Cheesemaking expertise from the Netherlands has given University of the Free State (UFS) students a unique taste of hands-on learning. From 10 to 22 August 2025, Eline van der Velde, a cheesemaking specialist and lecturer in food technology, spent two weeks at the UFS Paradys Experimental Farm teaching students, guiding dairy assistants, and working with staff to strengthen the university’s Dairy Processing Unit.

Supported by PUM – a Dutch volunteer organisation that connects international experts with local projects – her visit combined technical training with practical exposure, showing students the full process of transforming fresh milk into a range of cheeses.

 

Hands-on cheesemaking at the UFS

In interactive sessions, Van der Velde introduced students in the BSc Food Systems programme to the art and science of cheesemaking. They learned how to prepare paneer, halloumi, feta, mozzarella, and cottage cheese, while experimenting with flavoured varieties such as garlic-and-oregano and chilli cheese.

“I gave demonstrations on different types of coagulation and let the students try it out themselves. They asked great questions and enjoyed it so much that they wanted to come again for more practicals,” she said.

For many students, the opportunity was a first step into the practical realities behind food science. “It’s as if a whole world has opened up for our students,” said Dr Analie Hattingh, Lecturer and Production Manager at the Paradys Experimental Farm. “They don’t just hear about pH in theory – they can relate it to what they’ve seen and experienced here. That’s what prepares them for the workplace.”

“Due to food safety regulations all over the world, it is becoming increasingly difficult to take food science or food sustainability students into commercial factories. They don’t allow students or visitors anymore. At least with this facility here, our students can experience a real production environment and see how the industry works,” Dr Hattingh said. 

 

From farm girl to food technologist

Van der Velde’s passion for cheesemaking began on her uncle’s farm in the Netherlands, where she helped with milking and turning cheeses in storage. “Even though I grew up in the city, I think I’m more of a farm girl at heart,” she recalled.

Today, she teaches at an agricultural school and trains adults entering the food industry, while volunteering internationally through PUM. “I like to share knowledge – it’s not for me alone. That’s why I volunteer, to support projects across the world,” she explained.

 

Sustainability at the heart of the farm

The cheesemaking unit also forms part of the experimental farm’s commitment to sustainability. The cheeses are made from milk produced by Jersey cows on the farm, with careful attention to hygiene and quality. Byproducts are reused – whey is processed into ricotta, and the remainder is spread as fertiliser in the fields. “Nothing goes to waste,” Van der Velde noted.

Hattingh added that this integrated approach ensures that the farm serves as both an academic training ground and a model for sustainable food production. “We want to be self-sustaining and academically valuable, without competing with industry – to serve both the university and its students,” she said.

 

A shared learning journey

For dairy assistants Elisa Mosala and Martha Kantoane, working alongside Van der Velde and the students was equally rewarding. “It was nice, especially learning how to do different kinds of cheese,” said Kantoane.

Mosala agreed: “It was nice working with students and experiencing more every day. I learned new skills and got out of my comfort zone.”

Looking to the future, Van der Velde emphasised the value of involving students in the entire process – from milking to packaging and selling – so that they graduate with both knowledge and practical skills. She also believes in the potential of more international exchange: “These projects benefit both sides. Knowledge exchange in agriculture and food science is essential for building sustainable solutions worldwide.”

UFS study on cell development in top international science journal
2008-09-16

A study from the University of the Free State (UFS) on how the change in the packaging of DNA with cell development influenced the expression of genes, will be published in this week’s early edition of the prestigious international, peer-reviewed science journal, the Proceeding of the National Academy of Sciences of the USA (PNAS).

The PNAS journal has an impact factor of 10, which means that studies published in the journal are, on average, referred to by ten other scientific studies in a two year period. The South African Journal of Science, by comparison, has an impact factor of 0.7.

The UFS study, funded by the Wellcome Trust and the National Research Foundation (NRF), looked at how the change in the packaging of DNA with cell development influenced the expression of genes. It is very relevant to research on stem cells, an area of medicine that studies the possible use of undifferentiated cells to replace damaged tissue.

Prof. Hugh Patterton, of the Department of Microbial, Biochemical and Food Biotechnology at the UFS, who led the study, said: "We are extremely proud of this study. It was conceived in South Africa, it was performed in South Africa, the data were analysed in South Africa, and it was published from South Africa."

When a gene is expressed, the information encoded in the gene is used to manufacture a specific protein. In eukaryotes, which include humans, there is approximately 1m of DNA, containing the genes, in every cell. This length of DNA has to fit into a cell nucleus with a diameter of only about 10 micrometer. In order to fit the DNA into such a small volume, eukaryotic cells wrap their DNA onto successive protein balls, termed nucleosomes. Strings of nucleosomes, resembling a bead of pearls, is folded into a helix to form a chromatin fiber. The study from the UFS investigated how the binding of a specific protein, termed a linker histone, that binds to the length of DNA between nucleosomes, influenced the formation of the chromatin fiber and also the activity of genes.

"We found that the linker histone bound to chromatin in yeast, which we use as a model eukaryote, under conditions where virtually all the genes in the organism were inactive. It was widely believed that the binding of the linker histone caused the inactivation of genes. We studied the relationship between the amount of linker histone bound in the vicinity of each gene and the expression of that gene for all the genes in yeast, using genomic techniques. We made the surprising discovery that even through the linker histone preferentially bound to genes under conditions where the genes were shut off, this inactivation of genes was not caused by the binding of the linker histone and folding of the chromatin,” said Prof. Patterton.

He said: “Instead our data strongly suggested that the observed anti-correlation was due to the movement of enzymes along the DNA molecule, involved in processing the information in genes for the eventual manufacture of proteins. This movement of enzymes displaced the linker histones from the DNA. This finding now requires a rethink on aspects of how packaging of DNA influences gene activity."

Prof. Patterton said that his research group, using the Facility for Genomics and Proteomics as well as the Bioinformatics Node at the UFS, was currently busy with follow-up studies to understand how other proteins in nucleosomes affected the activities of genes, as well as with projects to understand how chemicals found in red wine and in green tea extended lifespan. "We are certainly having a marvelous time trying to understand the fundamental mechanisms of life, and the UFS is an exciting place to be if one was interested in studying life at the level of molecules," he said.
