Abstract
Abstract Cheese flavoring agents and cheese flavor enhancers are provided in the form of enzyme-modified, lactose-hydrolyzed whey or whey fractions. The products have a flavor profile characteristic of aged cheese and a flavor intensity sufficient to serve as the sole source of cheese flavor or as a cheese flavor enhancer in a variety of food products.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
63 words
A cheese flavoring agent comprising hydrolyzed, enzymatically modified whole whey, said whole whey having had an initial lactose content of from about 2 percent to about 90 percent on a dry weight basis, said hydrozylate resulting from enzymatically modifying the whole whey with lipase, protease, or a combination of lipase and protease, and lactose hydrolyzing at least 30% of the initial lactose content.
Claim 2
Dependent Claim
63 words
A cheese flavoring agent comprising hydrolyzed, enzymatically modified whole whey, said whole whey having had an initial lactose content of from about 2 percent to about 90 percent on a dry weight basis, said hydrozylate resulting from enzymatically modifying the whole whey with lipase, protease, or a combination of lipase and protease, and lactose hydrolyzing at least 30% of the initial lactose content.
Claim 3
Dependent Claim
27 words
The cheese flavoring agent of claim 1, in which the whey had a lactose content, before hydrolysis, of from about 20 to about 85 percent by weight.
Claim 4
Dependent Claim
18 words
The cheese flavoring agent of claim 1 in which the lactose is at least about 40 percent hydrolyzed.
Claim 5
Dependent Claim
18 words
The cheese flavoring agent of claim 1 in which the lactose is at least about 70 percent hydrolyzed.
Claim 6
Dependent Claim
28 words
The cheese flavoring agent of claim 1 in which the whey had a protein content, before enzyme modification, of from about 8 to about 60 percent by weight.
Claim 7
Dependent Claim
36 words
The cheese flavoring agent of claim 5 in which the whey had a lactose content, before hydrolysis, of from about 20 to about 85 percent by weight, which lactose is at least about 40 percent hydrolyzed.
Claim 8
Dependent Claim
18 words
The cheese flavoring agent of claim 6 in which the lactose is at least about 70 percent hydrolyzed.
Claim 9
Dependent Claim
25 words
The cheese flavoring agent of claim 1 wherein the whey or whey fraction is enzyme modified with calf lipase, kid-lamb lipase and fungal protease enzymes.
Claim 10
Independent Claim
100 words
A method for producing a whole whey-base cheese flavoring agent or cheese flavor enhancer which comprises the steps of: (a) enzymatically modifying whole whey with a protease or a combination of lipase and protease so as to provide a cheese flavor; and (b) hydrolyzing at least about 30 percent of the lactose component of the whole whey, the whey having had, before enzyme modification and lactose hydrolysis, a protein content of from about 2 to about 90 percent on a dry weight basis and a lactose content of from about 5 to about 85 percent on a dry weight basis.
Claim 11
Independent Claim
100 words
A method for producing a whole whey-base cheese flavoring agent or cheese flavor enhancer which comprises the steps of: (a) enzymatically modifying whole whey with a protease or a combination of lipase and protease so as to provide a cheese flavor; and (b) hydrolyzing at least about 30 percent of the lactose component of the whole whey, the whey having had, before enzyme modification and lactose hydrolysis, a protein content of from about 2 to about 90 percent on a dry weight basis and a lactose content of from about 5 to about 85 percent on a dry weight basis.
Claim 12
Dependent Claim
25 words
The method of claim 9 in which the whey had a lactose content, before hydrolysis, of from about 20 to about 85 percent by weight.
Claim 13
Dependent Claim
16 words
The method of claim 9 in which the lactose is at least about 40 percent hydrolyzed.
Claim 14
Dependent Claim
16 words
The method of claim 9 in which the lactose is at least about 70 percent hydrolyzed.
Claim 15
Dependent Claim
26 words
The method of claim 9 in which the whey had a protein content, before enzyme modification, of from about 8 to about 60 percent by weight.
Claim 16
Dependent Claim
34 words
The method of claim 13 in which the whey had a lactose content, before hydrolysis, of from about 20 to about 85 percent by weight, which lactose is at least about 40 percent hydrolyzed.
Claim 17
Dependent Claim
16 words
The method of claim 14 in which the lactose is at least about 70 percent hydrolyzed.
Claim 18
Dependent Claim
20 words
The method of claim 9 wherein the whey is enzyme modified with calf lipase, kid-lamb lipase and fungal protease enzymes.
Claim 19
Independent Claim
94 words
A method for producing a whole whey-base cheese flavoring agent or cheese flavor enhancer which comprises the steps of: (a) hydrolyzing at least about 30 percent of the lactose component of whole whey, said whey having an initial protein content of from about 2 to about 90 percent on a dry weight basis and a lactose content of from about 5 to about 85 percent on a dry weight basis; and (b) subsequently enzymatically modifying said hydrolyzed whey with a protease or a combination of lipase and protease thereby providing a cheese flavoring agent.
Claim 20
Independent Claim
94 words
A method for producing a whole whey-base cheese flavoring agent or cheese flavor enhancer which comprises the steps of: (a) hydrolyzing at least about 30 percent of the lactose component of whole whey, said whey having an initial protein content of from about 2 to about 90 percent on a dry weight basis and a lactose content of from about 5 to about 85 percent on a dry weight basis; and (b) subsequently enzymatically modifying said hydrolyzed whey with a protease or a combination of lipase and protease thereby providing a cheese flavoring agent.
