MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202631110133 A) filed by National Institute Of Technology Patna on September 14, 2026, for Food Freshness Assessment System.
Inventors include Chandan, Swet; Choubey, Vikas; and Upadhyay, Vikas.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: Embodiments of the present disclosure relate to a system (100) and a method (800) of food freshness assessment. The system (100) performs non-destructive food freshness assessment by processing multimodal information acquired through a sensor array (104). The system (100) includes a processor (102-2) receives gas-sensing, optical colour-sensing, thermal-sensing, and environmental data and normalizes corresponding sensor-channel values to a common numerical range. The processor (102-2) determines objective weights according to statistical dispersion and inter-channel correlation, thereby reducing the influence of redundant sensor channels. The processor (102-2) combines the normalized values using the determined objective weights to generate an index indicative of a food freshness state. The processor (102- 2) classifies the food according to the generated index and provides freshness information for monitoring. An alert unit (110) generates a notification upon detection of deterioration, while an actuator (112) performs a corresponding cold-chain control action.
