ABSTRACT
Nutraceuticals have inherent health-beneficial potentials like antioxidant properties along with anti-inflammatory, antimicrobial, and immune-potentiating effects, which support their use as therapeutic agents. Various nanoformulations like nanoemulsions, micelles, nanocapsules, solid lipid nanoparticles, nanochelates, liposomes, self-assembled nanoparticles, etc., have been synthesized for the efficient delivery of the nutraceuticals. Nutraceuticals are components of feed and foods which provide nutritional, functional, and therapeutic benefits to the body. Nutraceuticals are proven to enhance human health prevent chronic diseases and even to have therapeutic benefits. The most common and widely used nutraceuticals are omega-3 fatty acids, vitamins, carotenoids, polyphenols, and probiotic bacteria. Delivery systems should be appropriately fashioned to save value-added nutraceuticals from undesirable cross-interactions with other chemical ingredients and physical entities like pH, light, temperature, or oxygen during nutraceutical processing, storage, and transport. Polysaccharide-based delivery systems are preferable for nutraceutical applications due to their biocompatible and biodegradable nature and can be easily manipulated to achieve the required properties.
