Abstract

Vitamin D 3 (cholecalciferol) plays a crucial role in various physiological processes. However, vitamin D 3 deficiency is a major public health problem affecting millions of people. Therefore, it is important to develop effective strategies that ensure the protection and stability of this important vitamin for food supplementation and fortification. This work aimed to impregnate intact and plasmolyzed Saccharomyces pastorianus brewer 's yeast biomass with cholecalciferol using a biosorption process followed by spray drying to characterize the obtained material in terms of morphology, average particle size, zeta potential, moisture, water activity, FT-IR, and the stability of the encapsulated vitamin during the drying and storage process. Plasmolysis proved to be an effective method for improving the biosorption efficiency, retention during spray drying, and stability of vitamin D 3 . In addition, this process promoted an increase in cell size, which favored the dispersion stability of the system, as evidenced by the zeta potential values. These results contribute to the understanding of a new method for delivering this vitamin that conforms to environmentally conscious practices. (AU)
