Vitamin D(cholecalciferol)plays a crucial role in various physiological processes. However, vitamin D 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 plasmolyzedSaccharomyces 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. 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.
维生素 D（胆钙化醇）在各种生理过程中起着至关重要的作用。然而，维生素 D 缺乏是一个影响数百万人的主要公共卫生问题。因此，开发确保这种重要维生素用于食品补充和强化的保护和稳定性的有效策略非常重要。这项工作旨在使用生物吸附法将完整和质壁分离的酿酒酵母生物质与胆钙化醇一起浸渍，然后进行喷雾干燥，以根据形态、平均粒径、Zeta 电位、水分、水分活度、FT-IR 以及在干燥和储存过程中封装维生素的稳定性来对获得的材料进行表征。质壁分离被证明是一种提高生物吸附效率、喷雾干燥过程中保留率和维生素 D 稳定性的有效方法。此外，该过程促进了细胞尺寸的增加，这有利于系统的分散稳定性，如 Zeta 电位值所示。这些结果有助于了解一种符合环保实践的新型维生素递送方法。
