PURPOSE:A novel compounded material containing propionic acid in a stable form, useful for fungusproofing of feed or food, obtained by blending three components of liquid volatile propionic acid, sodium propionate having high moisture absorbing properties, and calcium propionate having low antifungal properties. CONSTITUTION:(1mol) Propionic acid is blended with (0.1-10mol, preferably 0.25-6.25mol) sodium propionate and (0.1-5mol, preferably 0.5-2.5mol) calcium propionate, heated at 50-140 deg.C, dissolved, and the prepared solution is gradually cooled, solidified, to give a novel compounded material. The compounded material has hardly a pungent odor of propionic acid of its own, no high moisture absorbing properties of sodium propionate, and much more improved antifungal effect than sodium propionate and calcium propionate. The amount of the compounded material used is 0.01-1wt%, preferably 0.05-0.7wt% based on feed or food. |
