Hypothesis

The study aims to evaluate the antioxidant and antimicrobial activity of methanolic extracts of seaweeds to develop safer food preservatives.

Conclusion

The study found that Gelidiella acerosa has high antioxidant activity and Haligra sps shows significant antibacterial activity against Staphylococcus aureus.

Supporting Evidence

  • Gelidiella acerosa exhibited the highest DPPH scavenging activity among the seaweeds.
  • Haligra sps showed significant antibacterial activity against Staphylococcus aureus.
  • The total phenolic content of Gelidiella acerosa was significantly higher than that of other seaweeds.

Takeaway

This study looked at seaweeds to see if they can help keep food safe and fresh without using chemicals that might be harmful.

Methodology

The study involved collecting ten edible seaweeds and evaluating their antioxidant and antimicrobial activities using various assays.
