Abstract
Abstract Cheese is prepared from milk which has been delactosed and dewatered by a process involving standardizing fluid whole milk, molecular sieving the standardized milk to substantially separate and remove lactose and water soluble minerals from the milk to render the milk substantially sugar-free, at least partially dewatering the substantially sugar-free milk to substantially the water content desired in a finished cheese, adding a curd foaming agent to produce curd, subjecting the resultant curd to conventional manipulation without substantial syneresis to produce cheese, and molding the resulting cheese to form.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
112 words
A process for manufacturing a substantially sugar-free cheese food comprising the steps of: A. standardizing fluid whole milk to secure the desired ratio of fat to other milk solids, B. molecular sieving the resulting milk product to substantially separate and remove lactose and water soluble minerals from the milk to render the milk substantially sugar-free, C. at least partially dewatering the resulting substantially sugar-free milk colloid to substantially the water content desired in the finished cheese food, D. adding a curd-forming agent, E. subjecting the resulting curd in the cheese-making mixture to conventional manipulation to promote proper curd formation, and without any substantial syneresis, and F. molding the resulting cheese to form.
Claim 2
Dependent Claim
112 words
A process for manufacturing a substantially sugar-free cheese food comprising the steps of: A. standardizing fluid whole milk to secure the desired ratio of fat to other milk solids, B. molecular sieving the resulting milk product to substantially separate and remove lactose and water soluble minerals from the milk to render the milk substantially sugar-free, C. at least partially dewatering the resulting substantially sugar-free milk colloid to substantially the water content desired in the finished cheese food, D. adding a curd-forming agent, E. subjecting the resulting curd in the cheese-making mixture to conventional manipulation to promote proper curd formation, and without any substantial syneresis, and F. molding the resulting cheese to form.
Claim 3
Dependent Claim
22 words
A process according to claim 1 further characterized in that said molcular sieving is accomplished by gel filtration of the milk product.
Claim 4
Dependent Claim
27 words
A process according to claim 1 for making a cheese of higher fat content further characterized in that further fat is added to the delactosed milk colloid.
Claim 5
Dependent Claim
30 words
A process according to claim 3 further characterized in that said fat is added to the cheese-making mixture along with said curd-forming agent and blended into the curds as formed.
Claim 6
Dependent Claim
37 words
A process according to claim 3 further characterized in that said fat is added as a substance selected from the group consisting of cream, milk fat, other edible animal fats and oils and vegetable fats and oils.
Claim 7
Dependent Claim
29 words
A process according to claim 1 further characterized in that salt is added to the cheese-making mixture along with said curd-forming agent and blended into the curds as formed.
Claim 8
Dependent Claim
31 words
A process according to claim 1 further characterized in that a ripening agent is added to the cheese-making mixture along with said curd-forming agent and blended into the curds as formed.
Claim 9
Dependent Claim
16 words
A process according to claim 1 further characterized in that the curd is manipulated by extrusion.
Claim 10
Dependent Claim
16 words
A process according to claim 1 further characterized in that the curd is manipulated by kneading.
Claim 11
Dependent Claim
18 words
A process according to claim 1 further characterized in that additional protein is admixed with the cheese-making mixture.
