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
work compared two extraction techniques: conventional heat assisted extraction (HAE) and high
pressure assisted extraction (HPAE) to maximize the yield and the concentration of target compounds.
Different independent variables were considered for the response study. Time (t) and percentage
of ethanol of the solvent (S) were chosen for both techniques and temperature (T) and pressure (P)
were used for HAE and HPAE, respectively. The experiments were designed following a response
surface methodology (RSM) approach. The obtained results showed a similar nutritional composition
between algae samples: low-fat content and high content of proteins, carbohydrates and energy. All
tested algae showed good antioxidant and antimicrobial properties. Finally, HEA demonstrated to
be the most efficient extraction technique. This study confirms the potential of red algae to be part
of the human diet as a source of non-animal protein, due to its nutritional content, phenolic profile,
pigments concentration and bioactive properties, which proves that HAE is the optimum technique
for the extraction maximization.
