Prospects in the process of fortification of bakery products with vitamin D
In the introduction it is pointed out the subject of this research - vitamin D. The main issues related to it are following: the structure of ergo- and cholecalciferol, vitamin D deficiency and its consequences, the D-vitamin status indicator, 25(OH)D biomarker levels and their significance in the human body. The purpose of research is the study of new approaches in the process of enriching bread with vitamin D. In the main part it is made an overview of the scientific literature concerning main sources of vitamin D and it is substantiated the need to correct the D-vitamin status of the population of the Republic of Belarus through the fortification of food. It is presented the model of fortification of bread and bakery products with cholecalciferol, reflecting the level of provision of population with vitamin D, seasonal fluctuations in the level of 25(OH)D due to the varying degrees of insolation, consumption of dietary supplements, the frequency of consumption of fortified product, and the expenditure of other sources of calciferols. It is constructed a diagram that represents the levels of enrichment of bakery products to increase the demand for vitamin D to the recommended level. The optimal applications of the enriching component, which help to obtain a product with functional properties with specified properties, are identified. The trial baking of samples of rye and rye-wheat bread enriched with vitamin D is carried out. It is presented a normative documentation in the section “Materials and methods of research”. Specific properties of the baked bread samples are established. The results of the evaluation of physicochemical and organoleptic quality indices of finished products are given. The practical significance of the work is revealed. In the conclusion the need to create a functional method of mass consumption, enriched with vitamin D, and the formation of specific prerequisites for replenishing the vitamin D deficiency in the average daily diet of the population of the republic are indicated.
