Hypothesis
This study aims to set the optimal conditions for the extraction of kiwifruit peels and to assess the biological activities of the extracted polyphenols.
Conclusion
The study found that infrared extraction was more efficient than water bath extraction for recovering phenolic compounds from kiwi peels, which also exhibited antioxidant, antibacterial, and anticancer properties.
Supporting Evidence
- The infrared extraction method yielded a total phenolic content of 21 mg GAE/g DM, which was 4.4 times higher than the water bath method.
- Both extraction methods showed antibacterial activity against Bacillus cereus and Staphylococcus aureus.
- The IR extract significantly reduced A549 lung cancer cell viability at 100 µg/mL.
Takeaway
Scientists figured out the best way to get healthy stuff from kiwi peels, which can help fight germs and cancer.
Methodology
The study used Response Surface Methodology to optimize extraction conditions and measured total phenolic content and biological activities using various assays.
