Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
81 words
A process for making an improved food product comprising, forming an aqueous suspension of whey and yeast which contains 20% to 50% by weight whey solids, wherein the yeast is in the form of a yeast cream which contains from about 10% to 20% by weight solids and the whey is in the form of a suspension containing from about 3.0% to about 70% by weight solids, spray drying the thus formed suspension, and recovering the spray dried free flowing product.
Claim 2
Dependent Claim
81 words
A process for making an improved food product comprising, forming an aqueous suspension of whey and yeast which contains 20% to 50% by weight whey solids, wherein the yeast is in the form of a yeast cream which contains from about 10% to 20% by weight solids and the whey is in the form of a suspension containing from about 3.0% to about 70% by weight solids, spray drying the thus formed suspension, and recovering the spray dried free flowing product.
Claim 3
Dependent Claim
18 words
The process in claim 1 wherein the yeast cream is from about 17% to 18% by weight solids.
Claim 4
Dependent Claim
39 words
The process in claim 1 wherein the yeast-whey suspension is from about 15% to about 30% in total solids and of the total solids the whey is about 20% to 50%, and the yeast is about 80% to 50%.
Claim 5
Dependent Claim
