Abstract
One embodiment of the present invention provides a sweetener composition, which includes a mixture of N-{N-(3,3-dimethylbutyl)-L-&agr;-aspartyl}-L-phenylalanine 1-methyl ester, and Acesulfame K, wherein a ratio of the Acesulfame K to a total amount of the N-{N-(3,3-dimethylbutyl)-L-&agr;-aspartyl}-L-phenylalanine 1-methyl ester and the Acesulfame K is in the range of 10 to 97% by weight, methods of making and of using. Another embodiment of the present invention provides a method for preparing a sweetener composition, which includes drying an A-type crystal of N-{N-(3,3-dimethylbutyl)-L-&agr;-aspartyl}-L-phenylalanine 1-methyl ester to obtain a C-type crystal of N-{N-(3,3-dimethylbutyl)-L-&agr;-aspartyl}-L-phenylalanine 1-methyl ester. Another embodiment of the present invention provides a method for producing a sweetener, which includes admixing N-{N-(3,3-dimethylbutyl)-L-&agr;-aspartyl}-L-phenylalanine 1-methyl ester with Acesulfame K, wherein a ratio of the Acesulfame K to a total amount of the N-{N-(3,3-dimethylbutyl)-L-&agr;-aspartyl}-L-phenylalanine 1-methyl ester and the Acesulfame K is in the range of 10 to 97% by weight. Another embodiment of the present invention provides a method for improving the dissolution rate of N-{N-(3,3-dimethylbutyl)-L-&agr;-aspartyl}-L-phenylalanine 1-methyl ester, which includes, prior to dissolving the N-{N-(3,3 -dimethylbutyl)-L-&agr;-aspartyl}-L-phenylalanine 1-methyl ester, admixing the N-{N-(3,3-dimethylbutyl)-L-&agr;-aspartyl}-L-phenylalanine 1-methyl ester with Acesulfame K, wherein a ratio of the Acesulfame K to a total amount of the N-{N-(3,3-dimethylbutyl)-L-&agr;-aspartyl}-L-phenylalanine 1-methyl ester and the Acesulfame K is in the range of 10 to 97% by weight.
