Project Title:

Profiling and Optimising chemical composition of red Sea Vegetables for enhanced bioactive yields

Project Coordinator:

Dr Dagmar Stengel

Project Abstract

This project will characterise the bioactive profile of two edible red seaweeds (seavegetables), Carrageen Moss (Chondrus crispus) and Nori (Porphyra sp.), commercially available in Ireland. It will further investigate the potential to enhance, through optimised cultivation, specific bioactivities (anti-oxidant, antidiabetic, cardioprotective) in these species which at present are only harvested from the wild. A significant potential exists to include these species as functional food ingredients in Ireland, based on their availability and familiarity. Red algal proteins (including phycobilins) and mycosporine-like amino acids (MAAs) have proven antioxidant capacities, and in other countries both species are cultivated at large scale. Although traditionally harvested and accepted by Irish consumers into food products as Irish Moss and sushi, respectively, the biochemical composition of naturally collected materials, as currently available on Irish markets, and their related bioactivity has never been assessed. Building upon, and extending, expertise developed under NutraMara at NUI Galway (bioactive variability, biomass optimisation) and UL (peptide and protein extraction, bioactivity assessment), the natural variability of bioactive composition in these two species be quantified. Research outputs will identify processes that will allow the optimisation of these commonly available species for the Irish food market and underpin the future development of high value food products.
