This book was released on 2013 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 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.

This book was released on 2014-07-02 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fabrication of biopolymer with nanotechnologies offers potential opportunities of natural byproducts re-utilization and new biomaterial creation. Those biopolymer platforms are designed to produce ingredients with better performance, manufacture functional food products, and eventually help nutraceuticals' body delivery via multiple administrations. With a couple of technological tools such as small molecular crosslinking, organocatalytic ring opening polymerization and electrospinning, we are able to realize the concept of biopolymer platforms for nutraceutical delivery. From laboratory test tube to plant manufacture, we are exploring ways of mass production of novel functional food products integrated with biopolymer-based nutraceutical delivery systems. Although it is a long march ahead, we will spend efforts to make it happen.

Download or read book Cyclodextrin Chemistry written by M. L. Bender and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemistry was at one time completely described in terms of collision theo ry, in which one molecule collided with another, sometimes producing reac tion. Then came the realization that enzymes which are highly efficient ca talysts, work by way of prior complexation, often stereospecific, which is then followed by chemical reaction. Thus, systems that exhibit "host-guest" relationships, i.e., that show complexing are being looked at an ever in creasing frequency. The cyclodextrins are the first and probably the most important example of compounds that exhibits complex formation. This is a book about the cyclodextrins. There are of course other compounds that exhibit "host-guest" relationships and thus bind other organic molecules, but so far they have not achieved the importance of the cyclodextrins. By their name it is obvious that cyclodextrins are cyclic compounds. The complexes that they form are therefore cyclic inclusion complexes. Because the complexes are cyclic in nature, complexation can be very strong, as op posed to 1t-complex, electrostatic, or apolar complexes in which complex formation is two-dimensional rather than three-dimensional. Cyclodextrins turn out to be excellent models of enzymes. This is proba bly not fortuitous because they were first sought since it was discovered that the principal binding in the enzyme chymotrypsin was a cyclic inclusion complex. Cyclodextrins can do more than form cyclic inclusion complexes, they can catalyze as well. But catalysis always occurs after complex formation.

Available in PDF, EPUB and Kindle. Book excerpt: Amphiphilic polymer co-networks (APCNs) are a type of polymeric hydrogel, their hydrophobic polymer segments and hydrophilic components produce less aqueous swelling, giving better mechanical properties than conventional hydrogels. This new class of polymers is attracting increasing attention, resulting in further basic research on the system, as well as new applications. This book focuses on new developments in the field of APCNs, and is organised in four sections: synthesis, properties, applications and modelling. Co-network architectures included in the book chapters are mainly those deriving from hydrophobic macro-cross-linkers, representing the classical approach; however, more modern designs are also presented. Properties of interest discussed include aqueous swelling, thermophysical and mechanical properties, self-assembly, electrical actuation, and protein adsorption. Applications described in the book chapters include the use of co-networks as soft contact lenses, scaffolds for drug delivery and tissue engineering, matrices for heterogeneous biocatalysis, and membranes of controllable permeability. Finally, an important theory chapter on the modelling of the self-assembly of APCNs is also included. The book is suitable for graduate students and researchers interested in hydrogels, polymer networks, polymer chemistry, block copolymers, self-assembly and nanomaterials, as well as their applications in contact lenses, drug delivery, tissue engineering, membranes and biocatalysis.
