January 22, 2025. German dairy company Hochland has teamed up with Belgian-Dutch food tech startup Those Vegan Cowboys to develop cheese without cows. The collaboration aims to use precision fermentation to produce casein, the key dairy protein, without traditional dairy farming.

A new approach to cheesemaking

Precision fermentation allows microbes to produce dairy proteins identical to those found in cow’s milk. Scientists insert DNA sequences into yeast or bacteria, instructing them to generate casein. These microbes ferment in controlled conditions, creating a protein that behaves just like traditional dairy casein.

Unlike plant-based cheese, which lacks the melt and stretch of dairy, this animal-free alternative promises the same taste and texture as conventional cheese. Hochland, one of Europe’s largest cheese producers, plans to test this protein in semi-hard and hard cheeses.

Who are these companies?

About Hochland

Founded in 1927, Hochland is a family-owned dairy company based in Germany. It produces a wide range of cheese products, including processed, cream and soft cheeses, under brands such as Almette and Patros. With a turnover exceeding €2.25 billion, Hochland operates internationally, with production sites in several countries. The company remains committed to both traditional dairy and sustainable innovations, such as precision fermentation.

In 2023, Hochland sold over 400,000 tonnes of cheese. The company employs approximately 6,200 people, with around 2,200 based in Germany and 4,000 abroad.

Hochland is committed to sustainability and innovation. They were the first company in the German dairy industry to be certified according to the EU Eco Audit Regulation (EMAS) in 1995. The company continues to expand its product range and explore new markets, maintaining its position as a key player in the global cheese industry.

About Those Vegan Cowboys

Those Vegan Cowboys, founded by Jaap Korteweg and Niko Koffeman, are pioneers in developing animal-free dairy alternatives. The company uses precision fermentation to create casein without relying on cows. Their goal is to revolutionise cheesemaking by providing sustainable and ethical dairy alternatives.

They previously gained recognition for founding The Vegetarian Butcher, a plant-based meat company later acquired by Unilever.

Sustainability at the forefront

Those Vegan Cowboys claim their process uses 80 per cent less carbon dioxide and only 20 per cent of the land and water required for dairy farming. The method also eliminates methane emissions, a major contributor to climate change.

Hochland sees precision fermentation as a way to expand its product range while reducing environmental impact. The company remains committed to traditional dairy but views innovation as key to meeting global food demand.

When will animal-free cheese hit the market?

While precision-fermented casein is not yet approved in Europe, Those Vegan Cowboys are working on regulatory approvals. The United States is expected to see the first launches in 2025, with Asia following soon after. Dutch consumers may have the chance to sample the cheese later this year.

If successful, this collaboration could reshape the dairy industry, providing consumers with a sustainable and ethical alternative to traditional cheese.

What is rBST, and how does it work?

Recombinant bovine somatotropin (rBST) is a synthetic version of a hormone naturally produced by cows. Scientists create it using genetic engineering. Once injected, it stimulates the production of insulin-like growth factor 1 (IGF-1), which increases milk production.

With rBST, cows can produce 10-15% more milk. However, this comes at a cost. The increased milk production places significant strain on a cow’s body, leading to health problems. These include mastitis (a painful udder infection), lameness and reduced fertility.

Farmers typically begin administering rBST about 8-10 weeks after a cow gives birth. Injections are given every two weeks to sustain higher milk yields.

The impact of rBST on animal welfare

One of the most significant criticisms of rBST is its effect on animal welfare. Cows treated with rBST face higher rates of health issues than untreated cows.

1. Mastitis: Mastitis is a bacterial infection of the udder that causes swelling, pain, and reduced milk quality. Studies show that rBST-treated cows have a higher risk of developing mastitis. Treating mastitis often requires antibiotics, which can further complicate milk quality.
2. Lameness: Increased milk production puts physical stress on a cow’s body. This strain can lead to lameness, a condition where cows struggle to walk or stand. Lameness affects a cow’s mobility and overall well-being, reducing their quality of life.
3. Reproductive problems: Cows injected with rBST are more likely to experience reproductive issues, including difficulty conceiving. This reduces their productivity and shortens their lifespan on farms.

