ABSTRACT
Numerous nanotechnology-based initiatives for the delivery of nutraceuticals begun in early 2000. US market growth for delivery of nanocoatings on food beverages goes around $1 billion and is expected to increase up to $20 billion in the upcoming years. This is one of the fastest-growing industries after pharmaceuticals. Use of polymer or surfactant for encapsulation or enhancing the interaction with lipids, protein, or polysaccharides within formulation increases the stability of nutraceuticals. The applicability of polymers or surfactants to form a nanostructured material opens up new avenues in functional nanoparticulate delivery. Applicability of functional formulation enhances the delivery of nutraceuticals to desired site of absorption or action. The nanofabricated polymeric systems could engross the bioavailability of multiple nutraceuticals within formulations and dignify the underlying mechanism of delivery. The preparation of polymeric nanoparticulate delivery have two essential objectives, first to make a solid 134network and second to avoid aggregation by incorporating surfactant or emulsifier. Formulations containing Nutraceuticals like probioticsprobiotics and antioxidants are available into the market. These marketed formulations are considered safe and maybe act as substitute for prescription drugs. This chapter highlights the recent development of nanotechnological approaches for delivery of nutraceuticals. The nanotechnological approaches specifically include the use of polymers for modulating nutraceuticals, which helps in increasing the bioavailability, targetability, oral absorption, etc. The chapters also entitle the preparation methods and mechanism of stabilization of nutraceuticals for oral and targeted delivery, further emphasizes the FDA’s current good manufacturing practices (GMPs) for nutraceutical formulations.
