Challenges and solutions to incorporation of nutraceuticals in foods.

Manufacturers often cannot simply add a nutraceutical to a food when formulating functional foods that have acceptable sensory appeal as well as the desired health benefits. The appropriate application of microencapsulation for stabilizing nutraceuticals enables their effective delivery through food. Careful design of the delivery system helps protect sensitive nutraceuticals from the environment and processing stresses encountered during food manufacture, and prevents undesirable interactions of the nutraceutical with components in the food matrix. Microencapsulation technologies overcome hurdles associated with the successful delivery of nutraceuticals in healthy foods if due consideration is given to challenges at all stages throughout the supply chain. This encompasses stabilizing and protecting nutraceuticals from degradation in ingredient formats, during processing, in the final food product, and during intestinal transit until they are released at the desired site in the gastrointestinal tract to impart their targeted health effects.
