Abstract
Abstract Sucralose (4-chloro-4-deoxy- alpha -D-galactopyranosyl 1,6-dichloro-1,6-dideoxy- beta -D-fructofuranoside) is thermally stabilized by co-crystallization with a nitrogenous base, for example niacinamide or an amino acid.

Claim 1
Independent Claim
21 words
Sucralose (4-chloro-4-deoxy-α-D-galactopyranosyl 1,6-dichloro-1,6-dideoxy-β-D-fructofuranoside) co-crystallized with an up to 100° C. color stabilizing amount of an acceptable food additive, co-crystallizable nitrogenous base.
Claim 2
Dependent Claim
21 words
Sucralose (4-chloro-4-deoxy-α-D-galactopyranosyl 1,6-dichloro-1,6-dideoxy-β-D-fructofuranoside) co-crystallized with an up to 100° C. color stabilizing amount of an acceptable food additive, co-crystallizable nitrogenous base.
Claim 3
Dependent Claim
15 words
Sucralose according to claim 1 co-crystallized with an aliphatic or cyclic secondary or tertiary amine.
Claim 4
Dependent Claim
10 words
Sucralose according to claim 1 co-crystallised with an amino acid.
Claim 5
Dependent Claim
16 words

Sucralose according to claim 5 containing 0.3 to 0.9% by weight of niacinamide.
Claim 8
Independent Claim
44 words
A method of improving the color stability up to 100° C. of sucralose by crystallizing it from a co-solution of sucralose and an acceptable food additive, co-crystallizable nitrogenous base to obtain a co-crystallized product containing sucralose and a color stabilizing amount of said base.
Claim 9
Independent Claim
44 words
A method of improving the color stability up to 100° C. of sucralose by crystallizing it from a co-solution of sucralose and an acceptable food additive, co-crystallizable nitrogenous base to obtain a co-crystallized product containing sucralose and a color stabilizing amount of said base.

Claim 13
Dependent Claim
12 words
A method according to claim 10, in which the base is niacinamide.
Claim 14
Dependent Claim
18 words
