Cultured dextrose is a food additive used to inhibit the growth of undesirable bacteria and mold in food. Often used in place of Sodium benzoate, benzoates and Potassium sorbate, sorbates, it is considered by some consumers to be a more "natural" ingredient, because it is prepared by the fermentation of milk or sugar powders by the probiotic bacteria ''Propionibacterium freudenreichii'' and ''Lactococcus lactis'', both of which are extensively used in the production of cheese and other dairy products.
