Process for tempering and milling grain

A method of milling grain, comprising, prior to milling, heating a quantity of grain kernels to at least a glass transition onset temperature to form heated softened grain kernels is disclosed. With this method, it has surprisingly been found that moisture tempering, in most instances, is no longer required as a conditioning step for milling. Depending on the temperature to which the grain is heated, the texture of the grain kernel can be moved to a variety of textures, including, but not limited to, a more leathery or rubbery texture. In an alternative embodiment, the heat tempering step is preceded by a moisture tempering step. The method increases overall yield and improves control of the milling process.
