Abstract: Compositions and methods can be used to reduce the population of microorganisms present during the processing of grain and seeds. More specifically, microorganism levels are reduced in grain and seeds being malted by contacting the grain or seeds with a sanitizing solution that contains a peroxyacid and hydrogen peroxide. This is done shortly before steeping, the first step in malting procedures. Optionally, a sanitizing solution containing a peroxyacid and hydrogen peroxide may also be used at other points in the malting process.
