Natural deep eutectic solvent-based supramolecular solvent/equilibrium solution for the extraction of gingerols from ginger

Ginger's pungent kick comes from gingerols—but extracting them efficiently has always been a challenge. Now, a natural deep eutectic solvent-based supramolecular solution offers a greener, smarter way to capture these valuable compounds.

Spice by-products are often thrown away, yet they hold a treasure trove of bioactive chemicals. From phenolics to essential oils, these residues can do more than sit in a landfill—they can become smart packaging materials that respond to pH, humidity, and temperature. This review dives into how these waste materials are transformed into films, coatings, and nanoemulsions using green extraction techniques.

Key Points

• Spice waste yields bioactive compounds for smart packaging.
• Ginger and onion boost antioxidant and antimicrobial properties.
• Green extraction turns residues into films and coatings.
