MAIN ACTIVE ELEMENTS AND THEIR PROPERTIES (Unit of measurement : mg/100g)
Many research projects concerning the lipidic elements of Porphira umbillicalis have shown the presence of essential polyunsaturated fatty acids.
These acids are essential for the human organism because it is not able to synthesise them on its own. Thus, they can be taken only via exogenous channels with food. Porphira umbilicalis is especially rich in polyunsarurated fatty acids: linoleic acid,linolenic acid,gamma-linolenic acid, eicosapentaenoic acid (EPA) , docohexaenoic acid (DHA).
Linoleic and Linolenic acids
These compounds are also classified as Vitamin F. The organism transforms linoleic into linolenic acid through enzymatic action. They have a structural role because they constitute the basis for the synthesis of prostaglandin (PGE1). Like certain vitamins, linoleic acids do not exhibit, in themesves, biological activity, they require bio-chemical transformations within the organism.
EPA and DHA acids.
These inhibit the aggregation of platelets. They have a preventive role against arteriosclerosis since they reduce the amount of cholesterol and triglycerides in the blood. The fatty acids of Porphira umbilicalis are to be distinguished by the absence of the characteristic smell of fish and they are more resistent to oxidation.
Also known as Provitamin A, Beta carotene is transformed into Vitamin A in the human organism. Vitamin A is liposoluble and plays a fundamental role in growth, in the building of the skeletal structure and in regeneration of tissues. Furthermore, Vitamin A improves resistance to infection, acts on the functions of the retina (visual sharpness) and controls the entire hormonal system. It has antioxidant and anti-free radical properties, it participates in epidermic cellular activity, reinforces the cutaneous defences and protects the skin against dehydration. Beta carotene has been successfully tested as a protective substance against cancer of the skin. If taken as an aliment, it helps reduce the risk of cancer due to exposure to ultraviolet rays.
Grazie ad un processo di estrazione mediante reazione alcalina, si è potuto verificare che tra le proteine di Porphira unbilicalis vi è una costante presenza di nitrogeni (dall'11% al 14%). Gli amminoacidi sono piuttosto simili a quelli delle classiche proteine. La loro composizione è qualitativamente migliore rispetto a quelle delle piante terrestri poiché sono molto simili all'albumina contenuta nell'uovo.
Thanks to a process of extraction by means of alkaline reaction we have been able to verify that, among the Porphira unbilicalis proteins there is a constant presence of nitrogens (from 11 to 14%). The amino acids are quite similar to those of classical proteins. Their composition is qualitatively better, compared to those of terrestrial plants because they are very similar to the albumen contained in eggs.
