Development of the desserts based on non-traditional vegetable raw materials

Nowadays, the problem of healthy eating is acute. Most consumers prefer organic foods, dishes based on natural vegetables and fruits, and healthy nutrition. Thus, reducing calories content and increasing the nutritional value of sweet dishes is a promising area for the research. Therefore, the object of this study is the technology of whipped sweet «sambuk»-type dishes. To create the new desserts, non-traditional vegetable raw materials, namely physalis puree and banana puree, were chosen. Physico-chemical, mathematical, and dessert quality analysis methods were used in the study. One of the most problematic tasks in the technology of whipped desserts is the stabilization of the foam structure. Therefore, the inclusion of physalis puree and banana puree in the recipe affects not only the organoleptic properties, but also improves the physical and chemical parameters of the dish. In particular, the aggregate stability coefficient of the foam increases to 4.33 in the samples with banana puree and to 3.48 in the samples with physalis puree, which is 2 and 1.66 times higher than the same indicator for control sample. The specific volume also has a noticeable improvement (it is 1.5 times higher in samples with physalis puree and 1.16 times higher in samples with banana puree comparing to control). During the study the effect of selected raw materials on the dry matter content in new desserts was determined (it ranges from 36.5 % to 41.3 5 % in samples with physalis puree and from 23.2 % to 27.8 % in the case of adding banana puree) . The acidity of the model samples ranges from 4.8 to 4.61 pH in desserts with physalis puree, and from 5.53 to 5.41 pH in desserts with banana puree. Based on the expert assessment, the value of the sample quality criteria was determined. Conclusions are made on the expediency of non-traditional raw materials using in the preparation of whipped desserts
