Abstract
Abstract A hard candy having excellent shelf stability may contain at least 80% by weight fructose, such as in the form of high fructose corn syrup, and optionally, small amounts of dextrin. A method for preparing the above high fructose hard candy is also provided which employs vacuum removal of moisture to avoid degradation and discoloration and impart long shelf-life stability to the hard candy.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
42 words
A substantially gas-free high fructose hard candy consisting essentially of from about 80 to about 98% fructose which candy is dry and shelf-stable, and further including from about 1 to about 20% by weight dextrin, inulin, a cellulose gum or mixtures thereof.
Claim 2
Dependent Claim
42 words
A substantially gas-free high fructose hard candy consisting essentially of from about 80 to about 98% fructose which candy is dry and shelf-stable, and further including from about 1 to about 20% by weight dextrin, inulin, a cellulose gum or mixtures thereof.
Claim 3
Dependent Claim
29 words
The candy as defined in claim 1 wherein dextrin is present in an amount within the range of from about 1 to about 20% by weight of the candy.
Claim 4
Dependent Claim
13 words
The candy as defined in claim 1 containing fructose as the only sugar.
Claim 5
Dependent Claim
15 words
The candy as defined in claim 1 containing a sugar in addition to said fructose.
Claim 6
Dependent Claim
59 words
A method for preparing the hard candy as defined in claim 1 which comprises forming an aqueous solution of fructose and dextrin, inulin or cellulose gum, heating the solution to from about 260° to about 300° F., applying a vacuum of from about 5 to about 30 inches Hg, to remove moisture, and cooling to form the hard candy.
Claim 7
Dependent Claim
14 words

Claim 8
Dependent Claim
16 words
The method as defined in claim 5 wherein the initial fructose is high fructose corn syrup.
Claim 9
Dependent Claim
22 words
The method as defined in claim 6 wherein an aqueous solution of dextrin is mixed with crystalline fructose to form said solution.
Claim 10
Dependent Claim
20 words
The method as defined in claim 7 wherein high fructose corn syrup is mixed with dextrin to form said solution.
