Abstract
A metabolite material of propionibacteria, having a metabolite of molecular weight greater than 300, is added to a food product to inhibit the growth of gram negative psychotropic bacteria, yeast, mold, gram positive bacteria, or Listeria. The metabolite material may contain less than 0.02% propionic acid such that there is insufficient propionic acid per se to inhibit microbial growth. The metabolite material is produced by growing propionibacteria cells in a liquid growth medium to produce a mixture containing the metabolite material. The mixture can be concentrated and added to a food product as a concentrated liquid or powder. The metabolite material added to a food product may contain viable cells of propionibacteria.
