Food-Waste Valorisation: Synergistic Effects of Enabling Technologies and Eutectic Solvents on the Recovery of Bioactives from Violet Potato Peels

Potato peels are the food industry's biggest waste—but they might just be a hidden treasure chest of antioxidants, waiting to be unlocked with a little help from sound waves and microwaves.

These findings highlight a win-win: turning food waste into valuable bioactives while reducing environmental impact. The combination of NaDES with enabling technologies like ultrasound and microwaves could revolutionize how we recover antioxidants from agricultural by-products. As the circular economy gains momentum, this approach offers a practical, scalable solution—one that transforms a waste problem into a resource opportunity.

Key Points

• Ultrasound-assisted NaDES extraction boosts antioxidant yield 3.7-fold over conventional methods.
• NaDES extracts extend shelf-life by 5.6 times over 24 months.
• NaDES extracts show stronger antiproliferative activity against colon cancer cells.
