Abstract

Dairy compositions are provided having a high pH, of about 4.8 to about 6.2, comprising desirable probiotic cultures as well as an anti-microbial system for inhibiting undesirable pathogenic and/or spoilage microbial growth without significantly reducing the beneficial effect of the probiotic cultures.

Claims

1. A dairy composition having an aqueous continuous phase comprising:

a dairy component;

a microbial growth-inhibiting component selected from the group consisting of sorbic acid and salts thereof; and

a probiotic culture component comprising probiotic cultures dispersed in the dairy component, wherein the dairy composition has a pH of 5.0 to about 6.2, and the microbial growth-inhibiting component is present in an amount of about 0.03% to about 0.1% by weight of the dairy composition and the amount that is effective to (1) inhibit undesirable microbial growth and to permit the probiotic cultures of the probiotic culture component to remain substantially viable,

(2) maintain a total count of background flora in the dairy composition to within 3 log units over three days at 86°

F., and (3) inhibit the production of toxin in the dairy composition for at least 24 hours at a temperature of about 86°

F. when inoculated with C. botulinum.

2. The dairy composition of claim 1 wherein the microbial growth-inhibiting component is present in an amount of about 0.04% to about 0.08% by weight of the dairy composition.

3. The dairy composition of claim 1 wherein the probiotic culture component comprises probiotic cultures in an amount of about 1×

10⁴ cfu/g to about 1×

10¹⁰ cfu/g of the dairy composition.

4. The dairy composition of claim 1 further comprising:

one or more components selected from the group consisting of a flavor component, a fat component, a protein component, a prebiotic component, a sweetener component, a thickening component, a pH adjusting component, and combinations thereof.

5. The dairy composition of claim 1 further comprising:

a fat component comprising fat in an amount of less than about 20.0% by weight of the dairy composition.

6. The dairy composition of claim 1, wherein the reduction in viable probiotic cultures of the probiotic clulture component is less than about 1 log unit over about eight weeks at a temperature of less than about 45°

F.

7. The dairy product of claim 1, wherein the dairy product has a pH of at least 5.2.

8. The dairy composition of claim 1 wherein the probiotic cultures remain substantially viable in the dairy composition for about 8 weeks at a temperature of about 40°

F. to about 45°

F.