Animal welfare organisations and consumers alike have raised concerns about these issues. Many argue that the increased milk yield does not justify the suffering caused to the cows.

How rBST affects milk quality

rBST also has a significant impact on the quality of milk it helps produce. While regulatory agencies like the FDA and WHO deem rBST milk safe for consumption, concerns remain.

Elevated IGF-1 levels

Milk from rBST-treated cows contains higher levels of insulin-like growth factor 1 (IGF-1). IGF-1 is a hormone linked to cell growth and repair in humans. Some studies suggest elevated IGF-1 levels could be associated with increased risks of certain cancers. Although these findings are not conclusive, many consumers prefer to avoid any potential risks.

Higher somatic cell counts

Cows with mastitis produce milk with higher somatic cell counts. These cells, which include pus and immune cells, can affect the milk’s flavour, texture and overall quality. Farmers must test milk regularly to ensure it meets safety standards, but elevated somatic cell counts remain a concern.

Antibiotic contamination

Treating mastitis often requires antibiotics. While farmers must follow withdrawal periods to prevent antibiotic residues in milk, mistakes can happen. The overuse of antibiotics in rBST-treated cows also contributes to the global problem of antibiotic resistance.

How rBST impacts cheese production

The effects of rBST on milk quality can extend to cheese production. Cheesemakers rely on high-quality milk to produce cheeses with the desired texture, flavour and appearance. Milk from rBST-treated cows may present challenges for artisans and industrial producers alike.

Altered milk composition

Higher somatic cell counts from rBST-treated cows can change the composition of milk. These changes may impact curd formation, a crucial step in cheesemaking. Poor curd formation can lead to lower yields and inconsistent cheese textures.

Consumer perception

Many cheese lovers prefer products made from rBST-free milk. Artisanal cheesemakers often highlight their use of high-quality, hormone-free milk to attract discerning customers. For these producers, avoiding rBST milk is essential to maintaining their reputation.

Global regulations on rBST

The use of rBST remains a controversial topic worldwide. While it is legal in some countries, many have banned it due to animal welfare and public health concerns.

Countries that allow rBST

The United States is the largest market for rBST use. Other countries, including Brazil, South Africa and some regions of Mexico, also permit its use.

Countries that ban rBST

Many countries, including those in the European Union, Canada, Australia and Japan, have banned rBST. These bans reflect concerns about animal welfare and the potential health risks of elevated IGF-1 levels in milk.

Choosing rBST-free cheese

As awareness of rBST’s impact grows, many cheesemakers in the United States are committing to using rBST-free milk. Here are a few notable examples:

Tillamook Cheese

Tillamook, a cooperative based in Oregon, uses milk exclusively from local farms that pledge not to use rBST. Their cheeses, including their iconic Cheddars, reflect their commitment to quality and sustainability.

Rogue Creamery

Rogue Creamery, another Oregon-based producer, uses organic, rBST-free milk for all its cheeses. Known for their award-winning Rogue River Blue, Rogue Creamery prioritises sustainability and animal welfare.

Cabot Creamery and Organic Valley

Cabot Creamery and Organic Valley are also leading names in rBST-free cheese production. Their products cater to consumers seeking natural and ethical dairy options.

Why choose rBST-free dairy?

Choosing rBST-free dairy products benefits cows, consumers and the environment. Supporting cheesemakers who avoid rBST promotes better animal welfare and ensures high-quality, natural cheese.

When shopping, look for labels stating “rBST-free” or choose trusted brands like Tillamook and Rogue Creamery. By making this choice, you’re helping to create a more sustainable and ethical dairy industry.

