MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202621000153 A) filed by Ms. Pranali Dilip Bhagate; Mr. Shankar Jaiprakash Joshi; and Dr. Kiran Aanna Wadkar, Miraj, Maharashtra, on Jan. 1, for 'paper-based microfluidic device for rapid colorimetric detection of rancidity in edible oils.'
Inventor(s) include Ms. Pranali Dilip Bhagate; Mr. Shankar Jaiprakash Joshi; Dr. Kiran Aanna Wadkar; Dr. Santosh Maruti Gejage; Mr. Pranav Pandurang Ghatte; Ms. Prajakta Laxman Devkate; and Ms. Punam Shrikant Chougule.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "The present invention provides a paper-based microfluidic device designed for rapid, reliable, and non-instrumental detection of rancidity in edible oils. The device integrates an optimized microchannel architecture with a dedicated reagent zone containing a colorimetric formulation that selectively interacts with oxidative degradation products such as peroxides and aldehydes. When a small quantity of oil is applied to the sample inlet, capillary-driven flow transports it through the microfluidic pathway to the reagent zone, where a distinct and quantifiable color change is produced. This visual response enables users to assess the extent of oxidative spoilage without the need for laboratory equipment or technical expertise. The design emphasizes simplicity, affordability, and environmental sustainability by utilizing biodegradable paper substrates and minimal reagent quantities. The device demonstrates high sensitivity and reproducibility, making it suitable for routine screening of cooking oils across households, food service establishments, and manufacturing units. Its compact format and user-friendly operation address critical gaps in current oil-quality assessment methods, which often require complex instrumentation, longer processing times, or trained personnel. The invention thus offers a practical and commercially viable solution for on-site monitoring of edible oil freshness, ensuring improved safety, quality control, and consumer protection."
