Method of producing a high-protein food product from brewery's spent grain

Abstract

The present invention provides a method of producing a grain derived high-protein food product, comprising the steps of: a) providing a biomass substrate, wherein said biomass substrate comprises at least one type of grain, preferably brewer's spent grain; b) subjecting said biomass substrate to a heat treatment in order to sterilize the substrate; c) inoculating the sterilized substrate obtained from step b) with a fungal strain; and preferably forming the substrate into a predetermined shape suitable for a solid flatbed culture; and d) incubating the inoculated biomass substrate obtained in step c) at 15-30° C. in an aerobic environment to grow a network of fungal mycelium into the biomass substrate in order to improve the structure and flavor of the product. The present invention also provides a novel Pleurotus ostreatus strain.
