Abstract
Abstract The present invention is directed to a natural cheese product having a highly intensified American cheese flavor and to a method for preparing such cheese product. The cheese product is adapted for use as a cheese flavoring ingredient in cooked products, for example, process cheese. In the method, curd particles are produced, mixed with salt, a source of a lipolytic enzyme, and a source of a proteolytic enzyme, and cured for a period of time sufficient to produce increased levels of C 2 -C 10 fatty acids as compared to conventional American-type cheese.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
135 words
A method for the manufacture of natural American-type cheese having highly intensified American cheese flavor components, comprising preparing cheese curd from a milk source by an American cheese make procedure, separating the curd from the whey, salting the curd, adding to the curd a source of a proteolytic enzyme and a source of a lipolytic enzyme selected from calf throat tissue lipase, kid throat tissue lipase, lamb throat tissue lipase, and mixtures thereof, and curing said curd at a temperature above about 50° F., the amount of lipolytic enzyme and the duration of curing being selected to provide a total free C 2 -C 10 fatty acid content in said cheese of at least about 0.46 percent by weight and a free C 4 fatty acid content of at least about 0.32 percent by weight.
Claim 2
Independent Claim
135 words
A method for the manufacture of natural American-type cheese having highly intensified American cheese flavor components, comprising preparing cheese curd from a milk source by an American cheese make procedure, separating the curd from the whey, salting the curd, adding to the curd a source of a proteolytic enzyme and a source of a lipolytic enzyme selected from calf throat tissue lipase, kid throat tissue lipase, lamb throat tissue lipase, and mixtures thereof, and curing said curd at a temperature above about 50° F., the amount of lipolytic enzyme and the duration of curing being selected to provide a total free C 2 -C 10 fatty acid content in said cheese of at least about 0.46 percent by weight and a free C 4 fatty acid content of at least about 0.32 percent by weight.
Claim 3
Dependent Claim
27 words
A method in accordance with claim 1 wherein the milk source is inoculated with a source of a proteolytic micrococcus, a self-limiting lipase, and a flavoring microorganism.
Claim 4
Dependent Claim
23 words
A method in accordance with claim 2 wherein a source of a proteolytic micrococcus and a flavoring microorganism are added to the curd.
Claim 5
Dependent Claim
20 words
A method in accordance with claim 1 wherein the curing temperature is between about 50° F. and about 85° F.
Claim 6
Dependent Claim
20 words
A method in accordance with claim 3 wherein the curing temperature is between about 50° F. and about 85° F.
Claim 7
Dependent Claim
35 words
A method in accordance with claim 2 wherein calf throat tissue lipase, kid throat tissue lipase, lamb throat tissue lipase, and mixtures thereof are the source of both the lipolytic enzyme and the proteolytic enzyme.
Claim 8
Dependent Claim
30 words
A method in accordance with claim 1 wherein the source of proteolytic enzyme is selected from papain and proteases derived from A. oryzae, A. flavus-oryzae, B. subtilus, and mixtures thereof.
Claim 9
Dependent Claim
28 words
A method in accordance with claim 1 wherein the lipase is present at a level of between about 20 and about 45 grams per 100 pounds of curd.
Claim 10
Dependent Claim
28 words
A method in accordance with claim 8 wherein the protease is present at a level of between about 1 and about 10 grams per 100 pounds of curd.
Claim 11
Dependent Claim
18 words
A method in accordance with claim 2 wherein the proteolytic micrococcus is Micrococcus Cohn, subgroups 1 to 4.
Claim 12
Dependent Claim
24 words
A method in accordance with claim 10 wherein the flavoring microorganism is a homofermentative lactobacillus selected from L. lactis, L. bulgaricus, and L. caseii.
Claim 13
Dependent Claim
76 words
In a method for the manufacture of process cheese wherein a mixture of aged American-type cheese having a conventional American cheese flavor and unaged cheese having minimal American cheese flavor is mixed with emulsifiers, heated to form a homogeneous molten cheese mass and cooled, the improvement comprising replacing at least about 5 percent of said cheeses with a cured natural American cheese product having intensified American cheese flavor components produced by the method of claim 1.
Claim 14
Dependent Claim
31 words
A method in accordance with claim 12 wherein the source of proteolytic enzyme is selected from papain and microbial proteases derived from A. oryzae, A. flavus-oryzae, B. subtilus and mixtures thereof.
Claim 15
Dependent Claim
28 words
A method in accordance with claim 13 wherein the milk source from which said cheese product is made is inoculated with a proteolytic micrococcus and a flavoring microorganism.
Claim 16
Dependent Claim
26 words
A method in accordance with claim 14 wherein said cheese product has a proteolytic micrococcus and a flavoring microorganism added to the curd prior to curing.
Claim 17
Dependent Claim
19 words
A natural American-type cheese product having highly intensified American cheese flavor components produced by the method of claim 1.
Claim 18
Dependent Claim
40 words
A natural American-type cheese product having highly intensified American cheese flavor components in accordance with claim 16 wherein the source of proteolytic enzyme is selected from papain and proteases derived from A. oryzae, A. flavus-oryzae, B. subtilus, and mixtures thereof.
Claim 19
Dependent Claim
34 words
A natural American-type cheese product having highly intensified American cheese flavor components in accordance with claim 17 having a source of proteolytic micrococcus and a flavoring microorganism incorporated in the curd prior to curing.
