acid (FA) compositions of ten seaweeds representative of Chlorophyta, Rhodophyta, and Ochrophyta from Kuwait in the Arabian Gulf region were determined and are discussed in the context of their potential nutritional perspectives for seaweed valorization. All the seaweeds had higher saturated fatty acid (SFA) and lower monounsaturated (MUFA) and polyunsaturated fatty acid (PUFA) contents than those typical of tropical environments. Palmitic, myristic, stearic, oleic, linoleic, α-linolenic, and stearidonic acids were the major FAs detected. Arachidonic, eicosapentaenoic, and docosahexaenoic acids were detected in minor amounts. Conserved fatty acid patterns revealed phylogenetic relationships among phyla, classes, and orders matching the molecular phylogenies at higher taxonomic ranks. Hierarchical clustering analyses clearly segregated different seaweeds (except Codium papillatum and Iyengaria stellata) into distinct groups based on their FA signatures. All but one species (Chondria sp.) had health-beneficial n6/n3 PUFAs (0.33:1–2.94:1) and atherogenic (0.80–2.52) and thrombogenic indices (0.61–5.17). However, low PUFA/SFA contents in most of the species (except Ulva spp.) may limit their utilization in the formulation of PUFA-rich functional foods. Ulva spp. had substantially high PUFAs with PUFA/SFA >0.4, n6/n3 (0.33–0.66) and atherogenic (0.80–1.15) and thrombogenic indices (0.49–0.72), providing substantial potential for their utilization in food and feed applications.

“…Priyan, Kim, Kim, and Jeon (2019) also discussed that carbohydrates from Chlorophyta had been proven to exhibit many cosmeceutical properties such as antioxidant, anti-wrinkle and moisturizing properties. In a study conducted by Roleda et al (2021), they discussed the Chlorophyta sp. for its nutritional content that will benefit the public, anchored on the presence of polysaccharides, pigments, fatty acids, polyphenols and peptides.…”

Seaweeds are valuable marine plants that have garnered much attention from the public due to their high bioactive, nutrients and minerals content. Seaweeds have been used in multiple applications, including in cosmeceutical, nutraceutical and pharmaceutical industries. Nevertheless, this review will focus on the bioactive compounds of Chlorophyta and their potential application in nutraceutical and cosmeceutical industries. Chlorophyta are believed to possess a significant amount of nutrients and minerals, sufficient to meet the daily requirements of nutrients and minerals in the human body. Considering the nutritional aspect, deficiency in nutrients may lead to severe ailments, including heart disease, neurological disorder and cancer. The main compounds studied in this review are polysaccharides, proteins, amino acids, lipids, fatty acids, pigments, minerals, vitamins and secondary metabolites. Among all, polysaccharides are the most exploited compounds and used in many advanced applications in the nutraceutical and cosmeceutical industries. This review also offers insights into the beneficial biological properties of Chlorophyta, highlighting their potential in cosmeceutical and nutraceutical applications. Further research is required to highlight the Chlorophyta sp. aquaculture, its extraction method, and the most targeted bioactive compounds from the species. Therefore, the challenge is to increase public awareness of the promising application of this species in the nutraceutical and cosmeceutical industries.
