What is Marmite made from? Factory shares yeast extract ingredients and processes

In an unearthed episode of Food Unwrapped on Channel 4, presenter Kate Quilton visited a Staffordshire factory to see how marmite and other yeast extracts are made.

On the streets, several members of the public tried to guess what Marmite was made of. One suggested, “A really reduced beef broth,” while another wondered if “mold and salt” went into the yeast product.

Sinjin Skelton, a quality specialist at the factory, showed Kate the whole process and revealed the ingredients.

He said: “When breweries make beer, they take a sugary solution, add yeast, and the yeast converts the sugar into alcohol.

“The yeast cells multiply as alcohol is made, and as a result, the breweries have seven times more yeast than when they started, which is then sold to make yeast extract.”

Kate remarked, “That explains the smell — it smells like beer!”

“When it comes out of the breweries, it’s pumped into big kegs called coppers,” she told viewers.

Sinjin added, “What happens there is that we adjust the temperature so that the yeast starts to break down.

“The coppers are heated to 95 degrees, which kills the live yeast and destroys the cell walls.

“The yeast soup is then separated into two liquids – the broken cell walls and the cell interior.”

Holding a bottle with the liquid, Kate remarked, “They gutted every single yeast cell, and that’s yeast extract.”

But to turn it into a spreadable product, the liquid is heated and boiled, creating a concentrated yeast extract.

Kate tasted the product after it had been cooked and said it “tasted slightly, like something was missing”. Sinjin replied, “We add secret ingredients.”

The presenter wanted to look into the large container, but was not allowed to, but commented on the color: “It’s very red!”

According to the Marmite label, it contains barley, salt, vegetable juice, concentrate and celery.

“Whatever it is,” Kate remarked. “It mixes with the yeast extract and fills 25 million jars a year.”

Marmite fans took to social media to comment on the product’s process.

“Oh god, I can’t eat this anymore. But my childhood!” one wrote.

“So basically it’s dehydrated yeast casings mixed with vegetable broth,” commented another.

A third wrote: “Toast, marmite and beer. A yeasty start to the day.”

Marmite has expanded its range to include crunchy peanut butter, truffles and chili.
