What 'Black Magic' goes into making Marmite? | Food Unwrapped
TLDRThe video script provides an insightful journey into the world of yeast extract production. The narrative follows a curious individual's quest to understand the mysterious flavor of yeast extract, leading them to Burton-upon-Trent, Staffordshire, home to one of Britain's finest factories. Here, they meet Sinjin Skelton, a quality specialist, who guides them through the process. The yeast, sourced from breweries, undergoes a transformation in large coppers, where it's heated to break down cell walls. After centrifugation, the yeast is concentrated and then blended with secret ingredients, including barley, salt, vegetable juice concentrate, and celery, to create the distinctive taste. The factory, with its 25 million jars produced annually, is a testament to the enduring appeal of this unique ingredient, despite its divisive flavor profile.
Takeaways
- 🧫 Yeast extract is made from yeast cells that multiply during the beer brewing process, producing a surplus of yeast that is then used for the extract.
- 🏭 The yeast is sourced from breweries and arrives at the factory in large quantities, where it is processed further.
- 🌡️ The yeast is heated to 95 degrees Celsius in coppers, which kills the live yeast and breaks down their cell walls.
- 🔄 A centrifuge is used to separate the broken-down cell walls from the cell innards, resulting in a yeasty liquid.
- 🧂 The yeast extract is concentrated and then combined with six secret ingredients, including barley, salt, vegetable juice concentrate, and celery.
- 🔴 The final product has a distinct red color and a unique taste, which some people grow to love.
- 🔍 The quality specialist, Sinjin Skelton, is responsible for ensuring the product meets high standards.
- 🏗️ The factory has been operating since 1902 and is considered one of Britain's finest for producing yeast extract.
- 🚜 Large equipment, such as coppers and centrifuges, are essential for processing the yeast into extract.
- 📦 The final product fills 25 million jars a year, indicating the significant scale of production.
- 👨🔬 Steve Jones, the lead operator in production, confirms that taste testing is a part of the job, suggesting that workers are familiar with the flavor profile of the yeast extract.

🧪 Yeast Extract Production Process
The video script introduces the process of making yeast extract, starting with a discussion about the product's taste and its appeal to different individuals. The narrator, Jim, travels to Burton-upon-Trent in Staffordshire to explore the secrets behind a specific brand of yeast extract. The yeast used in the extract comes from breweries, where it is a byproduct of beer production. The yeast cells multiply as they convert sugar into alcohol, resulting in a surplus that is sold to make yeast extracts. Upon arrival at the factory, the yeast is heated to 95 degrees Celsius in large containers called coppers, which kills the yeast and breaks down their cell walls. The mixture is then centrifuged to separate the broken cell walls from the cell contents. This 'yeasty soup' is concentrated and combined with six secret ingredients, including barley salt, vegetable juice concentrate, and celery, to create the final product. The factory fills 25 million jars a year, and the lead operator, Steve Jones, confirms that everyone at the factory enjoys the taste of the yeast extract.
