Latest Patents

Her latest patents include a plant-wall-rich product with enhanced water-soluble polysaccharide. This invention focuses on modifying plant wall-rich products to contain a higher fraction of water-soluble polysaccharides than what exists naturally. The process involves adding water to the natural product in a divided state, allowing it to undergo a shearing treatment. The resulting product is subjected to a shearing force before extrusion, leading to modified products that can be converted into powder. Through aqueous extraction performed directly on the extruded product, a water-soluble fraction is obtained, isolating components such as pectins with a degree of methylation greater than or equal to 75%. The extraction residue can be dried and ground to be used as alimentary fibers.
