RESUMO
Core-shell structures exhibit a number of distinct absorptive properties that make them attractive tools for use in a range of industrial contexts including pharmaceuticals, biotechnology, cosmetics, and food/agriculture. Several recent studies have focused on the development and fabrication of zein-based core-shell structures for a range of functional material deliveries. However, no recent review article has evaluated the fabrication of such core-shell structures for food-based applications. In this paper, we therefore survey current approaches to fabricating different zein-based platforms including particles, fibers, films, and hydrogels that have appeared in a variety of functionally relevant applications. In addition, we highlight certain challenges and future research directions in this field, thereby providing a novel perspective on zein-based core-shell structures.
