Executives ... FYI.

To make the most of expensive and sensitive ingredients in foods as well as pharmaceuticals, it is important that ingredient stability is high and that release of the active component occurs within a desired profile in the product. Spray-drying can be used for encapsulation and powder generation in one step by utilizing different phenomena that occur during drying. By controlling formulation and processing, it is possible to improve stability and release profiles. A recently developed concept involves the application of aqueous two-phase systems for drying and encapsulating water-soluble materials and probiotic bacteria. During spray-drying, surface-active components interact with the droplet surface, and coat the powder surface according to their adsorption efficiency. By understanding these events, formulation and drying conditions can be designed to achieve the best coating and encapsulation results.
