ABSTRACT
Nutrients form an essential component for the growth and maintenance of our lives, but due to certain aspects such as their instability, lower bioavailability, and difficulties in formulation, it is quite challenging to develop carriers for the nutrient delivery. The aim of the present review is to discuss various advancements to innovate carriers for nutrients such as proteins, polysaccharides, lipids, etc. solid lipid nanoparticles, nanostructured lipid carriers, nanoemulsions, nanoliposomes, nanofibers, their applications in nutrient delivery, production perspectives, and formulation aspects are discussed. The importance of nanoscience in food technology and the societal aspects of nanotechnology-based innovations are being discussed. Based on the compatibilities, various kinds of nanocarriers are being studied. The advantages of phytochemicals encapsulation in nanocarriers are studied. Nutraceuticals offer advantages for disease prevention and its severity. To have a much greater effect of bioactive materials, promising methods have been suggested which would allow the reduction in the dosing for the desired bioactive material, controlled delivery. Nutrient delivery is aimed at food improvement, so extra care is to be taken while considering the developmental strategies. Various nutrients such as polyphenols, essential oils, 270bioactive indoles, peptides, etc., have been studied for the development of the delivery systems. Different technologies, including emulsification, electrospray, freeze-drying coacervation, spray drying, electrospinning, ionic gelation, etc., have all been tested for their practicability and applications in nutrition science.
