MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202511125055 A) filed by Chandigarh University, Mohali, Punjab, on Dec. 11, 2025, for 'controlled-release antimicrobial biopolymer film incorporating nano-encapsulated plant extract nanocomposites for fresh produce preservation.'
Inventor(s) include Kirti Babber; and Dr. Yogesh Kumar Ahlawat.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to an antimicrobial, biodegradable biopolymer film designed for active food packaging, particularly for fresh produce. The film is formed from a starch-chitosan matrix 102 integrated with nano-hybrid plant-extract carriers containing essential oils or phenolic compounds encapsulated within lipid-polysaccharide nanoemulsions and protected by cellulose- or chitin-based nano-shells. A reinforcement phase of cellulose nanofibres or nanoclay improves mechanical strength and barrier properties, while micro-encapsulated oxygen-scavenging agents reduce oxidation and browning. The film features a multi-trigger controlled-release mechanism activated by moisture, pH change, temperature, or microbial enzymes, enabling targeted antimicrobial action during spoilage. An adaptive dual-layer structure enhances moisture resistance and compatibility with produce physiology. The invention provides an eco-friendly, smart packaging solution that extends shelf life, minimizes post-harvest losses, and offers a natural alternative to synthetic plastics and chemical preservatives."
