A composition is disclosed comprising a partially hydrolysed cereal protein. The partially hydrolysed cereal protein is characterised in that 20% to 80% by weight has a molecular weight of 25 kDa or greater 8% by weight or less has a molecular weight of 1.4 kDa or lower and in that it has a nitrogen solubility index of 90% or greater at pH 1 to 10. The preferred cereal protein derives from wheat. Also disclosed is a process for producing the composition comprising providing a slurry having a degree of hydrolysis of 3 to 8, determining the pH, adjusting the pH of the slurry and separating the aqueous-soluble portion of the slurry. Compositions according to the invention find use as milk protein replacements and as components in nutritional supplements, sports drinks, or food products including beverages.
