Irish edible brown (Himanthalia elongata—sea spaghetti, Alaria esculenta—Irish wakame) and red seaweeds (Palmaria palmata—dulse, Porphyra umbilicalis—nori) were assessed for nutritional (proximate composition; salt; pH; amino acid; mineral and dietary fibre contents); bioactive (total phenolic content (TPC) and in vitro antioxidant activity (DPPH and FRAP)); thermal (thermogravimetric analysis (TGA)); and technological (water holding capacity (WHC), oil holding capacity (OHC) and swelling capacity (SC)) properties. Red seaweeds had higher (p p p Irish wakame > dulse (p p p < 0.05) OHC than the brown seaweeds. Results demonstrate the potential of seaweeds as functional food product ingredients.
