Breaking the mould! Scientists create different colours of ‘blue’ cheese – and say their pink, yellow and green versions taste just like the real deal

Scientists at the University of Nottingham have devised a way to create different colors of blue cheese.

Whether it’s a crumbly Stilton or a creamy Gorgonzola, any foodie knows that a cheese board isn’t complete without a blue cheese.

But these classic varieties could look very different in the future.

Scientists at the University of Nottingham have devised a way to create different colored blue cheese.

Despite looking quite outlandish, these Technicolor versions taste just like the real thing, according to Dr. Paul Dyer, who led the project.

“I think eating these new cheeses will give people a really satisfying sensory experience and hopefully it could bring new people to the market,” Dr Dyer said.

Scientists at the University of Nottingham have devised a way to create different colors of blue cheese.

While blue cheeses from different countries around the world can look and taste very different, they are all made from the same fungus: Penicillium roqueforti.

As the fungus grows, the pigmented spores grow through the cheeses, giving them both their blue color and flavor.

However, until now it was unclear how this blue pigment is produced.

In their new studio, the team They discovered that a biochemical pathway gradually forms blue pigments, starting with a white color, which progressively becomes greenish-yellow, pinkish-brown red, dark brown, light blue and finally dark greenish-blue.

Using food-safe techniques, the team was able to “block” this pathway at certain points, creating strains with new colors.

“We have been interested in cheese fungi for over ten years and traditionally, when developing mould-ripened cheeses, you get blue cheeses such as Stilton, Roquefort and Gorgonzola, which use fixed strains of blue-green fungi” said Dr. Said Dyer.

‘We wanted to see if we could develop new strains with new flavors and appearances.

“The way we did it was to induce sexual reproduction in the fungus, so for the first time we were able to generate a wide range of strains that had novel flavors, including new and attractive, smooth and intense flavors.

“Then we created new color versions of some of these new strains.”

While the new color versions looked impressive, one key question remained: what did they taste like?

Once the team produced the cheese with the new colored strains, they used laboratory diagnostic instruments to see what the flavor would be like.

“We found that the flavor was very similar to the original blue strains from which they were derived,” Dr. Dyer said.

“There were subtle differences, but not many.”

Volunteers from across the university tasted the cheeses, revealing some interesting impacts of the different colors.

“We found that when people tried the lighter-colored strains they thought they had a milder flavor,” Dr. Dyer said.

‘Whereas they thought the darker strain had a more intense flavour.

‘Similarly, with the redder brown and the light green, people thought they had a sour, fruity element, whereas, according to laboratory instruments, they tasted very similar.

“This shows that people perceive flavor not only by what they taste but also by what they see.”

The team will now look to work with cheesemakers in Scotland and Nottinghamshire to create new colored varieties of blue cheese.

WHEN DID PEOPLE START MAKING CHEESE?

During excavations of ancient pottery, researchers found residues of a feta-like cheese in the remains of ryton horns and strainers dating back to 5300 BC

Access to milk and cheese has been linked to the expansion of agriculture across Europe around 9,000 years ago.

The two villages, Pokrovnik and Danilo Bitinj, were occupied between 6000 and 4800 BC. C. and they have several types of ceramics throughout that period.

The residents of these villages appear to have used specific types of pottery for the production of different foods, with cheese residues being the most common in ryta and sieves.

According to the latest discoveries, cheese emerged in the Mediterranean 7,200 years ago.

Fermented dairy products were easier for Neolithic humans to store and were relatively low in lactose.

It would have been an important source of nutrition for all ages in early agricultural populations.

The authors therefore suggest that cheese production and associated ceramic technology were key factors that aided the expansion of early farmers into northern and central Europe.
