Detection and quantification of spice adulteration by near infrared hyperspectral imaging
(Stellenbosch : University of Stellenbosch, 2011-03)
ENGLISH ABSTRACT: Near infrared hyperspectral imaging (NIR HSI) in conjunction with multivariate image analysis was
evaluated for the detection of millet and buckwheat flour in ground black pepper. Additionally, ...
Development of a sensory lexicon and sensory wheel for rooibos (Aspalathus linearis) and the role of its phenolic composition on taste and mouthfeel.
(Stellenbosch : University of Stellenbosch, 2011-03)
ENGLISH ABSTRACT: The sensory characteristics and chemical composition of rooibos infusions were analysed to establish the extent of variation in sensory attributes and compositional parameters, and investigate whether ...
Sensory and phenolic profiling of Cyclopia species (Honeybush) and optimisation of the fermentation conditions
(Stellenbosch : Stellenbosch University, 2012-03)
ENGLISH ABSTRACT: The sensory profiles, phenolic composition and colour of honeybush infusions, prepared from six Cyclopia species (C. sessiliflora, C. longifolia, C. genistoides, C. intermedia, C. subternata and C. ...
HPLC method development for characterisation of the phenolic composition of Cyclopia subternata and C. maculata extracts and chromatographic fingerprint analysis for quality control
(Stellenbosch : Stellenbosch University, 2013-12)
ENGLISH ABSTRACT: The phenolic composition of Cyclopia species is believed to be partially responsible for the numerous health
promoting properties associated with their extracts. Current quality control measures do not ...

Assessment of variance in measurement of hectolitre mass of wheat and maize, using equipment from different grain producing and exporting countries
(Stellenbosch : University of Stellenbosch, 2008-03)
South Africa as well as other grain producing and exporting countries’ grading systems strongly
relies on hectolitre mass (HLM) as a guide to grain quality. It is known that these countries use either
one of two types ...
PCR-based DGGE identification of bacteria and yeasts present in South African grape must and wine
(Stellenbosch : Stellenbosch University, 2007-03)
ENGLISH ABSTRACT: Wine production involves complex interactions between a variety of yeasts and bacteria. Conventional microbiological methods can be used to identify the different microorganisms present in wine, but prove ...
Detection and identification of wine spoilage microbes using PCR-based DGGE analysis
(Stellenbosch : University of Stellenbosch, 2009-03)
Grape juice is transformed into wine through the complex processes of alcoholic and
malolactic fermentation that is performed by yeasts, lactic acid bacteria and acetic acid
bacteria. However, the microbes involved in ...
