Product Laminarin Source Potential food application and other benefits Glucan polysaccharide found in brown seaweed. Iodine Brown algae It is an anti-coagulant and has prebiotic effects and anti-tumour properties, as well as the ability to decrease cholesterol absorption and modulate the immune system. It has been heralded as a potential cancer therapeutic as well as for its ability to repair wounds. Food supplements including brown seaweed extracts can be used in humans to treat iodine deficiency, goitre and myxoedema. Iodine from Undaria pinnatifida may also have an antitumorogenic role, inhibiting tumorogenesis. It has been suggested that the high seaweed content of the Japanese diet partially accounts for the low incidence of breast cancer among Japanese women. Bioactive amino acids Macroalgae Depress the contraction of excited smooth muscles, thus exerting a transitory hypotensive effect. Kainoid amino acids have high insecticidal properties. Due to their neuroexcitatory properties, such bioactive amino acids are currently been used in medical research concerning Alzheimer’s and Parkinson’s disease, as well as epilepsy Ulvan Green seaweed For the treatment of gastric ulcers. Ulvan is also known to modify the adhesion and proliferation of normal and tumoral human colonic cells, as well as strain-specific anti-influenza activities. Mannitol Brown seaweeed It can be used to replace sucrose in the production of sugar-free compound coatings. This presents part of the solution to diabetes, which is a growing problem in modern day society. Mannitol is also used as platform chemical by the industry. Chitosan Crustaceans Chitosan could be used for a wide range of applications due to its biodegradability, biocompatibility and antimicrobial activity. It can be formed into fibers, films, gels, sponges, beads or nanoparticles. Chitosan films have been used as a packaging material for the quality preservation of a variety of foods. Chitosan has high antimicrobial properties against a variety of pathogenic and spoilage microorganisms Substances derived from seaweed are currently used in many food products. E-numbers 400 up to 407 are all seaweed products.
