MUMBAI, India, Aug. 17 -- Intellectual Property India has published a patent application (202641082384 A) filed by Rajagiri College Of Social Sciences Autonomous on July 03, 2026, for Brewery Spent Grain Derived Bioplastics For Active Packaging Applications And Its Fabrication Process.
Inventors include Aswani R; Jiya Jose; Radhakrishnan Ek; and Sebastian Schwaminger.
The application for the patent was published on August 14, 2026, under issue no. 33/2026.
Abstract: The process for fabricating a brewery spent grain (BSG) derived bioplastic film is disclosed. The process comprises preparing extractive-free BSG powder using an alcohol-acetone solvent mixture, followed by treatment with a deep eutectic solvent (DES) comprising choline chloride and oxalic acid to form a liquid mixture. The mixture is then diluted with distilled water to precipitate cellulose and lignin components, which are subsequently isolated by filtration, washed, and sonicated to form a cellulose-lignin slurry that is cast onto a substrate. To enhance the film properties, the cellulose-lignin slurry or the isolated cellulose can be incorporated into a chitosan solution, optionally blended with a starch solution and plasticized with glycerol. Furthermore, an active packaging agent such as coumarin is integrated into the composite mixture to yield an active, bio-based packaging film.
