MUMBAI, India, Nov. 14 -- Intellectual Property India has published a patent application (202441036328 A) filed by Dr. Jayaram LN, Bengaluru, Karnataka, on May 8, 2024, for 'citrullus lanatus based pectin as a potential bioplastic for food packaging, preservation and other applications.'
Inventor(s) include Dr. Jayaram LN; Lakshmana NV; Nikhitha CR; Jagadesh; G Poojitha Krishna; and Dr. Pradeep H N.
The application for the patent was published on Nov. 14, under issue no. 46/2025.
According to the abstract released by the Intellectual Property India: "The present invention provides a sustainable approach for developing biodegradable bioplastic films from Citrullus lanatus (watermelon) rind. Pectin is extracted using an acid-based extraction method and blended with pharmacopeia-approved plasticizers, polyvinyl alcohol (PVA), and natural polymers to create composite films through a solution casting technique. These films are evaluated for their mechanical strength, biodegradability, water retention capacity, and surface morphology using analytical tools such as Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). The resulting films exhibit excellent tensile strength, rapid soil degradation, and effective moisture and pathogen barrier properties, making them a viable eco-friendly alternative to petroleum-based plastics for food packaging and preservation applications."
