Low calorie dry sweetener composition
Pulverulent free-flowing water-soluble low calorie sweetener compositions having the general appearance of sucrose are produced by preparing a strong aqueous solution or slurry of an aspartyl-phenylalanine methyl ester sweetener at a relatively low temperature, admixing therewith a heated aqueous starch hydrolysate having a D.E. of zero to 20, and promptly thereafter, feeding the mixture to the preheater of a spray drier and thereupon spray drying said mixture to provide an expanded dry pulverulent composition containing a low moisture content.

Claims
1. A method of preparing a dry pulverulent low calorie sweetener composition containing an aspartyl dipeptide lower alkyl ester of the formula ##STR3## wherein X is selected from the group of radicals consisting of ##STR4## and
- a. preparing an aqueous starch hydrolysate solution having a D.E. up to 20 and having a temperature of about 30.degree. to about 80.degree. C,
- b. preparing a substantially concentrated aqueous solution or slurry of said ester having a temperature in the range up to about 40.degree. C,
- c. admixing a minor proportion of the b. solution or slurry with a major proportion of the a. solution, and
- d. promptly drying the c. mixture to provide a dry pulverulent composition containing from 0.5 to 10 percent, by weight, of said ester, and not more than about 4 percent moisture.
2. A method of preparing a dry pulverulent low calorie sweetener composition containing an aspartyl dipeptide lower alkyl ester of the formula ##STR5## wherein X is selected from the group of radicals consisting of ##STR6## and
- a. preparing an aqueous starch hydrolysate having a D.E. up to 20 and having a temperature of about 30.degree. to about 80.degree. C,
- b. preparing a substantially concentrated aqueous solution or slurry of said ester having a temperature not exceeding about 40.degree. C,
- c. admixing a minor proportion of the b. solution or slurry with a major proportion of the a. solution, said minor proportion being in an amount sufficient to provide in the final product from 0.5 to 10 percent, by weight,
- d. promptly feeding the c. mixture to a preheater of a spray dryer and thereupon spray drying said c. mixture to provide a dry pulverulent composition containing not more than about 4 percent moisture.
3. The method of claim 2 in which the starch hydrolysate is a sorghum starch hydrolysate having a D.E. in the range up to about 12.
