Green extraction of phenolics and terpenoids from passion fruit peels using natural deep eutectic solvents

What if the secret to greener chemistry was hiding in fruit waste? Passion fruit peels, often discarded, hold valuable phenolics and terpenoids—and a new green method using natural deep eutectic solvents can unlock them.

Passion fruit peels are more than just kitchen scraps. They are packed with phenolics and terpenoids—bioactive compounds with antioxidant and aromatic potential. But extracting them has often relied on harsh, petroleum-based solvents. A new study offers a cleaner path: natural deep eutectic solvents (NADES).

NADES are a new class of green solvents made from natural components like sugars, organic acids, or choline derivatives. They are biodegradable, non-toxic, and highly tunable. The researchers used them to extract phenolics and terpenoids from passion fruit peels, showing that these eco-friendly solvents can effectively replace conventional ones.

The study focused on optimizing the extraction process to maximize yields of these valuable compounds. By adjusting parameters like solvent composition and extraction conditions, they demonstrated that NADES can achieve efficient extraction while keeping the process sustainable. This approach aligns with green chemistry principles, reducing environmental impact without sacrificing performance.

The implications are significant: turning agricultural waste into a source of high-value compounds using green solvents could transform the food and cosmetic industries. It’s a win-win for both industry and the planet.

Key Points

• NADES are green solvents from natural components.
• Optimized extraction of phenolics and terpenoids from peels.
• Sustainable alternative to petroleum-based solvents.
