The present disclosure provides processes for the production of protein and fibre compositions from brewer's spent grain. The process comprises micronising dried brewer's spent grain using a pin mill and fractionating the micronised brewer's spent grain using an air classifier. The present disclosure also provides protein and fibre compositions, processes for producing food products incorporating the protein or fibre compositions, and food products comprising the protein or fibre compositions.
