The development of special formulated forms of vitamin and carotenoid dry powders solved most of the technical problems encountered in handling the original pure crystalline or oily compounds. Various procedures to obtain stabilized products have been introduced on an industrial scale for feed , food and pharmaceutical purposes. Proven modes of manufacture of formulated dry powders includes the numerous spraying processes for emulsions, dispersions or solutions, and the production of adsorbates of fat-based products.
The objective of this paper is to provide an overview of stabilized vitamin and carotenoid dry powders. This contribution is intended to demonstrate the usefulness of microscopy in characterizing pure and formulated vitamins and carotenoids. Scanning electron microscopy is considered to be a reliable and fast method for analyzing various parameters of these compounds, such as , morphology , particle size distribution , and formation system of emulsion droplets.
