Claim 3
Dependent Claim
23 words
The liquid xylitol composition of claim 1, wherein said dry solids are comprised of 60-80% xylitol and 20-40% non-xylitol monomeric or dimeric polyols.
Claim 4
Dependent Claim
25 words
The liquid xylitol composition of claim 1, wherein said non-xylitol polyols are selected from the group consisting of maltitol, sorbitol, mannitol, glycerol and mixtures thereof.
Claim 5
Dependent Claim
18 words
The liquid xylitol composition of claim 3 wherein the source of said non-xylitol polyols is pure crystalline solutions.
Claim 6
Dependent Claim
17 words
The liquid xylitol composition of claim 3 wherein the source of said non-xylitol polyols is polyol syrups.
Claim 7
Dependent Claim
19 words
The liquid xylitol composition of claim 1, wherein said xylitol is derived from run-off from a xylitol crystallization process.
Claim 8
Dependent Claim
52 words
The liquid xylitol composition of claim 6, wherein said xylitol and a portion of said non-xylitol polyols are derived from runoff from a xylitol crystallization process, said runoff comprising, on a dry solids basis, approximately 70-98% xylitol, about 1-10% sorbitol, about 0-5% galactitol, about 0-5% arabinitol and rhamnitol and about 0-2% mannitol.
Claim 9
Dependent Claim
13 words
The liquid xylitol composition of claim 7, wherein said runoff comprises 80-90% xylitol.
Claim 10
Dependent Claim
27 words
The liquid xylitol composition of claim 6 wherein said dry solids content is 70% and said dry solids are comprised of about 50 to about 60% xylitol.
Claim 11
Independent Claim
86 words
A method for producing non-crystallizing liquid xylitol comprising collecting run-off after the second crystallization stage of a xylitol crystallization process, said runoff comprising, on a dry solids basis, approximately 70-98% xylitol, about 1-10% sorbitol, about 0-5% galactitol, about 0-5% arabinitol and rhamnitol and about 0-2% mannitol; adding to said run-off a polyol solution to create a 50-80% dry solids xylitol composition, such that 50-90% of the dry solids of said composition are comprised of xylitol and 10-50% of the dry solids are comprised of non-xylitol polyols.
Claim 12
Independent Claim
86 words
A method for producing non-crystallizing liquid xylitol comprising collecting run-off after the second crystallization stage of a xylitol crystallization process, said runoff comprising, on a dry solids basis, approximately 70-98% xylitol, about 1-10% sorbitol, about 0-5% galactitol, about 0-5% arabinitol and rhamnitol and about 0-2% mannitol; adding to said run-off a polyol solution to create a 50-80% dry solids xylitol composition, such that 50-90% of the dry solids of said composition are comprised of xylitol and 10-50% of the dry solids are comprised of non-xylitol polyols.
Claim 13
Dependent Claim
13 words

A method according to claim 12 wherein said non-xylitol polyols are added in the form of solutions prepared by dissolving the crystalline form of one or more of said polyols in a solvent.
Claim 17
Independent Claim
52 words
A method for producing a non-crystallizing liquid xylitol composition comprising adding to a xylitol solution one or more non-xylitol polyols to create a composition having 60-80% dry solids, wherein 50-90% of the dry solids are comprised of xylitol and 10-50% of the dry solids are comprised of one or more non-xylitol polyols.
Claim 18
Independent Claim
52 words
A method for producing a non-crystallizing liquid xylitol composition comprising adding to a xylitol solution one or more non-xylitol polyols to create a composition having 60-80% dry solids, wherein 50-90% of the dry solids are comprised of xylitol and 10-50% of the dry solids are comprised of one or more non-xylitol polyols.
Claim 19
Dependent Claim
