A method for forming a grain composition includes mixing a first grain powder composition with water using a mixing apparatus to form a mixture. Mechanical energy applied to the mixture is calculated from the measured torque. The protein quality is expressed as the measured torque as a function of mechanical energy and is compared to a standard. If the protein quality of the first grain powder composition does not meet the standard, a second grain power composition is formed having a different weight percent of the first source of grain powder than the first grain powder composition.
