Fluidised Bed Microencapsulation of Ascorbic Acid: Effectiveness of Protection under Simulated Tropical Storage Conditions

Abstract

This study investigates the use of microencapsulation by fluidised bed coating for the protection of ascorbic acid during long-term storage under simulated tropical conditions. Microencapsulation materials, loading levels, fluidised bed processing conditions and the results of storage trials were evaluated. Cellets(registered trademark) 350 is a suitable base material, whereas sugar spheres are not suitable due to agglomeration and bed collapse during processing. Sodium alginate provided the best overall performance with low processing losses and high retention of ascorbic acid during storage. The results of this study provide a basis for further research including incorporation of ascorbic acid microcapsules into food matrices using a fluidised bed coating.
