(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: The South African game meat industry operates as a free-market enterprise; however, this can create certain problems for producers and consumers. For example, in South Africa no standardised meat cuts ... -
Determination of the microbiological safety of selected fresh produce of informal retailers point-of-sale
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: The global consumption of fresh produce has increased as consumers have become more health conscious. With the rise of fresh produce consumption, fresh produce related foodborne outbreaks also increased ... -
Antibiotic resistant bacteria prevalent in livestock and wildlife species in South Africa
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: Much research has focussed on the fate of antibiotics in clinical settings whereas research of antibiotics in natural environments has been comparatively limited. It has been hypothesised that wildlife ... -
Evaluating the disinfection efficacy of low-pressure ultraviolet irradiation on river water
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: Irrigation water has been identified as one way by which fresh produce can become contaminated with pathogens. This is a concern in South Africa, where some rivers used for the irrigation of fresh produce ... -
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 ... -

(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: To facilitate a better relationship with adjacent communities, the Kruger National park (KNP) is investigating the possibility of sustainable offtakes of buffalo and using some of the meat as cooked stew ... -
Genotyping South African wheat germplasm for hardness alleles
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: Wheat grain kernel hardness (GKH) is one of the most important quality properties of wheat (Triticum aestivum). The molecular basis of GKH is determined by the combination of Puroindoline a (Pina- D1) ... -
The physicochemical properties and stability of aspalathin in micro- and nanoencapsulated green rooibos extract formulations
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: Green rooibos extracts with high aspalathin content have potential as nutraceutical food ingredients based on their properties relating to the prevention of metabolic syndrome. However, delivery of green ... -
