(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 ... -
Characterisation of starch from malting barley grown in South Africa
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: South African barley is not always suitable for malting purposes due to unpredictable weather conditions. Malted barley is imported from other barley producing countries such as Australia, the United ... -
Characterisation of whole white maize kernels using spectral imaging
(Stellenbosch : Stellenbosch University, 2017-03)ENGLISH ABSTRACT: Maize (Zea mays L.) is the most important cereal crop grown in South Africa. It is produced widely across the country under diverse environments, and thus a variety of defects tend to occur. Grading is ... -
Characterisation of zein from South African maize of varying endosperm texture
(Stellenbosch : University of Stellenbosch, 2011-03)ENGLISH ABSTRACT: Maize is an important crop for both human and animal consumption. Maize kernel texture (kernel hardness) is an important quality trait for many sectors in the South African maize industry, where a harder ... -
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, ... -
Effect of endoxylanases, endoglucanases and their combination on wheat flour bread quality
(Stellenbosch : University of Stellenbosch, 2009-03)Endoxylanases are known to improve dough stability, oven spring, loaf volume, crumb structure and shelf life. The use of endoglucanases (cellulases) usually results in increased bread loaf volume, bread score and reduced ... -
Effect of substituting baking water with brewer's spent grain supernatant on the micro-structure and crumb structure of white wheat flour bread
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: The ubiquitous opinion regarding brewer’s spent grain (BSG), is that it is currently underutilised, based on its residual nutritional contents and potential for re-use. This is a process by-product ... -
Effects of packaging and storage condition on functional properties and quality attributes of cassava flour (CVS. ‘TME 419’ AND ‘UMUCASS 36’)
(Stellenbosch : Stellenbosch University, 2015., 2015-04)ENGLISH ABSTRACT: Cassava flour is recommended for substitution with wheat flour in composite flour for baking. The potential use of cassava flour in the food and pharmaceutical industries is attributed to its gluten-free ... -
Evaluating Namibian macrophytic algae as dietary source for South African abalone (Haliotis midae)
(Stellenbosch : University of Stellenbosch, 2009-03)An 84-day study was conducted to find a suitable diet and feeding level for the culture of South African abalone (Haliotis midae) in Namibia. Two experimental diets, namely, a seaweed diet (SWD) Laminaria pallida (macrophytic ... -
The evaluation of foodborne pathogenic bacteria using near infrared (NIR) hyperspectral imaging and multivariate image analysis
(Stellenbosch : Stellenbosch University, 2018-12)ENGLISH ABSTRACT: Near-infrared (NIR) hyperspectral imaging (HSI) and multivariate image analysis (MIA) was investigated for its potential as a rapid analytical method for the identification of foodborne pathogenic bacteria ... -
