Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
130 words
A process for preparing sweetened raisins having a low water activity relative to their moisture content, which process comprises: (a) bathing raisins having a moisture content of less than about 8 weight percent in an aqueous sugar solution having about 70 to 95 weight percent sugar, at least about 90 weight percent of which is fructose, at a temperature of about 5° to 110° C. for a sufficient length of time to increase the fructose/glucose weight ratio of the raisins by at least 15 percent and to increase the moisture content by at least 50 percent while maintaining the water activity of the raisins at less than about 0.5; and (b) separating the sweetened raisins having a low water activity relative to their moisture content from the aqueous sugar solution.
Claim 2
Dependent Claim
130 words
A process for preparing sweetened raisins having a low water activity relative to their moisture content, which process comprises: (a) bathing raisins having a moisture content of less than about 8 weight percent in an aqueous sugar solution having about 70 to 95 weight percent sugar, at least about 90 weight percent of which is fructose, at a temperature of about 5° to 110° C. for a sufficient length of time to increase the fructose/glucose weight ratio of the raisins by at least 15 percent and to increase the moisture content by at least 50 percent while maintaining the water activity of the raisins at less than about 0.5; and (b) separating the sweetened raisins having a low water activity relative to their moisture content from the aqueous sugar solution.
Claim 3
Dependent Claim
17 words
The process of claim 1 wherein the sugar in the aqueous sugar solution consists essentially of fructose.
Claim 4
Dependent Claim
19 words
The process of claim 2 wherein the bathing is conducted at a temperature of about 20° to 80° C.
Claim 5
Dependent Claim
27 words
The process of claim 3 wherein the raisins have a moisture content of less than about 6 weight percent prior to bathing in the aqueous sugar solution.
Claim 6
Dependent Claim
96 words
A process for preparing sweetened fruit having a low water activity relative to its moisture content, which process comprises: (a) obtaining a fruit; (b) drying the fruit to reduce its moisture content by at least about 50 percent; (c) bathing the dry fruit in an aqueous sugar solution having about 70 to 95 weight percent sugar, at least about 75 weight percent of which is fructose, at a temperature of about 5° to 110° C.; and (d) separating the sweetened fruit having a low water activity relative to its moisture content from the aqueous sugar solution.
Claim 7
Dependent Claim
96 words
A process for preparing sweetened fruit having a low water activity relative to its moisture content, which process comprises: (a) obtaining a fruit; (b) drying the fruit to reduce its moisture content by at least about 50 percent; (c) bathing the dry fruit in an aqueous sugar solution having about 70 to 95 weight percent sugar, at least about 75 weight percent of which is fructose, at a temperature of about 5° to 110° C.; and (d) separating the sweetened fruit having a low water activity relative to its moisture content from the aqueous sugar solution.
Claim 8
Dependent Claim
17 words
The process of claim 5 wherein the sugar in the aqueous sugar solution consists essentially of fructose.
Claim 9
Dependent Claim
19 words

The process of claim 5 wherein the fruit is selected from the group consisting of bananas, raisins, and strawberries.
Claim 12
Dependent Claim
37 words
An improved process for preparing sweetened fruit by bathing a fruit in an aqueous sugar solution, wherein the improvement comprises drying the fruit prior to bathing to reduce its moisture content by at least about 50 percent.
Claim 13
Dependent Claim
37 words
An improved process for preparing sweetened fruit by bathing a fruit in an aqueous sugar solution, wherein the improvement comprises drying the fruit prior to bathing to reduce its moisture content by at least about 50 percent.
