Abstract:
In Chapter 1 the fundamentals of MG and MG-water are reviewed before embarking on studying the mixtures of MG and oils. The typical phase ordering and crystallisation process are reviewed. Understanding the physical properties of lipids is fundamentally important, hence, relevant theories regarding the phase behaviour are discussed in the following section. Chapter 2 introduces synthesis, characterisation and experimental techniques used throughout the thesis. Particular attention is given to assess the limitations of these techniques when probing the phase ordering of MG-oil.  In Chapter 3 the phase diagram and the microstructure of MG in oils are presented by a set of experimental data from different techniques. Chapter 4 presents the experimental findings of the water effects in MG-oil systems. Chapter 5 considers the aging and metastability of MG-oil and its hydrated system (MG-oil with 3 wt\% water). The aging phenomena are quantified by the increase of melting enthalpy in differential scanning calorimetry (DSC) heating scans and the mechanism is understood by applying infrared spectroscopy. The changes of hydrogen bonding patterns by adding small quantity of water slows the aging process significantly. In Chapter 6 the effect of colloidal dispersions is discussed to modify the MG gel. Lipids such as MG form the gel-like material which can be widely applied in the food industry, cosmetics and other personal products. It is hoped that this thesis will provide stimulating insight into the lipid composite field and furthermore, motivate research in industry toward improvement of existing materials and discovery of innovative new products.
