Effect of oxygenation during maturation on phenolic composition, total antioxidant capacity, colour and sensory quality of pinotage wine
(SASEV, 2008-10)The effect of oxygenation on the phenolic composition, total antioxidant capacity (TAC), colour and sensory quality was investigated during the maturation of Pinotage wines. Oxygenation was carried out in discrete monthly ... -
Effect of pork rind and soy protein on polony sensory attributes
(OMICS International, 2015-01)This study determined whether commercially acceptable polony could be manufactured with varying quantities of chicken mechanically recovered meat (MRM), soy flour (S) and pork rind (R). The experimental design used was a ... -
Enzyme kinetics modelling approach to evaluate the impact of high CO2 and super-atmospheric O2 concentrations on respiration rate of pomegranate arils
(Taylor & Francis, 2017)Super-atmospheric O2 has been shown to affect respiration rate (RR), but no model describing its effect on RR for pomegranate arils has been reported. This study investigated the effects of four different gas compositions ... -
Escherichia coli with virulence factors and multidrug resistance in the Plankenburg River
(Academy of Science of South Africa, 2014)Escherichia coli is a natural inhabitant of the gut and E. coli levels in water are considered internationally to be an indication of faecal contamination. Although not usually pathogenic, E. coli has been linked to numerous ... -
The evaluation of the applicability of Fourier Transform Near-Infrared (FT-NIR) spectroscopy in the measurement of analytical parameters in must and wine
(South African Society for Enology and Viticulture, 2001)Fourier transform near-infrared (FT-NIR) spectroscopy can be used as a rapid method to measure the percentage of sugar and to discriminate between different must samples in terms of their free amino nitrogen (FAN) values. ... -
Evaluation of the phytoestrogenic activity of Cyclopia genistoides (honeybush) methanol extracts and relevant polyphenols
(American Chemical Society, 2007-04)Unfermented C. genistoides methanol extracts of different harvestings and selected polyphenols were evaluated for phytoestrogenic activity by comparing binding to both ER subtypes, transactivation of an ERE-containing ... -
Food consumption changes in South Africa since 1994
(Academy of Science of South Africa, 2015)Food consumption patterns in South Africa have changed dramatically over the past decades and likely will continue to change over the coming decades. Various food-related studies conducted over the last few decades ... -
Food ingredient extracts of Cyclopia subternata (Honeybush) : variation in phenolic composition and antioxidant capacity
(MDPI, 2012)Cyclopia subternata plants are traditionally used for the production of the South African herbal tea, honeybush, and recently as aqueous extracts for the food industry. A C. subternata aqueous extract and mangiferin (a ... -
Gamebirds : a sustainable food source in Southern Africa
(SpringerLink, 2013-02)In order to alleviate the current food security situation the world is faced with, it is essential to investigate meat sources which have the potential to be used in a sustainable manner. This review provides substantial ... -
Hyperglycemia-induced oxidative stress and heart disease-cardioprotective effects of rooibos flavonoids and phenylpyruvic acid-2-O-β-D-glucoside
(BMC (part of Springer Nature), 2017)Diabetic patients are at an increased risk of developing heart failure when compared to their non-diabetic counter parts. Accumulative evidence suggests chronic hyperglycemia to be central in the development of ... -
Importance and implications of antibiotic resistance development in livestock and wildlife farming in South Africa : a review
(South African Society for Animal Science, 2018-01-24)Antibiotic resistance (ABR) is regarded as one of today’s major global health challenges. The development of ABR in nature is a complex phenomenon with many influencing factors, of which the farming industry is labelled a ... -
Influence of lower substrate pH and retention time on the efficiency of a UASB bioreactor treating winery waste water
(South African Society for Enology and Viticulture, 1999)A mesophilic laboratory-scale upflow anaerobic sludge bed (UASB) bioreactor design was evaluated for the treatment of winery waste water. In the first experimental study, the hydraulic retention time (HRT) was shortened ... -
Intestinal transport characteristics and metabolism of C-glucosyl dihydrochalcone, aspalathin
(MDPI, 2017)Insight into the mechanisms of intestinal transport and metabolism of aspalathin will provide important information for dose optimisation, in particular for studies using mouse models. Aspalathin transportation across the ... -
Maceration before and during fermentation : effect on pinotage wine phenolic composition, total antioxidant capacity and objective colour parameters
(South African Society for Enology and Viticulture, 2006)Low-temperature maceration treatments (1, 2 and 4 days at 10 and 15°C) before fermentation and juice/skin mixing treatments (punching-down, pumping-over and rotor action every hour and every 3 hours) during fermentation ... -
Near infrared (NIR) hyperspectral imaging and multivariate image analysis to study growth characteristics and differences between species and strains of members of the genus fusarium
(SpringerLink, 2012-08)Near-infrared (NIR) hyperspectral imaging was used to study three strains of each of three Fusarium spp. (Fusarium subglutinans, Fusarium proliferatum and Fusarium verticillioides) inoculated on potato dextrose agar ... -
Nutraceutical value of yellow- and red-fleshed South African plums (prunus salicina lindl.) : evaluation of total antioxidant capacity and phenolic composition
(MDPI, 2014)Ten South African plum cultivars and selections, including yellow- and redfleshed plums from two harvest seasons were evaluated in terms of nutraceutical value (phenolic composition, total polyphenol content (TPC) and total ... -
Oxidative stability of blesbok, springbok and fallow deer droëwors with added rooibos extract
(Academy of Science of South Africa, 2015)The addition of rooibos extract (RBE) (0%, 0.25%, 0.50%, 1.0% RBE) to improve the oxidative stability of blesbok, springbok and fallow deer droëwors (dried sausage) was studied. RBE treatments had no effects (p>0.05) on ... -
PCR and DGGE detection limits for wine spoilage microbes
