Abstract
A method is described of using a surface-reacted calcium carbonate as an extrusion aid for the production of a puffed polysaccharide-based material, excluding fibrillated cellulose-containing materials. In embodiments, the surface-reacted calcium carbonate is a reaction product of ground natural calcium carbonate (GNCC) or precipitated calcium carbonate (PCC) with carbon dioxide.
