MUMBAI, India, Aug. 12 -- Intellectual Property India has published a patent application (202611068444 A) filed by Chandigarh University on June 01, 2026, for Green Extraction System For Recovery Of Polyphenolic Compounds From Orange Peel Using Deep Eutectic Solvents.
Inventors include Rishabh Chaudhary; Aditee Singh; Dr. Ashok Prabhakar; and Pihu Vats.
The application for the patent was published on August 07, 2026, under issue no. 32/2026.
Abstract: The present invention relates to a green extraction system for recovering polyphenolic compounds from orange peel biomass using deep eutectic solvents (DES). The system comprises biomass pretreatment, DES preparation, solvent optimization, solid-liquid extraction, separation, and characterization units integrated into a sequential extraction architecture. A deep eutectic solvent comprising choline chloride and glycerol is utilized as an environmentally friendly extraction medium for selective dissolution of phenolic compounds through intermolecular hydrogen-bonding interactions. The process includes controlled water-assisted DES optimization, drying, grinding, sieving, and extraction under optimized temperature, agitation, extraction-duration, and solid-to-liquid ratio conditions. The extracted compounds are separated through centrifugation and characterized using UV-visible spectroscopy, FTIR, HPLC, and SEM techniques. The invention provides sustainable agro-waste valorization, enhanced phenolic recovery efficiency, reduced solvent toxicity, minimized environmental impact, and environmentally sustainable extraction of bioactive compounds from citrus processing waste.
