Effect of seaweed flakes addition on the development of bioactivities in functional Camembert-type cheese

The effect of adding Palmaria palmata or Saccharina longicruris to Camembert-type cheese on both the antioxidant capacity (ORAC) and Angiotensin I-converting enzyme (ACE)-inhibitory activity has been studied with the aim of developing a functional food. The nutritional composition showed that P.palmata had the highest total protein and carbohydrate contents while S.longicruris demonstrated the highest total fibre and minerals contents. The bioactivities determined in the S.longicruris soluble extract were the highest. Three cheese model curds were studied: cheese control (CC), 2% of P.palmata (C2PP) and 2% of S.longicruris (C2SL). During ripening (20days), the curd pH of all treatments was significantly similar, as their ORAC values, starting at 0 and reaching 41.28mmol TEg(-1). The ACE-inhibitory activity of the three treatments was significantly similar, at day 0 (13.20%) and day 20 (58.27%). The feasibility of including these two seaweeds into Camembert-type cheeses was validated through the adequate development of bioactivities during ripening supporting promising food applications.
