Abstract
Refrigerated cultured dairy products such as yogurt having enhanced anti-mold stability are prepared by including minute quantities of a cultured dairy ingredient having been cultured with a propionic acid forming culture. The propionic bearing cultured dairy ingredient such as whey is added to a milk base that is then heat treated prior to inoculation and fermentation with a yogurt culture. Premature protein coagulation that can occur during the heat treatment step is minimized by adding minute quantities of a calcium sequestrant to the milk base.
Claims5
A process for preserving a cultured dairy food product against spoilage yeast, the process comprising the step of providing in a food product, that (a) is normally devoid of Propionibacterium, (b) contains less than 50% solids, and (c) is subject to spoilage by yeast, a metabolite-containing material that is produced by a culture of Propionibacterium and that contains metabolites other than propionic acid, the material being present in an amount sufficient that the metabolite inhibits the growth of the spoilage yeast and that the material provides less than 0.3% propionic acid in the food product and a calcium sequestrant in weight ratio of material to sequestrant ranging from about 1.5:1 to 10:1.
