The National School Nutrition Programme (NSNP) in South Africa provides thousands of needy children with school meals on school days. One, and in some cases 2, of these meals per week are soya based. A review of the NSNP revealed that many children do not eat on those days because they find the soya mince meal unappetising. As the meal served withi...

The rapidly growing global population emphasises the need for high-yielding, sustainable, yet nutritious food crops, which produce consistent yields under varying agricultural conditions. There are various critical research hypotheses that propose solutions for this scenario with some of the main focus areas being crop management and precision farm...

Protein content was determined using both the nitrogen to protein conversion factor of 6.25 and the summation of amino acids for four of the potato cultivars (Solanum tuberosum L.) most commonly consumed in South Africa. Protein content for the cultivars varied between 1.65 g/100 g and 2.14 g/100 g fresh-weight when using protein conversion and 1.6...

“Slap chips” are a traditionally South Africa product that is widely consumed throughout the country. These chips are similar to French fries but are thicker and fried for a longer time at a lower temperature using a double fry method. It is assumed that different textural properties of potatoes will lead to certain cultivars being better suited fo...

Biodiversity is considered a critical measure of the agricultural health of the world. Not only does increased biodiversity contribute to nutrient production and consumption, but it acts as a safeguard against food shortages due to pests and diseases by spreading the risk. Biodiversity can improve dietary diversity in such a way to ultimately contr...

ABSTRAT There is a global increase in the production, processing and consumption of potatoes, especially in developing countries. The scale of the different varieties available today has led to a demand by end users to have some indication of fit for purpose. Reliable, scientifically validated objective methods are needed to group potatoes in order...

The FAO/WHO Expert Consultation Report (1998) recommended that both the chemical composition and physiological effect of food carbohydrates, including Glycaemic Index (GI), should be considered in guiding healthy food choices. Towards this end a rapid assessment method was developed to aid the food industry during product development, mainly for sc...
