Abstract: An oat composition comprising water, hydrolyzed oats, undissolved solids, dissolved solids, emulsifier, and suspension stabilizer. The hydrolyzed oats are 1 to 10% by weight of the oat composition and can be whole grain. The suspension stabilizer concentration is effective to maintain the undissolved solids in suspension in the oat composition upon activation so that at least 90% by volume of the oat composition is a single solid-in-liquid suspension at the end of a suspension test, where the solid-in-liquid suspension comprises water and a majority the undissolved solids in the oat composition. The viscosity of the oat composition is 6 to 30 cP at 8° C. at a shear rate of 50/s. The hydrolyzed oats are provided by hydrolyzing starch in starting oats comprising a pre-hydrolysis starch-to-protein mass ratio. The hydrolyzed oats comprise a post-hydrolysis starch-to-protein mass ratio equal to the pre-hydrolysis starch-to-protein mass ratio within a tolerance of +/?10%.
