Abstract
Abstract The cloud stability of citrus juice beverages and beverage bases is improved by subjecting pasteurized concentrated or single strength citrus juice to at least one enzyme having protease activity. The further step of pretreating the starting material mechanically or enzymatically to make it more accessible to protease activity prior to or simultaneously with treatment with at least one enzyme having protease activity is also within the invention.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
70 words
A process for preparing citrus juice products for use in soft drinks and other beverages, which comprises the step of treating juice selected from the group consisting of pasteurized concentrated citrus juice and pasteurized single strength citrus juice with one or more protease enzymes for a time and under conditions sufficient to improve cloud stability when the juice is subsequently employed in soft drinks and other citrus juice containing beverages.
Claim 2
Dependent Claim
70 words
A process for preparing citrus juice products for use in soft drinks and other beverages, which comprises the step of treating juice selected from the group consisting of pasteurized concentrated citrus juice and pasteurized single strength citrus juice with one or more protease enzymes for a time and under conditions sufficient to improve cloud stability when the juice is subsequently employed in soft drinks and other citrus juice containing beverages.
Claim 3
Dependent Claim
31 words
A process according to claim 1, which comprises the step of treating the juice for at least one minute with at least one protease enzyme at a temperature of 30°-85° C.
Claim 4
Dependent Claim
22 words
A process according to claim 2, wherein the protease activity of the enzyme is 0.001-20 Anson Units per kg single strength juice.
Claim 5
Dependent Claim
32 words
A process according to claim 1, wherein prior to or simultaneously with the enzyme treatment, the juice is mechanically or enzymatically pretreated to render the citrus juice more responsive to protease activity.
Claim 6
Dependent Claim
15 words
A process according to claim 4, wherein the juice is pretreated with cellulase or hemicellulase.
Claim 7
Dependent Claim
29 words
A process according to claim 5, wherein cellulase or hemiceullulase is used at a concentration of at most 30,000 cellulase units and/or hemicellulase units per kg single strength juice.
Claim 8
Dependent Claim
13 words
A process according to claim 4, wherein homogenization is used as the pretreatment.
Claim 9
Dependent Claim
75 words
A process for preparing citrus juice containing soft drinks which comprises the step of treating juice selected from the group consisting of pasteurized concentrated citrus juice and pasteurized single strength citrus juice with one or more protease enzymes for a time and under conditions sufficient to improve cloud stability when the juice is subsequently employed in a soft drink and using up to about 60% of the enzyme-treated citrus juice to prepare a soft drink.
Claim 10
Dependent Claim
75 words
A process for preparing citrus juice containing soft drinks which comprises the step of treating juice selected from the group consisting of pasteurized concentrated citrus juice and pasteurized single strength citrus juice with one or more protease enzymes for a time and under conditions sufficient to improve cloud stability when the juice is subsequently employed in a soft drink and using up to about 60% of the enzyme-treated citrus juice to prepare a soft drink.
Claim 11
Dependent Claim
21 words
A process according to claim 8, wherein the enzyme treatment and the addition to the soft drink are carried out simultaneously.
Claim 12
Dependent Claim
16 words
A citrus juice containing soft drink prepared according to the process of claims 8 or 9.
Claim 13
Dependent Claim
20 words
A citrus juice product for use in soft drinks and other beverages prepared according to the process of claim 1.
Claim 14
Dependent Claim
15 words
A process according to claim 1 or 8, wherein the citrus juice is orange juice.
