ABSTRACT
Nanoemulsion system is a colloidal system made up of kinetically stable minute droplets. They overcome the drawbacks related to the conventional emulsion system. The structure and composition of nanoemulsion can be moulded to effectively control and deliver bioactive and nutraceutical compounds. There are a number of potential applications found for the effective delivery of functional foods, nutraceuticals, coloring, flavoring and antimicrobial agents in food industry. These systems can be exploited to develop biodegradable packaging and coating films for the enhancement of the functional and nutritional value along with enhancing the quality, bioavailability and shelf life of the functional foods. This chapter focuses on the history of emulsion system and nutraceutical and functional foods, preparation techniques of nanoemulsions, components of nanoemulsion system, encapsulation of nutraceuticals, flavoring, coloring agents and packaging materials, application of nanoemulsion in food and nutraceutical industry and the current and future prospects of the topic.
