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.

Embodiments of the disclosure relate to a method of accelerating a malting process. In the method, a grain is steeped in water including -glucanase to produce chitted malt. The chitted malt is germinated to produce green malt, and during germinating, an aqueous mixture including -glucanase and Gibberellic acid is applied to the chitted malt. The green malt is then kilned to reduce the moisture content to produce a batch of malt. Advantageously, the finished batch of malt exhibits lower levels of deoxynivalenol contamination than conventional malts.
