Presentation<\/strong><\/strong><\/span><\/h2>\n\n\n\n

Tetraselmis<\/em><\/strong> is <\/strong> a marine microalga, unicellular with 4 flagella, about fifteen microns in diameter. The most widely used is the chuii species, named Tetraselmis<\/em><\/strong> chuii<\/em><\/strong> Butcher. Discovered by Butcher in 1959, some thirty species of Tetraselmis have already been catalogued. The two most widely used and studied species are chuii and suecica.<\/span><\/p>\n\n\n\n

The micro-alga Tetraselmis<\/em><\/strong> chuii <\/strong> was included in the positive list of novel foods published by the European Regulatory Office in 2017. Its properties enable it to be marketed as a food supplement [*]<\/a>.<\/span><\/p>\n\n\n\n

It has long been used in aquaculture to feed crustacean larvae, fry and small fish. Its lipid content, around 10% of dry biomass, has sparked interest in the development of algae production for biofuels.<\/span><\/p>\n\n\n\n

Over the past twenty years, algae have also been studied for their beneficial health properties. These appear to be mainly linked to the carotenoids and polyunsaturated fatty acids (PUFAs) [**<\/a> ] in which it is rich. On average, it contains 5 times more omegas than chlorella<\/a>, which is already well endowed with omegas 3 (DHA and EPA) [***]<\/a>.<\/span><\/p>\n\n\n\n

<\/a>Health properties<\/span><\/h2>\n\n\n\n

Its effects are mainly attributed to its high content of polyunsaturated lipids (PUFA), notably omega 3<\/a>, and carotenoids. Tetraselmis has the following properties:<\/span><\/p>\n\n\n\n

– Antioxidant<\/a><\/span>
– Antifungal<\/span>
– Skin<\/a> protection, anti-aging<\/span>
– Anti-inflammatory<\/span>
– Anti-cancer<\/span><\/p>\n\n\n\n

<\/a>Physical and organoleptic characteristics<\/span><\/h2>\n\n\n\n

Dried Tetraselmis chuii comes in the form of a pretty green powder with a pronounced seafood taste. It is highly prized in culinary preparations and already used by some of the world’s top chefs, who are at the forefront of new flavors.<\/span><\/p>\n\n\n\n

<\/a>How to use dried Tetraselmis chuii<\/span><\/h2>\n\n\n\n

Dried Tetraselmis chuii is a food and can be consumed as a dietary supplement, thanks to the precious elements it contains. According to the official bodies that have accepted this new algae onto the positive list of novel foods, it can be consumed up to 0.5 g per day.<\/span><\/p>\n\n\n\n

It is used in cooking to give dishes a subtle shellfish flavor and a natural green color. It is often blended with chlorella and spirulina for a combination of taste and color.<\/span><\/p>\n\n\n\n

<\/a>Proven benefits, scientific publications<\/span><\/h2>\n\n\n\n

Microalgae are natural sources of polyunsaturated lipids, particularly omega 3, which are invaluable for our health (Lee I Han 2015) [1]<\/a>. Austrian researchers published in 2015 (Faruq Ahmed and co.) [2]<\/a> a ranking of the microalgae richest in PUFA [**]<\/a>. It appears that Tetraselmis suecica is one of the top 4 microalgae containing the most carotenoids, alongside Dunaliella salina, Isochrysis galbana and Pavlova salina.<\/span><\/p>\n\n\n\n

These microalgae should see strong industrial development in the near future, thanks to the sources of natural carotenoids they represent. For the time being, they are already widely used in aquaculture, notably in hatcheries.<\/span><\/p>\n\n\n\n

In view of this major challenge, researchers have studied variations in lipid content, particularly in omega 3, as a function of production conditions. It turns out that light intensity and salinity conditions are sensitive factors with regard to the microalgae’s final characteristics (Adarme Vega 2014) [3]<\/a>, (Mohammadi 2015) [4]<\/a> (Mouna Dammak 2016) [5]<\/a>.<\/span><\/p>\n\n\n\n

Tetraselmis has the following properties:<\/span><\/p>\n\n\n\n

– Antioxidant (Banskota 2013) [6]<\/a>, (Amna Kashif 2018) [7]<\/a>.<\/span>
– Antifungal (Amna Kashif 2018) [7]<\/a><\/span>
– Skin protectant, Anti-aging (Carballo-Cardenas 2003) [8<\/a> ] (Jo, WS Cho 2010) [9]<\/a><\/span>
– Anti-inflammatory (Jo, WS Cho 2010) (Nauroth 2010) [10]<\/a> (Mobraten 2013) [11<\/a> ] (Ruairi Robertson 2015) [12<\/a>]<\/span>
– Anti-cancer: anti-apoptotic, anti-apoptotic, anti-angiogenic (Maeda 2018) [13]<\/a>(Spencer 2009)[14<\/a>]<\/a><\/a><\/span><\/p>\n\n\n\n

The anti-inflammatory effects ofalgae<\/a> extracts have been highlighted by numerous researchers.<\/span><\/p>\n\n\n\n

Mobraten and his team [11]<\/a> demonstrate the anti-inflammatory properties of PUFA’s [**]<\/a>. They conclude their studies by noting the influence of polyunsaturated lipids such as EPA, DHA and AA [***<\/a> ] on inflammatory processes. According to the researchers, knowledge of the actions of these precious lipids could help in the fight against inflammatory diseases, particularly those linked to chronic intestinal inflammation.<\/span><\/p>\n\n\n\n

Canadian researchers have demonstrated the powerful antioxidant activity of T.chuii (Banskota 2013) (9). Korean researchers have also confirmed the antioxidant properties of Tetraselmis microalgae. Their results also led them to show the antifungal activity and tyrosinase (*) inhibitory effects[****]<\/a> of certain water-soluble polysaccharides, extracted from Tetraselmis (Amna Kashif 2018) (10).<\/span><\/p>\n\n\n\n

Dutch researchers highlight the protective effects of Tetraselmis suecica by the fact that it also contains vitamin E, recognized for its antioxidant virtues (Carballo-Cardenas 2003) [8<\/a>]. Korean researchers have published results confirming the UVB-protective effects of Tetraselmis suecica extracts on the skin (Jo, WS Cho 2010) [9<\/a>].<\/span><\/p>\n\n\n\n
