Solute-Polymer States of Water and the Physico-Chemical Properties of Food Model Systems (Crystallinity, Sorption, Hysteresis, Starch)
… of solute-polymer mixtures as related to water binding, solute content and water activity (a(,w)). It was hypothesized that these properties were due to the presence of solute (SOL) and polymer (POL) water. The second objective was to develop a non-invasive analytical method for SOL and …

The Physiological Response of Staphylococcus Aureus Mf-31 to Conditions of Reduced Water Activity
… was able to grow in environments at reduced water activity (a(,w)) was investigated. This project was approached by studying the influence of reduced a(,w) on the intracellular free amino acid pools, amino acid transport, glutamine synthesis, and proline oxidation in S. aureus. In addition, …

Enzymatic Enhancement of Water Removal In the Dry Grind Corn to Ethanol Process
The removal of water from coproducts in the fuel ethanol process requires a significant energy input. The drying of the coproducts is responsible for as much as 32% of the total utilities cost of the process. In this study, improvements in the energy and water balances of the corn to ethanol …

Delivering β-glucan via selected bakery systems : cake
… response. Due to its viscosity enhancing and water binding properties, β-glucan is considered as a potential fat replacer. In this thesis β-glucan from oat and barley were studied as functional ingredients in bakery systems using cake as a model to deliver health benefits.

Interactions Among Protein, Electrolytes and Water Determined by Nuclear Magnetic Resonance and Hydrodynamic Equilibria (Nmr)
… is an important ingredient in meat products, water binding by muscle protein in the presence of salt has not been investigated. Biceps femoris muscle was dialyzed against distilled water and increasing levels of salt were added to seven aliquots. Sorption and desorption isotherm data at …

Protein deposition at polymer surfaces:the bulk and surface structure-property effects of hydrogels
… the hydrogels were established using equilibrium water content measurements, together with water-binding studies by differential scanning calorimetry (D.S.C.). Hamilton and captive air bubble-contact angle techniques were employed to characterise the hydrogel-water interface and from which by a …

Novel materials for membrane separation processes
… good strength and elasticity in addition to good water binding ability. The synthesis of derivatives was attempted by both enzymatic and chemical methods. Enzyme synthesis involved the transesterification of cis-DHCD with a number of trichloro and trifluoroethyl esters using the enzyme lipase …

Effects of Citrullus lanatus seed (Egusi) protein isolate on lipid peroxidation in malnourished rat fed on high fat diets
… deffated egusi seeds were extracted with water (pH 10). The extracted proteins were precipitated at pH 5, centrifuged and freeze-dried to obtain the protein isolate. Proximate composition shows that egusi seed isolate is rich in protein (63.4 %), and minerals. Functional properties …

Synthesis of novel cylic monomers for hydrogel polymers
… could have good mechanical properties and good water binding ability. A model compound for cis-DHCD was sought, as cis-DHCD was expensive and stable under only a narrow range of conditions. Catechol was found to be an excellent model for cis-DHCD, as 1H NMR spectroscopy indicated that both …

Novel cationic polymers for use at biological interfaces
… have been characterised in terms of their water binding, mechanical and surface properties. It has been concluded that the incorporation of these monomers does not adversely affect the properties of such hydrogels and that these materials are potential candidates for further development for …
