Wheat Gluten-Laminated Paperboard with Improved Moisture Barrier Properties: A New Concept Using a Plasticizer (Glycerol) Containing a Hydrophobic Component (Oleic Acid)

<table>IR spectra for the samples containing 20 wt.% plasticizer in the amide I region. Sample notation: wt.% plasticizer-OA (wt.% oleic acid in the plasticizer mixture). For clarity the curves have been shifted vertically. Gluten refers to unprocessed wheat gluten.</table>
