As a public higher-education institution in South Africa with a responsibility to contribute to public discourse, the University of the Free State (UFS) will be presenting the webinar as part of the Free State Literature Festival’s online initiative, VrySpraak-digitaal. 

The aim of the webinar series is to discuss issues facing South Africa by engaging experts at the university and in South Africa. Some of the topics for 2021 include, among others, reimagining universities for student success; corruption in South Africa – the endemic pandemic; South African politics and the local government elections; and Is South Africa falling apart. In 2020, the webinar series saw the successful participation of leading experts discussing COVID-19 and the crisis facing the country socially, economically, and politically. 

This year, in lieu of the Free State Arts Festival, the UFS will present the webinar virtually over a period of six months. 

Fifth webinar presented on 28 September 2021

A number of surveys have found some degree of vaccine hesitancy among the public. This webinar will clarify why we need to vaccinate against COVID-19 and why vaccines are safe. A major development in the COVID-19 pandemic has been the arrival and distribution of safe and effective vaccines. As the Delta variant of SARS-CoV-2 spreads around the world, the vaccine has proven to be safe and effective enough to prevent severe life-threatening COVID-19 complications. Although vaccines do not fully protect everyone who is vaccinated, nor guarantee zero transmission, a great deal of adherence to other measures is still required. Returning to a new normal routine of life can only happen as more people are vaccinated.


Date: Tuesday, 28 September 2021
Topic: Why vaccinate?
Time: 12:30-14:00
RSVP: Alicia Pienaar, pienaaran1@ufs.ac.za by 24 September 2021

Is milk really so well-known, asks UFS’s Prof. Osthoff
2011-03-17

Prof. Garry Osthoff opened a whole new world of milk to the audience in his inaugural lecture, Milk: the well-known (?) food, in our Department of Microbial, Biochemical and Food Biotechnology of the Faculty of Natural and Agricultural Sciences.

Prof. Osthoff has done his research in protein chemistry, immuno-chemistry and enzymology at the Council for Scientific and Industrial Research (CSIR) in Pretoria and post-doctoral research at the Bowman-Grey School of Medicine, North Carolina, USA. That was instrumental in establishing food chemistry at the university.
 
He is involved in chemical aspects of food, with a focus on dairy science and technology. He is also involved in the research of cheese processing as well as milk evolution and concentrated on milk evolution in his lecture. Knowledge of milk from dairy animals alone does not provide all the explanations of milk as food.
 
Some aspects he highlighted in his lecture were that milk is the first food to be utilised by young mammals and that it is custom-designed for each species. “However, mankind is an opportunist and has found ways of easy access to food by the practice of agriculture, where plants as well as animals were employed or rather exploited,” he said.
 
The cow is the best-known milk producer, but environmental conditions forced man to select other animals. In spite of breeding selection, cattle seem not to have adapted to the most extreme conditions such as high altitudes with sub-freezing temperatures, deserts and marshes.
 
Prof. Osthoff said the consumption of the milk as an adult is not natural; neither is the consumption of milk across species. This practice of mankind may often have consequences, when signs of malnutrition or diseases are noticed. Two common problems are an allergy to milk and lactose intolerance.
 
Allergies are normally the result of an immune response of the consumer to the foreign proteins found in the milk. In some cases it might help to switch from one milk source to another, such as switching from cow’s milk to goat’s milk.
 
Prof. Osthoff said lactose intolerance – the inability of adult humans to digest lactose, the milk sugar – is natural, as adults lose that ability to digest lactose. The symptoms of the condition are stomach cramps and diarrhoea. This problem is mainly found in the warmer climates of the world. This could be an indication of early passive development of dairy technology. In these regions milk could not be stored in its fresh form, but in a fermented form, in which case the lactose was pre-digested by micro-organisms, and the human population never adapted to digesting lactose in adulthood.
 
According to Prof. Osthoff, it is basically the lactose in milk that has spurred dairy technology. Its fermentation has resulted in the development of yoghurts and all the cheeses that we know. In turn, the intolerance to lactose has spurred a further technological solution: lactose-free milk is currently produced by pre-digestion of lactose with enzymes.
 
It was realised that the milks and products from different species differed in quality aspects such as keeping properties and taste. It was also realised that the nutritional properties differed as well as their effects on health. One example is the mentioned allergy against cow’s milk proteins, which may be solved by the consumption of goat’s milk. The nutritional benefits and technological processing of milk aroused an interest in more information, and it was realised that the information gained from human milk and that of the few domesticated species do not provide a complete explanation of the properties of milk as food. Of the 250 species of milk which have been studied, only the milk of humans and a few domesticated dairy animals has been studied in detail.
