Application of Starch Hydrolysate to Improve the Physical Properties of New Low Calorie Sweetener Composition Including Aspartame

Abstract

The possibility of application of starch hydrolysate was studied to improve the storage stability and physical property of low calorie sweetener composition including aspartame for yogurt. The effect of starch hydrolysate on the storage stability was determined by the quick accelerated storage test. Codrying of aspartame with starch hydrolysate was tested to improve the solubility of aspartame based on factorial experimental design. Application of starch hydrolysate with low dextrose equivalent (DE) and tertiary calcium phosphate improved the storage stability of low calorie sweetener using aspartame. Starch hydrolysate with the lower content of monosaccharide and disaccharide had excellent improvement effect on storagestability of this newly developed sweetener compound. The optimum spray drying condition which satisfied good solubility and bulkiness was established. The reason why the codrying of aspartame with starch hydrolysate improved the solubility of aspartame was discussed. Codried compound of aspartame and starch hydrolysate, prepared according to optimum spray drying condition, showed ag ood solubility and anappropriate bulk density. And this powder blended low calorie sweetener composition with fruit powder has undergone no significant deterioration after 2 years ambient storage.
