MUMBAI, India, June 30 -- Intellectual Property India has published a patent application (202641075859 A) filed by Paavai Engineering College; Dr. M. Jayachitra; and Dr. S. Kailash on June 18, 2026, for Fabrication Of Composite Bio-Coating For Banana Shelf-Life Enhancement.
Inventors include Mr. G. Aravind Kumar; Mr. R. Selva Kumar; Mr. S. Vijayavelan; and Mr. R. Kavin Kumar.
The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: An edible, biodegradable composite bio-coating formulation and a method for its preparation and application for enhancing the postharvest shelf life of banana fruit are disclosed. The formulation comprises quinoa starch, milk whey, guar gum, glycerol and a plant-derived antimicrobial extract, combined in proportions optimised by a Central Composite Design based response surface methodology to simultaneously minimise ethylene production and weight loss, maximise firmness retention, and achieve satisfactory film integrity. The coating is prepared by a solution casting and homogenisation process and applied onto pre-treated banana fruit by dipping or spraying. The resulting semi-permeable coating suppresses the climacteric respiration and ethylene peaks of the fruit, moderates the activity of enzymes responsible for browning and softening, reduces crown and tail rot, and extends the period for which the coated fruit retains acceptable firmness, appearance, aroma and flavour, while remaining edible and readily removable by gentle washing in warm water prior to consumption, thereby providing a sustainable, non-toxic alternative to synthetic plastic-based postharvest packaging.