Conclusion

While rBST may boost milk production, the cost to cows, milk quality and cheese production is too high to ignore. Animal welfare issues, potential health risks, and altered milk composition make rBST a controversial and undesirable practice.

By choosing rBST-free cheese, consumers can enjoy better-tasting, ethically produced dairy while supporting sustainable farming practices. For the future of cows and cheese lovers alike, rBST-free is the way forward.

What is precision fermentation?

Precision fermentation is a biotechnology that uses microorganisms such as yeast, bacteria, or fungi to produce complex organic molecules. Unlike traditional fermentation, which has been used for centuries to create products like beer and yogurt, this technology takes advantage of advances in genetic engineering. Scientists can now “program” microorganisms to produce specific proteins, fats and other ingredients found in animal-based foods.

When it comes to dairy, the goal is to replicate the key protein (casein) that give milk its characteristic properties. This would enable the production of dairy products like cheese, butter and yogurt without involving cows. Instead, microorganisms are genetically engineered to produce these proteins. And they are then be combined with fats, sugars and other components to create milk alternatives with the same taste, texture, and functionality as animal milk.

How precision fermentation works in dairy production

1. Microbial Engineering: Microorganisms like yeast or bacteria are genetically modified to include genes that code for dairy proteins, such as casein or whey.
2. Fermentation Process: These engineered microbes are cultivated in large fermentation tanks, where they feed on simple sugars. As they grow, they begin to produce dairy proteins as part of their metabolic process.
3. Protein Harvesting: Once the fermentation is complete, the proteins are extracted and purified. These dairy proteins are molecularly identical to those found in cow’s milk.
4. Product Development: These proteins can be combined with other ingredients (fats, sugars, minerals) to create dairy-like products such as milk, cheese or yogurt. Since the proteins are identical to those produced by cows, the resulting products have the same taste, texture and functionality.

Why this process is a game-changer for the cheese industry

Cheese is one of the most complex dairy products to replicate because of its unique structure, flavour profiles and ageing process. The key to creating authentic cheese lies in the dairy proteins casein and whey. Those proteins, combined with fat globules, give cheese its elasticity, texture and ability to melt.

By using precision fermentation to produce casein and whey, companies can replicate cheese without needing to milk cows. This not only eliminates the need for animal agriculture but also allows for the creation of cheeses that are free from antibiotics, hormones and lactose. As a result, this may make cheese more accessible to people with lactose intolerance or dairy allergies.

Environmental impact

Moreover, the dairy industry is one of the largest contributors to greenhouse gas emissions, deforestation and water consumption in the agricultural sector. Traditional dairy farming requires vast amounts of land for grazing and growing animal feed. And cows emit methane, a potent greenhouse gas.

Precision fermentation offers a more sustainable solution. The fermentation process requires only a fraction of the land, water and energy compared to traditional dairy farming. Additionally, because the proteins are produced in a controlled environment, there is less waste and pollution.

Consequently, the carbon footprint of cheese production is drastically reduced. A report from the Good Food Institute suggests that precision fermentation could reduce dairy-related greenhouse gas emissions by up to 97% and water usage by 99%. This would make it one of the most environmentally friendly alternatives to conventional dairy production.

Ethical and animal welfare concerns

The ethical implications of this novel fermentation technology are profound. Factory farming, which is often criticised for its impact on animal welfare, can be eliminated from the equation. By producing dairy proteins without involving animals, precision fermentation offers a cruelty-free alternative that still allows consumers to enjoy their favorite cheese varieties.

