Hypothesis
This study aims to optimize the extraction of carotenoids from different species of seaweeds using a Box–Behnken design.
Conclusion
Microwave-assisted extraction under optimized conditions is an effective and sustainable approach for carotenoid extraction from seaweeds.
Supporting Evidence
- Microwave-assisted extraction was found to be more efficient than traditional methods.
- The optimal extraction conditions were identified as a solid-to-solvent ratio of 1/13.6 g/mL at 60 °C for 15 minutes.
- Carotenoid content was significantly higher at elevated temperatures.
- Fucoxanthin and β-carotene were the predominant carotenoids identified in the extracts.
- The study highlights the potential of seaweeds as functional foods to enhance carotenoid intake.
Takeaway
Scientists figured out the best way to get healthy pigments from seaweeds using microwaves, which helps make the process faster and better for the environment.
Methodology
The study used microwave-assisted extraction and response surface methodology to optimize extraction conditions for carotenoids from various seaweeds.
Limitations
The study did not address the potential effects of pollutants in seaweeds on health.
