Abstract

Spray dried nutritional powders include soluble calcium, protein, and at least one of a soluble citrate, a soluble phosphate, and combinations thereof as at least one chelating agent. At least a portion of the soluble calcium is calcium HMB. At least a portion of the protein is soluble protein. The spray dried nutritional powders have a weight ratio of soluble calcium binding capacity to total soluble calcium of from about 2.3:1 to about 12:1. The calcium HMB, the at least one chelating agent, and the protein are spray dried together.

First claim

What is claimed is:

1. A method of preparing a nutritional powder comprising spray dried calcium beta-hydroxy-beta-methylbutyrate (HIVIB), the method comprising:
preparing an aqueous slurry by admixing at least one chelating agent followed by soluble calcium to water, wherein at least a portion of the soluble calcium is calcium HMB and wherein the at least one chelating agent is selected from the group consisting of a soluble citrate, a soluble phosphate, and combinations thereof;
holding the aqueous slurry under agitation for at least 10 minutes;
admixing protein to the aqueous slurry containing the chelating agent and the soluble calcium, wherein at least a portion of the protein is soluble protein; and
spray drying the aqueous slurry to produce the nutritional powder,
wherein the powder has a weight ratio of soluble calcium binding capacity to total soluble calcium from about 2.3:1 to about 12:1.

2. The method of claim 1 , further comprising:
admixing carbohydrate to the aqueous slurry prior the addition of the protein.

3. The method of claim 2 , further comprising:
admixing fat into the aqueous slurry after the addition of the carbohydrate but prior to spray drying.

4. The method of claim 2 , further comprising dryblending additional carbohydrate into the nutritional powder following the spray drying.

5. The method of claim 1 , wherein the powder comprises from about 0.1% to about 8% by weight of calcium HMB.

6. The method of claim 5 , wherein the powder comprises from about 12% to about 30% protein, from about 30% to about 80% carbohydrate, and from about 10% to about 35% fat, all by weight of the nutritional powder.

7. The method of claim 1 , wherein the at least one chelating agent is selected from the group consisting of tricalcium phosphate, dipotassium phosphate, disodium phosphate, and potassium citrate.
