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 physicists publish in prestigious Nature journal

In August 2017, the Boyden Observatory in Bloemfontein played a major role in obtaining optical observations of one of the biggest discoveries ever made in astrophysics: the detection of an electromagnetic counterpart to a gravitational wave event.
 
An article reporting on this discovery will appear in the prestigious science journal, Nature, in October 2017. Co-authors of the article, Dr Brian van Soelen and Hélène Szegedi, are from the Department of Physics at the University of the Free State (UFS). Both Dr Van Soelen and Szegedi are researching multi-wavelength astronomy.
 
Discovery is the beginning of a new epoch in astronomy
 
Dr van Soelen said: “These observations and this discovery are the beginning of a new epoch in astronomy. We are now able to not only undertake multi-wavelength observations over the whole electromagnetic spectrum (radio up to gamma-rays) but have now been able to observe the same source in both electromagnetic and gravitational waves.”
 
Until recently it was only possible to observe the universe using light obtained from astronomical sources. This all changed in February 2016 when LIGO (Laser Interferometer Gravitational-Wave Observatory) stated that for the first time they had detected gravitational waves on 14 September 2015 from the merger of two black holes. Since then, LIGO has announced the detection of two more such mergers. A fourth was just reported (27 September 2017), which was the first detected by both LIGO and Virgo. However, despite the huge amount of energy released in these processes, none of this is detectable as radiation in any part of the electromagnetic spectrum. Since the first LIGO detection astronomers have been searching for possible electromagnetic counterparts to gravitational wave detections. 
 
Large international collaboration of astronomers rushed to observe source
 
On 17 August 2017 LIGO and Virgo detected the first ever gravitational waves resulting from the merger of two neutron stars. Neutron star mergers produce massive explosions called kilonovae which will produce a specific electromagnetic signature. After the detection of the gravitational wave, telescopes around the world started searching for the optical counterpart, and it was discovered to be located in an elliptical galaxy, NGC4993, 130 million light years away. A large international collaboration of astronomers, including Dr Van Soelen and Szegedi, rushed to observe this source.
 
At the Boyden Observatory, Dr Van Soelen and Szegedi used the Boyden 1.5-m optical telescope to observe the source in the early evening, from 18 to 21 August. The observations obtained at Boyden Observatory, combined with observations from telescopes in Chile and Hawaii, confirmed that this was the first-ever detection of an electromagnetic counterpart to a gravitational wave event. Combined with the detection of gamma-rays with the Fermi-LAT telescope, this also confirms that neutron star mergers are responsible for short gamma-ray bursts.  
 
The results from these optical observations are reported in A kilonova as the electromagnetic counterpart to a gravitational-wave source published in Nature in October 2017.
 
“Our paper is one of a few that will be submitted by different groups that will report on this discovery, including a large LIGO-Virgo paper summarising all observations. The main results from our paper were obtained through the New Technology Telescope, the GROND system, and the Pan-STARRS system. The Boyden observations helped to obtain extra observations during the first 72 hours which showed that the light of the source decreased much quicker than was expected for supernova, classifying this source as a kilonova,” Dr Van Soelen said.
