Conclusion

We have identified UV-protection and antioxidant activity as the functional properties of MAAs. Heat-treated MAAs lost their UV-protective activity, but were transformed into compounds with strong antioxidant activity over a wide range of pH. In a previous study, a similar compound was produced from laver porphyra-334.
