DescriptionThe main objective of this research is to fabricate biopolymer platforms for nutraceutical delivery. Comprehensive physical and chemical tools have been utilized, and the engineered biopolymer platforms are promising to fulfill the demand of nutraceutical human transportation. However, single platform is not able to maintain the performance through varying administration routes. Under such circumstance, this work is driven by the premise to satisfy the multiple administrations of nutraceuticals. The work in this dissertation puts emphasis on the development and characterization of biopolymer-based platforms that enable food scientists better the design nutraceutical ingredients. Multiple approaches, small molecule crosslinking, organocatalytic ring-opening polymerization, polymer blending and electrospinning are leveraged to target chitosan-tripolyphosphate nanoparticle, mPEG-b-PVL star polymer, zein/F127 blend film, and zein electrospun fiber mat. The characterization of engineered platforms shed light on the following aspects: (i) molecular self-assembly at nano scale; and (ii) property and functionality at macro scale. And the structure-property relationship is established based on those two aspects. With controllable performance, biopolymer platforms are convenient to be integrated into product matrix as novel ingredients. Through investigation, it is demonstrated that controllable properties such as particulate gel’s tightness, particle aggregation, solid composite’s flexibility, and fibril organization are achieved by manipulating the nanostructures of biopolymers. The proposed platforms are conventionally extended to a rich variety of disciplines based on the fact that numerous applications in novel food ingredient, medical synthesis, tissue engineering, and product scaling up require the various biopolymer platforms.
