Rheology and Stability of Citral/Sugar Microemulsions

摘要

Carrier systems are usually formulated by combining several components. In the case of citral emulsions that will be spray dried, a combination of ingredients is necessary to contribute to emulsion formation, aroma retention, and improve stability. Emulsion stability was strongly influenced by continuous phase viscosity, affecting both droplet diameter and destabilization processes. In this sense, MD was a key ingredient to provide more stable emulsions. The disaccharides alone promoted more instability; however, their inclusion must be considered in order to achieve better flavor retention upon spray drying.
