MUMBAI, India, Aug. 17 -- Intellectual Property India has published a patent application (202641096922 A) filed by Kondamudi Suman; Pandala Neha; and Aduri Ashitha on August 11, 2026, for Clitoria Ternatea Derived Carbon Dot Integrated Intelligent Food Spoilage Biosensor Film.
Inventors include Kondamudi Suman; Pandala Neha; and Aduri Ashitha.
The application for the patent was published on August 14, 2026, under issue no. 33/2026.
Abstract: The present disclosure relates to an intelligent colorimetric biosensor film comprising Clitoria ternatea flower-derived anthocyanin extract and green synthesized carbon dots for real-time monitoring of food spoilage. Carbon dots are prepared from Clitoria ternatea extract through a hydrothermal green synthesis process and incorporated into biodegradable polymer-based indicator films. The developed films exhibit pH-responsive colour changes upon interaction with volatile spoilage-associated compounds including ammonia, hydrogen sulfide, carbon dioxide, and biogenic amines released during food deterioration. The biosensor films provide visual detection of freshness changes in food products including meat, seafood, dairy products, mushrooms, and vegetables. The disclosed technology provides a sustainable, non- destructive, and visually interpretable approach for intelligent food packaging applications.
