Scanning electron microscopy (SEM) images of the pristine whey protein-based layer as the inner layer of the laminate (a); the whey-based laminate treated with 2% CS+CSNPs CIN (b); the whey-based laminate treated with 2% CS+CSNPs ROS (c). Note that all the images are taken at 10,000× magnification for easier comparison.
