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.”

Her advice to farmers is that they should make sure they are aware of the total cost (investment and operating costs) of an irrigation system. In most cases the investment cost is low, but the operating cost over the lifetime of the system is high.

“It is very important to have a look at the total cost and to install the most economic system,” says Marcill Venter, lecturer at the University of the Free State (UFS), who has done research on the economic sustainability of water-pipe systems.

Irrigation systems important components for farming
This research comes at a time when many farmers are relying on their irrigation systems due to persistent drought and low rainfall during 2016. South Africa has also experienced an abnormal increase in electricity tariffs in recent years. Due to tariff increases which threaten the future profitability of irrigation producers, the Water Research Commission (WRC) has launched and financed a project on the sustainable management of irrigation farming systems. “I had the opportunity to work on the project as a researcher,” says Venter.

The heart of every irrigation system is the water pipes that bring life to crops and livestock, and this is what Venter’s research is about. “Water pipes are part of the whole design of irrigation systems. The design of the system impact certain factors which determine the investment and operating costs,” she says.

Mathematical system to help farmers
Venter and Professor Bennie Grové, also from the Department of Agricultural Economics at the UFS, designed the Soil Water Irrigation Planning and Energy Management (SWIP-E) programming model as part of the WRC’s project, as well as for her master’s degree. “The model determines irrigation pump hours through a daily groundwater budget, while also taking into account the time-of-use electricity tariff structure and change in kilowatt requirements arising from the main-line design,” says Venter. The model is a non-linear programming model programmed in General Algebraic Modeling System (GAMS).

Design of irrigation system important for sustainability

The main outcome of the study is that the time-of-use electricity tariff structure (Ruraflex) is always more profitable than the flat-rate structure (Landrate). The interaction between the management and design of a system is crucial, as it determines the investment and operating costs. Irrigation designers should take the investment and operating cost of a system into account during the design process. The standards set by the South African Irrigation Institute (SAII) should also be controlled and revised.

Water-pipe thickness plays major role in cost cuts
There is interaction between water-pipe thickness, investment and operating costs. When thinner water pipes are installed, it increases the friction in the system as well as the kilowatt usage. A high kilowatt increases the operating cost, but the use of thinner water pipes lowers the investment cost. Thicker water pipes therefore lower the friction and the kilowatt requirements, which leads to lower operating costs, but thicker pipes have a higher investment cost. “It is thus crucial to look at the total cost (operating and investment cost) when investing in a new system. Farmers should invest in the system with the lowest total cost,” says Venter.
