Nutrient delivery systems are a new and fast-growing topic that covers various disciplines and has various applications in the food industry. This chapter seeks to bring current understanding on food-grade biopolymer-based approaches to developing nutrient compound delivery facilities up to date. The development of carriers derived from food biopolymers is a particular focus of research. In addition, several types of specifically updated nutrition delivery systems and their applications are reviewed. The different biopolymers employed for the assembly of carriers and particular synthesis techniques are studied in this chapter, emphasizing the aforementioned biological molecules. The prepared carriers will next be described in terms of characterization techniques and associated applications.
