Abstract
Abstract Coffee whitener compositions containing soy protein isolate will exhibit substantial resistance to "feathering" or oil separation in hot coffee provided that the soy is used in combination with caseinate. The caseinate is present in an amount of at least 0.9% based on the dry weight of the coffee whitener composition. Furthermore, by carefully correlating the combined amount of the soy and caseinate in the coffee whitener compositon with the relative ratio of soy:caseinate, the characteristic "feathering" from soy protein isolate is eliminated.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
84 words
A coffee whitener composition consisting essentially of sugar, fat, stabilizing salt, an emulsifier and a proteinaceous ingredient; said proteinaceous ingredient being present in an amount of from about 2 to about 10% by weight based on the dry weight of the whitener composition, said proteinaceous ingredient consisting essentially of soy protein isolate and caseinate in a weight ratio of soy protein isolate:caseinate of from about 10:90 to about 80:20, provided that at least about 0.9% by dry weight of the whitener composition is casein.
Claim 2
Dependent Claim
