Identification of the metabolites responsible for colour stability from different lamb sires and elucidation of the underlying biochemical pathways : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy in Biochemistry at Lincoln University
The browning of lamb meat colour during retail display is generally undesirable for consumers. This is especially important for the New Zealand meat industry that relies heavily on high-value, export chilled lamb products which are worth $400 – 630 million annually. The main objective of my study …

Alternative Feeding Resources of Mediterranean Origin to Improve Lamb Meat and Pork Quality
… days at refrigerated temperature, afterwards the colour stability and lipid oxidation (first experiment), and microbial spoilage (second experiment) were evaluated in the muscle longissimus dorsi. Dried citrus pulp strongly reduced meat lipid oxidation, while did not exert effects on colour …

Colour changes in nano-filled and micro-hybrid composite resins on exposure to spices.
Colour changes in composite resins after immersion in beverages such as coffee, tea, alcohol beverage and carbonated drinks have been reported. Although much work has been done to determine the staining susceptibility of composite resins to various liquid beverages, effects of spices on colour …

Effect of cullet level on amber glass quality, workability and commercial viability
… and blister levels, as well as composition and colour stability. Glass workability was assessed in terms of bottle faults due to checks, thin walls and cavity related defects. Commercial viability was assessed in terms of production efficiency and bottle breaking pressure. The results show that …

Evaluating Winemaking Applications of Ultrafiltration
… winemaking to improve sensory attributes such as colour, texture, mouthfeel, aroma, and flavour, possibly increasing the volume of highly sought-after wines. Comprising five intertwined projects, the initial screening project in Chapter 2 focuses on understanding the impact of UF on red and white …

Stability study in lead-halide perovskite light-emitting diodes
… perovskite emitters have advantages such as high colour saturation and low processing temperatures to compete with present inorganic and organic light emitting diode (LED) technologies. However, poor device stability continues to be the limiting factor for perovskite LEDs (PeLEDs) to be realised …

Vergleich der Farbstabilität milder und hochkonzentrierter Bleichmittel
Ziel dieser Studie war es, unter Erprobung einer computergestützten Farbanalyse, festzustellen, ob es Unterschiede im Erhalt der Farbstabilität zwischen niedrig konzentrierten (15%iges Carbamidperoxid) und hoch konzentrierten (35%iges Carbamidperosid) Bleichmitteln beziehungsweise zwischen den …

Bonding of additives to functional polyolefins by reactive blending
… of three hundred hours to assess the resulting stability of the materials. Diffuse reflectance FTIR (DRIFT) spectroscopy and X-ray photoelectron spectroscopy (XPS) provided an effective means to study oxidative degradation. IR spectroscopic measurements were used to determine the effectiveness …

Investigation of the oxidative degradation mechanisms and melt stabilisation of a new generation metallocene polytehylene
… of selected commercial stabilisers on the melt stability of the polymers. The unstabilised m-LLDPE polymer was extruded (pass I) using a twin screw extruder, at different temperatures (210-285°C) and screw speeds (50-20rpm) and was subjected to multiple extrusions (passes, 2-5) carried out under …

Characterization of dragon fruit (Hylocereus spp.) components with valorization potential
… have the potential to be utilized as a natural colouring agent. Dragon fruit pulp and puree also exhibited significant antioxidative activities. This was even more pronounced for the red-flesh species due to the presence of betacyanin. The pulp and puree showed shear-thinning behaviour due to …
