An Investigation of Factors that Contribute to Dihydroxyacetone Variation Observed in New Zealand Leptospermum scoparium
(University of Waikato, 2013)Honey derived from Leptospermum scoparium (commonly known as mānuka) is known to have anti-bacterial activity that is not entirely accounted for by the presence of hydrogen peroxide.1 This is known as non-peroxide activity ... -
Analysis of Amino Acids in Mānuka Honey
(University of Waikato, 2015)Honey, a natural product produced by honeybees, has a complex matrix of sugars proteins, minerals, vitamins, enzymes and free amino acids. Amino acids, obtained from the nectar of plants, account for 50-30 mg/kg of honey, ... -
Analysis of Nucleosides and Nucleotides in Milk and Infant Formula
(University of Waikato, 2013)Nucleotides have been routinely supplemented to infant formulas due to the important roles they play in metabolism and to replicate the higher concentrations typically found in human milk. A method utilising anion exchange ... -
Asymmetric Ligands Derived from Carbohydrates
(University of Waikato, 2011)This thesis describes the incorporation of carbohydrate groups in thiourea, 1, or iminophosphorane, 2, ligands. Several carbohydrate acyl thioureas, 3, were synthesised from the reaction of protected and unprotected ... -
Behaviour of trace organics and dissolved organic matter in granular activated carbon filters for drinking water supply
(The University of Waikato, 2021)Granular and biological activated carbon (GAC and BAC) filters are widely used to remove organic compounds from drinking water sources during municipal drinking water treatment. Common uses of GAC filters include removal ... -
Categorisation and Discrimination of Automotive Glass Fragments by Laser Ablation Inductively Coupled Plasma Mass-Spectrometry (LA-ICP-MS) for Forensic Purposes
(University of Waikato, 2010)Glass is one of the most common types of trace evidence found at crime scenes and on suspects. Refractive index is presently used for matching recovered and control samples of glass. However, increased quality control in ... -
Characterisation of watersoluble polysaccharides produced during prehydrolysis of pinus radiata
(The University of Waikato, 2010)An aqueous prehydrolysate (or prehydrolysis liquor) was produced during a mild hot-water prehydrolysis (90 minute ramp to 175 C) of commercial radiata pine wood chips. Oligosaccharide and polysaccharide material was separated ... -
Development of a Method for the Quantitative Detection of Honey in Imported Products.
(University of Waikato, 2010)The carbohydrate composition of Asian honeys was determined using analysis of per-O-trimethylsilylated sugar alditols by GC-FID. This method was established to detect the presence and quantify honey in imported products ... -
Development of a Method for Trace Analysis of Dioctyl Sodium Sulfosuccinate by Liquid Chromatography Mass Spectrometry and its Application to Samples from the MV Rena Incident
(University of Waikato, 2015)The grounding of the MV Rena off the coast of Tauranga, New Zealand in 2011 prompted the application of Corexit® oil spill dispersants in an attempt to mitigate the impact of the spilled oil to coastal ecosystems. A ... -
Development of novel approaches for industrial fermentation of menaquinone-7
(The University of Waikato, 2018)Vitamin K, an anti-haemorrhagic factor discovered by the Danish nutritional biochemist Henrik Carl Peter Dam in 1929, is capable of correcting dietary-induced bleeding disorders in chickens. It is essential for blood ... -
Examination of the Molecular Mass of Polyhydroxypolyamides
(The University of Waikato, 2010)The work described in this thesis investigated the use of size exclusion chromatography (SEC) to fractionate a variety of different polyhydroxypolyamide (PHPA) samples for analysis by matrix assisted laser desorption ... -
The Flavonoid Profile of New Zealand Manuka Honey
(The University of Waikato, 2009)Flavonoids are a class of natural products derived from plants which are incorporated into honeys through propolis, nectar and pollen. Research has shown that many honeys possess characteristic flavonoid profiles which can ... -
Identification of the floral source of New Zealand honeys
(The University of Waikato, 2009)Depending on the nectar source, honey is either unifloral (derived mostly from one plant type), or polyfloral (derived from multiple plant types). Unifloral honey has characteristic sensory properties, and is therefore of ... -
In vivo utilisation of fructooligosaccharides by sheep faecal bifidobacteria and in vitro antagonistic effects against intestinal pathogens
(The University of Waikato, 2003)The application of pro-, pre, and synbiotics has been studied primarily in humans and some other monogastric animals. Very few studies have been made to determine their effects on the ruminant intestinal microflora. This ... -
Investigation of extractable materials from biochar
(University of Waikato, 2012)Biochar has been used to improve soil productivity and has been a subject of discussion since 1804. However, research and development of biochar for environmental purposes on a global scale are a recent development. Due ... -
An investigation of the stability of yacon storage roots under commercial conditions and the feasibility of preparing blackcurrant-yacon juice mixtures for the retail market
(University of Waikato, 2012)The stability of fructooligosaccharides (FOS) was investigated in yacon (Smallanthus sonchifolius Poepp. & Endl., Asteraceae) storage roots and blackcurrant-yacon juice mixtures. The roots and syrup are from yacon plants ... -
Isolation, Characterization and Synthesis of a Phenyl-substituted Pyrrole Isolated from the Flavonoid Fraction of Mānuka Honey
(University of Waikato, 2011)Compound 1, which occurs in the flavonoid fraction of mānuka honey and showed a statistical correlation with the non-peroxide antibacterial activity of the honeys, was extracted from fifteen kilograms of mānuka honey using ... -
Kinetics of Conversion of Dihydroxyacetone to Methylglyoxal in Honey
(University of Waikato, 2015)Mānuka honey contains a unique non-peroxide antibacterial activity which is highly sought after due to the perceived health benefits. Methylglyoxal (MGO) is the compound predominately responsible for this non-peroxide ... -
New Zealand seagrass (Zostera muelleri) response to acute sedimentation: Linking non-structural carbohydrate reserves to resilience
(The University of Waikato, 2020)Seagrass meadows form healthy near-coastal marine environments that provide a wide range of ecosystem services in New Zealand and Australia. However, seagrass habitats are declining regionally and globally. It is therefore ... -
Oxidative Decolouring of Bloodmeal Using Peracetic Acid
(University of Waikato, 2015)Bloodmeal is an ancillary product of the agricultural industry, containing 80 – 100 % protein, and has been used to create a bio-based plastic called Novatein Thermoplastic Protein®, with a proprietary blend of sodium ...
