Schueuermann, Claudia (Thesis, Doctor of Philosophy, 2016)

Wine is a highly complex alcoholic beverage and its flavour and quality depends on a multitude of factors including soil composition, climate, vintage, grapevine, viticulture, and oenology practices. Mt. Difficulty Wines ...
The feasibility of using pulsed electric field processing to increase the phytochemical contents of plant-based foods

Leong, Sze Ying (Thesis, Doctor of Philosophy, 2016)

This thesis aimed to investigate how pulsed electric field (PEF) at low electric field strengths (E ≤ 2 kV/cm) influenced the phytochemical contents of plant-based foods. Effects of PEF on cell electroporation to enhance ...
The effect of rigor temperature, ageing and display time on the quality of hot boned beef semimembranosus muscle

Mungure, Tanyaradzwa Emmanuel (Thesis, Master of Science, 2015)

Lipid oxidation is a primary mechanism that causes a decrease in meat quality. Abundant research has been done on the eating and keeping quality attributes of beef as affected by rigor temperature, but limited work has ...
Chinese consumers' freshness perceptions: A case study of orange juices

Zhang, Ting (Thesis, Master of Science, 2015)

Ranking sixth in the world for consumption of orange juice, China creates tremendous opportunities for Western beverage manufacturers to develop value-added orange juice products that satisfy Chinese consumers’ needs. ...
Effect Of Processing On The Flavour Character Of Arabica Natural Coffee

Fernandez Alduenda, Mario Roberto (Thesis, Doctor of Philosophy, 2015)

In the context of the current, flourishing specialty coffee industry, the processing of the coffee bean at the origin is increasingly becoming the main differentiation tool for specialty coffee producers around the world. ...
The Impact Of Pulsed Electric Field (PEF) Processing On Solid Food Materials

Faridnia, Farnaz (Thesis, Doctor of Philosophy, 2015)

Pulsed electric field (PEF) processing involves subjecting food, placed between two electrodes, to pulsed high voltage electric fields for a very short time (μs to ms), inducing pore formation and hence permeabilization ...
Cheese as a delivery vehicle for green tea catechins

Rashidinejad, Ali (Thesis, Doctor of Philosophy, 2015)

Dietary polyphenols, especially those from green tea, have received growing attention lately due to the potential antioxidant activities. Many health benefits have been shown for green tea polyphenols, particularly the ...
An investigation of young and educated Chinese consumers' perceptions of beverages treated by pulsed-electric field and high hydrostatic pressure processing

Lee, Pui Yee (Thesis, Doctor of Philosophy, 2015)

High hydrostatic pressure processing (HPP) and pulsed-electric field (PEF) are processing technologies that add value to foods by improving safety through lowering microbial loads in addition to minimizing the changes in ...
Generation of bioactive compounds from slaughterhouse animal blood using enzymatic hydrolysis

Bah, Clara Shui Fern (Thesis, Doctor of Philosophy, 2015)

Slaughterhouse blood is a by-product of the meat production industry and represents a rich source of protein with potential beneficial properties. The results reported in this thesis describe the generation of hydrolysates ...
The Impact of Food Allergies on Quality of Life

Peniamina, Rana Lori (Thesis, Doctor of Philosophy, 2015)

Food allergies are a growing health concern, yet scientific understanding of how individuals’ lives are affected by food allergies is limited. The aims of this project were to explore the factors that affect the lives of ...
The influence of volatile organic compound release, texture and microstructure on the perception of apple flavour

Ting, Valentina Jiin Lee (Thesis, Doctor of Philosophy, 2015)
