Abstract: The present work aimed to determine the nutritional composition (ash, protein, fat, car- bohydrate content and energy value), phenolic compounds, pigments and organic acids content of three typical red algae from the Northwest of Spain: Chondrus crispus, Mastocarpus stellatus, and Gigartina pistillata; as well as their antioxidant and antimicrobial activities. Furthermore, the present Citation: Carpena, M.; Caleja, C.; work compared two extraction techniques: conventional heat assisted extraction (HAE) and high Pereira, E.; Pereira, C.; Ciri´c,A.;´ pressure assisted extraction (HPAE) to maximize the yield and the concentration of target compounds.
