Novel extraction and encapsulation strategies for food bioactive lipids to improve stability and control delivery

Abstract

Dietary bioactive lipids have been recovered from diverse sources and shown to provide numerous health benefits. Like certain lipids, under normal processing and storage conditions, exposure to factors such as the presence of light, elevated temperature, and oxygen causes degradation and loss of nutritional value and functionality limiting their use. Furthermore, their hydrophobic nature makes incorporation into water-based products challenging. Delivery systems that entrap bioactive components such as micro/nano-encapsulation have been used over the years to enhance solubility, stability, safety, consumer acceptability, delivery, and bioavailability. This review examines recent developments in the extraction, delivery systems, and application of loaded bioactive lipid-rich micro/nanoparticles in food and nutraceutical products.
