  • Patent number: 8652600
    Abstract: The invention relates to a method of producing an extrudate comprising the steps of providing a plant protein and treating said protein with a solution comprising a nitrogen-containing compound. The solution with the nitrogen-containing compound may moreover comprise an anti-oxidative acid. A product, such as a film, obtained by the method is also described. By using the solvent-free method of the invention, polymers with excellent barrier and tensile properties may be produced.
