This study revealed the practical relevance of PFCP as a good source of peptides and amino acids. PFCP has desirable solubility, good water-holding and fat-binding ability, foaming properties and emulsification stability indicating their possible use in different food formulations.
PFCP was found to be an effective antioxidant in different in vitro assays. A dose-dependent effect between PFCP concentration and antioxidant activity was found. The results of this study indicate that the peptidic fraction of carotenoproteins exhibited a good antioxidant activity compared to that of positive controls like BHA and they can be used in food systems as natural antioxidants. PFCP possess also showed a bioactive potential as demonstrated in the DNA nicked assay.
Further work should be done to isolate and identify some specific peptides in PFCP that are responsible for the overall antioxidant activity.
