Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
110 words
A process for infusing fruit with sugar solutes comprising: (a) suspending the fruit in a heated aqueous syrup bath which is circulated at about 35-45 gal./min., said syrup initially incorporating about 65-75 percent dissolved sugar solutes, said sugar solutes being comprised of about 35 to about 100 percent fructose; (b) inhibiting dilution of the bath caused by exfusing fruit water by introducing a concentrated sugar solution into the bath and withdrawing substantially equal amounts of diluted syrup at a rate of about 2-9 gal./min. so as to stabilize the bath solutes concentration; (c) concentrating the withdrawn, diluted syrup by evaporation; and (d) returning the concentrated syrup to the infusion bath.
Claim 2
Dependent Claim
110 words
A process for infusing fruit with sugar solutes comprising: (a) suspending the fruit in a heated aqueous syrup bath which is circulated at about 35-45 gal./min., said syrup initially incorporating about 65-75 percent dissolved sugar solutes, said sugar solutes being comprised of about 35 to about 100 percent fructose; (b) inhibiting dilution of the bath caused by exfusing fruit water by introducing a concentrated sugar solution into the bath and withdrawing substantially equal amounts of diluted syrup at a rate of about 2-9 gal./min. so as to stabilize the bath solutes concentration; (c) concentrating the withdrawn, diluted syrup by evaporation; and (d) returning the concentrated syrup to the infusion bath.
Claim 3
Dependent Claim
29 words
The process of claim 1 wherein the bath dilution is inhibited by continuously introducing the concentrated sugar solution into the bath while simultaneously withdrawing equal amounts of diluted syrup.
Claim 4
Dependent Claim
26 words
The process of claim 1 wherein said evaporation is accomplished by means of a flash evaporation process which also isolates a portion of the fruit essence.
Claim 5
Dependent Claim
34 words
The process of claim 1 wherein the fruit infused is selected from the group consisting of strawberries, peaches, grapes, apples, raisins, cherries, bananas, papayas, blueberries, mellons, pineapple, kiwi, soursop, raspberries, mango, plums and loganberries.
Claim 6
Dependent Claim
19 words
The process of claim 4 wherein the fruit is infused to a final solutes content of about from 35-50%.
Claim 7
Dependent Claim
18 words
The process of claim 5 wherein the fruit is infused to a final solutes content of about 40-45%.
