MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202611114796 A) filed by Chandigarh University on September 25, 2026, for Voc-Triggered Autonomous Phase-Transition Membrane System For Food Shelf-Life Extension.
Inventors include Shaman Sharma; and Deepak Kumar.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The present invention relates to autonomous food-preservation materials. An 5 autonomous flexible membrane includes a layered polymer substrate, micro-reservoir matrix, VOC-trigger reactive zones, phase-transition lattice and reversible binding layer. The membrane is positioned in a food-storage micro-environment and remains in an absorptive micro-phase until spoilage-related VOCs reach a selected threshold condition. The membrane then changes to a lockdown phase in 10 which volatile triggers are bound to selectively inhibit a spoilage cascade. A visual phase indicator can provide a non-electronic colour-change indication of the membrane state. The membrane operates passively through diffusion kinetics, pressure gradient and VOC concentration, without electrical power, an actuator, electronic processing or external activation, and is suitable for crate liners and 15 packaging environments.
