Abstract
Abstract A method of processing fresh cherries which renders them storable, whereby the cherries are immersed in an aqueous storage solution containing an edible bacteriostatic acid and dissolved sugar. Sweetened cherries may be produced by draining stored cherries of this storage solution, and reimmersing them in a syrup prepared by increasing the sugar concentration of the storage solution.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
71 words
A method of processing cherries which comprises collecting cherries in a fresh, uncooked condition, and immersing said fresh, uncooked cherries for storage purposes, without pretreatment with sulfur dioxide or derivatives thereof, in an aqueous storage solution made up of an edible acid and dissolved sugar, the acid in said solution having sufficient concentration to inhibit bacterial growth and the sugar solute in the solution inhibiting osmotically produced change in cherry appearance.
Claim 2
Independent Claim
71 words
A method of processing cherries which comprises collecting cherries in a fresh, uncooked condition, and immersing said fresh, uncooked cherries for storage purposes, without pretreatment with sulfur dioxide or derivatives thereof, in an aqueous storage solution made up of an edible acid and dissolved sugar, the acid in said solution having sufficient concentration to inhibit bacterial growth and the sugar solute in the solution inhibiting osmotically produced change in cherry appearance.
Claim 3
Dependent Claim
29 words
The method of claim 1 wherein the edible acid produces a pH value of less than 4.0 and is selected from the group consisting of citric and phosphoric acid.
Claim 4
Dependent Claim
18 words
The method of claim 1 wherein said storage solution comprises from about 20 to 31 percent sugar solute.
Claim 5
Dependent Claim
16 words
The method of claim 1 wherein an antifungous agent is also included in the storage solution.
Claim 6
Dependent Claim
34 words
The method of claim 1, wherein said cherries, after immersion in said storage solution, are immersed in another solution prepared from the storage solution by increasing the concentration of sugar in said storage solution.
Claim 7
Dependent Claim
27 words
The method of claim 5, wherein said other solution is prepared with the further inclusion of an acid neutralizer which reduces the acidity of the storage solution.
Claim 8
Independent Claim
85 words
A method of processing cherries which comprises storing fresh, uncooked cherries, which have not been treated with sulfur dioxide or derivatives thereof, by immersing them in an aqueous storage solution containing an edible bacteriostatic acid having sufficient concentration to inhibit bacterial growth and sugar effective to inhibit osmotically produced change in cherry, appearance and after storage of the cherries increasing their sugar concentration by immersing them in another solution, derived from said storage solution, prepared by increasing the concentration of sugar in said storage solution.
Claim 9
Independent Claim
85 words
A method of processing cherries which comprises storing fresh, uncooked cherries, which have not been treated with sulfur dioxide or derivatives thereof, by immersing them in an aqueous storage solution containing an edible bacteriostatic acid having sufficient concentration to inhibit bacterial growth and sugar effective to inhibit osmotically produced change in cherry, appearance and after storage of the cherries increasing their sugar concentration by immersing them in another solution, derived from said storage solution, prepared by increasing the concentration of sugar in said storage solution.
Claim 10
Dependent Claim
25 words
The method of claim 7 wherein the immersion in said other solution is done with periodic increase in the sugar concentration of said other solution.
Claim 11
Dependent Claim
21 words
The method of claim 7 wherein the sugar concentration in said other solution is increased periodically through the evaporation of water.
Claim 12
Dependent Claim
8 words
Cherries processed by the method of claim 7.
