Multiple Emulsions for Enhanced Delivery of Vitamins and Iron Micronutrients and Their Application for Food Fortification

Vitamins and iron are micronutrients that are of paramount importance in human nutrition. High prevalence of the diseases caused by micronutrient deficiency accentuates the need to consider strategies for the fortification of food products with these micronutrients to enhance their nutritional properties for addressing micronutrient deficiencies. During recent years, specific attention has been devoted to the development and implementation of different processing alternatives for food fortification. Multiple emulsion systems, particularly double emulsions (DEs), show potential for delivery of micronutrients, enabling their controlled delivery and enhanced bioaccessibility during digestion. As micronutrient deficiencies are a major public health concern, this review article aims to highlight recent advances in the application of multiple emulsions for enhanced delivery of vitamins and iron with the aim to provide insights to food scientists and nutritionists considering strategies for food fortification.
