Sweeteners microcapsulation and their effect on the low-calorie sweet dishes flavor

The correlation between the health of the population and the economic growth of the state is obvious, with the greatest concern being the spread of diabetes. The purpose of research is to study microcapsulation of sweeteners and analyze their effect on the flavor of low-calorie sweet dishes (jelly). Microcapsules of the sweeteners aspartame, sucralose, stevioside were obtained by adding a dropwise solution of sodium alginate and a sweetener with stirring at a speed of 2000-3000 rpm into a 2 % solution of calcium lactate at a speed of 0.5 cm3/min. All microcapsules had a spherical shape, the size of microcapsules was from 150.2 to 250.1 µm. Microcapsules of aspartame, sucralose, stevioside were evaluated by tasters from 4.66 to 4.8 points. The duration of the onset of the sweet taste (attack) and the duration of the aftertaste were evaluated, also stating extraneous aftertastes. Sucralose microcapsules have the least amount of unpleasant aftertaste (bitter, metallic), the highest rate of occurrence and duration of aftertaste compared to aspartame and stevioside. 7 samples of cranberry jelly were prepared: on sugar; with the replacement of sugar with microcapsules of sweeteners; with the replacement of sugar with nonencapsulated sucralose, aspartame, stevioside. Organoleptic evaluation showed that the inclusion of microcapsules reduces the transparency of the jelly, it takes more time to chew jelly with microcapsules. At the same time, the appearance of a sweet taste is slower, and the aftertaste is longer, which gives a feeling of a more pronounced sweet taste due to the fact that the molecules are gradually chewed and the sweet taste grows. Thus, the use of microcapsules allows the gradual release of the sweet agent, which generally improves its flavor, including aftertaste. The presented technology of microcapsulation of sweeteners makes it possible to control the release of sweet taste, hide the taste deficiencies of the sweetener, increase the duration of the aftertaste, and also increase the persistence of the sweet taste of the aspartame sweetener due to the protective outer shell of the capsule.
