Abstract
Abstract The present invention is a new crystalline sugar product and method of making same which includes forming a bi-dimensionally stabilized sugar crystalline frame from an outer portion of an amorphous shearform sugar mass, and, subsequently, converting the remaining portion of the mass to a substantially completely crystalline structure which retains the cross-sectional dimension of the sugar crystalline frame. The present invention also includes co-crystallizing an additive, especially a bio-affecting additive, during the process to provide a co-crystallized product. The structure of the crystallized product can also be loaded with a non-solvent liquid by force of capillary action in the space created within the structure during the conversion from amorphous mass to crystalline structure.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
112 words
A sugar product comprising: bi-dimensionally stabilized crystalline sugar produced by i) forming a sugar crystalline frame from an outer portion of an amorphous shearform sugar mass in the presence of a controlled amount of water which initiates crystallization of amorphous sugar, and ii) subsequently converting the remaining portion of said mass to a substantially completely crystalline structure by continued controlled contacting of said shearform amorphous sugar mass having a shell which has a cross-sectional dimension. said shell formed thereon with water in a substantially non-aqueous gaseous environment rate and in an amount sufficient to maintain said shell and permit said remaining portion of said mass to crystallize to form said crystalline structure.
Claim 2
Dependent Claim
112 words
A sugar product comprising: bi-dimensionally stabilized crystalline sugar produced by i) forming a sugar crystalline frame from an outer portion of an amorphous shearform sugar mass in the presence of a controlled amount of water which initiates crystallization of amorphous sugar, and ii) subsequently converting the remaining portion of said mass to a substantially completely crystalline structure by continued controlled contacting of said shearform amorphous sugar mass having a shell which has a cross-sectional dimension. said shell formed thereon with water in a substantially non-aqueous gaseous environment rate and in an amount sufficient to maintain said shell and permit said remaining portion of said mass to crystallize to form said crystalline structure.
Claim 3
Dependent Claim
13 words
The sugar product of claim 1 wherein all said product is bi-dimensionally monodispersed.
Claim 4
Dependent Claim
24 words

The sugar product of claim 3 wherein said additive is selected from the group consisting of flavorants, bio-affecting agents, dyes, fragrances, food products, food ingredients, and other compatible agents.
Claim 6
Dependent Claim
13 words
The sugar product of claim 1 wherein said monodispersed stabilized structure is microcrystalline.
Claim 7
Dependent Claim
38 words
The sugar product of claim 1 wherein said amorphous shearform product is substantially rod shaped, said two dimensions lying in a cross-sectional plane of said rod and said one dimension extending along the linear axis of said rod.
Claim 8
Dependent Claim

Claim 12
Dependent Claim
51 words
The sugar product of claim 1 wherein said forming comprises: controlledly contacting said shearform amorphous sugar with water in a nonaqueous fluid environment at a rate and in an amount sufficient to provide said frame and maintain said shell wherein said converting comprises subsequently promoting progressive crystallization to form said structure.
Claim 13
Dependent Claim
62 words
The sugar product of claim 1 wherein said forming comprises: controlledly adding heat to said shearform sugar mass in a substantially nonaqueous gaseous environment which has a relative humidity (r.h.) sufficient to transform amorphous sugar on the outer surface of said mass to a shell having said bi-dimensional stability and wherein said converting comprises subsequently promoting progressive crystallization to form said structure.
Claim 14
Dependent Claim
25 words
The sugar product of claim 1 which further comprises a non-solvent liquid carried in space created within said new crystalline sugar product by said converting.
Claim 15
Dependent Claim
14 words
