Spray-drying microencapsulation of ascorbic acid: impact of varying loading content on physicochemical properties of microencapsulated powders.

Background: There is increased interest in the food, pharmaceutical and cosmetic industries in using ascorbic acid as an important component in the human diet for health support and disease prevention. However, its use as an ingredient is limited by its high instability and sensitivity to environmental conditions. Microencapsulation technology has been proposed to increase the stability of ascorbic acid.
