Abstract: A process for producing extended shelf-life ready-to-use milk compositions containing probiotics by ultrapasteurizing a milk composition, cooling the composition to about 20 to 30° C., and inoculating the composition with one or more aseptically prepared probiotic cultures. The resulting milk compositions are ready-to-use, have an extended shelf-life, and contain sufficient probiotics to be beneficial to the consumer, even after an extended shelf-life of more than 90 days. The resulting milk compositions are used to provide probiotics to consumers in an effort to improve the consumer's intestinal health.
