Abstract
A mold inhibitor composition that has particular utility for the preservation of animal feeds, and a method of making such composition. The composition is an aqueous solution of one or more salts or propionic acid, one or more deliquescent materials, one or more humectants, and in certain forms of the invention monosodium glutamate is included. This composition makes propionate ions available for mold control just as effectively as propionic acid, but without either the bad odor or the serious corrosive characteristics of propionic acid. The deliquescent material serves the surprising function of keeping moisture from accumulating in feed adjacent the walls of feed bins or from condensing on the walls to minimize mold in this heretofore uncontrollable region. The method of the invention minimizes the normally severe precipitation problem that occurs when a base is mixed with propionic acid to form a propionate salt, by diluting out the number of molecules of the propionic acid and the base per unit of space as much as possible with the ingredients of the final product prior to the encounter between the propionic acid and the base.
