Edible Seaweed

Overtime seaweeds have been used as a food mainly due to their high nutritional value. This type of food is considered as functional food and contributes to the nutritional human requirements, being beneficial to human health. In this study 13 edible seaweed samples acquired in the marked of São Paulo city were analyzed and the concentrations of elements Cl, K, Mg, Mn and Na were determined by Instrumental Neutron Activation Analysis (INAA). The following edible seaweeds were analyzed: Nori (Porphyra umbilicates); Hijiki (Hijikia fusiforme); Kombu (Laminaria sp.) and Wakame (Undaria pinnatifida) species from China, USA, Japan and South Korea. The Undaria pinnatifida species presented the highest Na concentration and the lowest K level. The highest variation was obtained for Mn in the Porphyra umbilicates species.

Abstract: Food supplements industries, an important place must be assigned to nutraceuticals containing microalgae, nowadays accounting for a large and rapidly expanding market. The marketed products are mainly based on production strains, i.e., Spirulina and Chlorella in the composite situation, since two of them are cyanobacteria and the second one is eukaryotic. In the marketed form and several utilizations, and peculiarities that need special attention and adequate studies. General report is about the current scientific knowledge on each microalga, in particular the nutritional value and properties in prevention and wellbeing. Second, original studies are presented concerning the quality control of marketed products. Quality control is act as key argument in nutraceuticals validation. Microalgae one of particular organisms that need specific approaches to check identity and validate properties of microalgae. The paper is dedicated to the need for specificity in uses and to considerations about the future of microalgae in food supplements in our daily needs. India is a country with heterogenic population having diverse food habits become a driving force in the shift towards a greater recognition between diet and health care in research the use of few natural unprocessed foods like blue-green algae “spirulina” which has a galaxy of nutrients as diet supplements. The purpose of the present review is to compile evidence regarding the health benefits of spirulina, amount of evidence on health benefits are its effect in preventing anaemia, blood sugar and obesity many health diseases. Keywords: Microalgae, Nutraceuticals, Omega fatty acids, Phycocyanin, Spirulina: Blue-Green Algae.

<p class="MediumGrid2"><strong>Background</strong>: Plants, including marine algae, produce allelochemicals that influence the growth, survival, and reproduction of other organisms.</p><p class="MediumGrid2"><strong>Questions</strong>: To identify natural algicidal or antifouling allelochemicals, we screened 18 common seaweed extracts for suppression of rhizoid and blade production in a convenient <em>Porphyra suborbiculata</em> monospore assay.</p><p class="MediumGrid2"><strong>Species study and data description</strong>: Addition of extract from the most potent phaeophyte, <em>Hizikia fusiformis</em>, suppressed rhizoid formation, rhizoid number, rhizoid length, blade formation, and blade length.</p><p class="MediumGrid2"><strong>Study site and dates</strong>: Seaweed thalli for methanol extraction were collected on the coast of Korea from October 2012 to July 2015.</p><p class="MediumGrid2"><strong>Methods</strong>: Extracts were tested using the <em>P. suborbiculata</em> monospore assay system.</p><p class="MediumGrid2"><strong>Results</strong>: The 50 % suppression doses were 15 <em>µ</em>g ml<sup>-1</sup> for rhizoid formation, 2.4 <em>µ</em>g ml<sup>-1</sup> for rhizoid number, 13 <em>µ</em>g ml<sup>-1</sup> for rhizoid length, 6 <em>µ</em>g ml<sup>-1</sup> for blade formation, and 11 <em>µ</em>g ml<sup>-1</sup> for blade length. The <em>H. fusiformis</em> extract also suppressed rhizoid and blade production in leafy green (<em>Ulva pertusa</em>) and brown (<em>Undaria pinnatifida</em> and <em>Ecklonia cava</em>) seaweed spores, as well as suppressing diatom settlement.</p><p><strong>Conclusions</strong>: The allelochemicals that suppressed or eliminated competing seaweed species may be efficacious for new seaweed control technologies, including the development of antifouling or algicidal agents based on natural products.</p>