Reshaping the cheese industry

The cheese industry is traditionally dominated by dairy from livestock. But with advancements in precision fermentation, the industry is about to be significantly disrupted. Here are a few ways precision fermentation may reshape the future of cheese:

1. Creating New Cheese Varieties: Precision fermentation allows for the creation of cheeses that may not have been possible through traditional means. For instance, microbial fermentation can be fine-tuned to enhance flavour profiles and create new and exciting varieties of cheese.
2. Meeting Dietary Preferences: As consumer demand for plant-based options grows, precision fermentation provides an alternative that still delivers the taste and texture of real dairy cheese. By creating animal-free casein and whey, companies can cater to vegans, vegetarians and flexitarians without compromising on quality.
3. Increasing Accessibility: With precision fermentation, there is potential for global scalability. Traditional dairy farming is limited by geography, climate and natural resources. On the other hand, precision fermentation can be conducted in virtually any location, making it easier to produce cheese in regions that may struggle with dairy production.

Advantages of precision fermentation over plant-based dairy

Precision fermentation offers significant advantages over plant-based dairy alternatives, primarily due to its ability to produce real dairy proteins like casein. Because of this, products like cheese can develop the same taste, texture and functionality as conventional dairy. In contrast, plant-based dairy often struggles to match the complex characteristics of dairy proteins.

Additionally, precision fermentation milk is nutritionally comparable to traditional milk. It provides complete proteins and essential nutrients without requiring fortification, unlike many plant-based alternatives. Finally, it also offers environmental benefits, using fewer resources such as land and water, while producing minimal waste.

Leading companies in precision fermentation

Several companies are leading the charge in the precision fermentation space, working to commercialize animal-free dairy proteins. Two notable pioneers in this space are Dairy X and Eden Brew.

Dairy X

Dairy X is one of the leading companies pushing the boundaries of precision fermentation to create sustainable dairy products. Their mission is to produce real dairy proteins without the need for cows. And they have made significant strides in replicating the key proteins necessary for cheese production.

Based in Israel, Dairy X uses cutting-edge microbial engineering to produce casein micelles identical to those found in cow’s milk. Their objective is to sell those micelles to leading CPG (Consumer Packaged Goods) brands around the world.

Eden Brew

Eden Brew is another key player in the precision fermentation revolution, with a strong focus on sustainability and animal welfare. Based in Australia, Eden Brew is leveraging precision fermentation to create dairy products that are indistinguishable from their cow-derived counterparts.

Eden Brew’s process involves using yeast to produce the same proteins found in cow’s milk. Eden Brew is particularly focused on creating dairy alternatives that are not just for vegans but for the broader population. Amongst their target market are those who seek animal-free products for environmental reasons.

The company has also partnered with large-scale producers and retailers to ensure that their production can be scaled to meet the needs of consumers globally. Their emphasis on sustainability has resonated with eco-conscious consumers. And they are working to commercialize their products on a large scale.

The company is currently testing their versions of precision fermentation milk and ice cream. Watch this space!

The challenges of producing precision fermentation cheese

While precision fermentation holds immense promise, there are still challenges to overcome.

One of the main hurdles is cost. While the technology has advanced rapidly, producing dairy proteins through precision fermentation is still more expensive than traditional dairy farming. However, as the technology continues to improve and scale, costs are expected to decrease, making animal-free dairy products more accessible to a wider audience.

Another challenge is consumer perception. While many people are open to the idea of plant-based and animal-free products, there is still a learning curve when it comes to understanding precision fermentation. Educating consumers on the benefits of precision fermentation—both in terms of sustainability and taste—will be key to driving widespread adoption.

Despite these challenges, the opportunities for precision fermentation in the dairy industry are vast. As technology improves, we can expect to see an increasing number of animal-free cheeses that are indistinguishable from traditional dairy.

Conclusion

Without a doubt, precision fermentation is set to revolutionise the dairy industry, particularly when it comes to cheese production. By harnessing the power of microbial engineering, companies like Dairy X and Eden Brew are leading the charge.

As we move toward a future where sustainability is paramount, this ground-breaking technology offers a promising solution to the environmental, ethical and logistical challenges posed by traditional dairy farming. With continued innovation and investment, this could soon become the standard for cheese production, allowing us to enjoy our favourite cheeses while supporting a healthier planet.
