VIDEO How they saved the holes in Swiss cheese

How Swiss Cheese Holes Are Being Saved In a fascinating exploration of the science behind Swiss cheese, a recent YouTube video titled How they saved the holes in Swiss cheese details the intriguing journey of preserving the holes, or "eyes," in Swiss cheese, which have been diminishing in recent decades.

The Historical Background​

For nearly a century, the popular belief held that the holes in Swiss cheese resulted from carbon dioxide produced during the fermentation process. However, a concerning trend emerged around 30 years ago: cheese makers began observing that these holes were becoming smaller and less frequent. This prompted scientists, particularly those at Agroscope—Switzerland's government-backed agricultural research facility—to investigate the root cause of this phenomenon.

The Role of Bacteria​

Agroscope is known for its extensive collection of cheese samples and the bacteria responsible for making it. The facility focuses on preserving unique bacterial strains that contribute to the characteristic features of Swiss cheese. With around 15,000 bacteria isolates, the lab is tasked with understanding the genome and behavior of these microbes better. Each cheese has its own unique bacterial culture, a vital factor in the cheese-making process. As the video explains, the bacteria produce essential gases and acids during fermentation, which contribute to the formation of holes in the cheese.

Modern Challenges​

With advancements in hygiene and food safety standards, including the adoption of closed milking systems, the quality of milk has improved considerably, leading to cleaner milk devoid of impurities. While this was beneficial for food safety, it created a new challenge—the absence of small dust particles that historically aided in the hole formation. Agroscope's researchers experimented with different materials to introduce back into the milk to see if they could revive the process of hole formation. They found that adding hay powder had a significant impact, with only one milligram needed per thousand liters of milk to encourage the return of holes in the cheese.

Implications for Swiss Cheese Industry​

This research is not just an academic exercise but is crucial for the Swiss cheese industry. The holes in cheese are not simply aesthetic; they play a significant role in the cheese's identity and marketability. The video emphasizes that there are legal protections for certain cheese types, ensuring that only cheese produced with specific bacterial strains can be labeled under Swiss cheese. Furthermore, with the rise of cheese fraud, where cheaper imitation products are sold, maintaining the integrity of authentic Swiss cheese is vital for consumers and producers alike.

Conclusion​

The pursuit of maintaining the traditional features of Swiss cheese, particularly its holes, highlights the intersection between food science and cultural heritage. As the experts at Agroscope continue their work, they not only aim to preserve the unique characteristics of Swiss cheese but also to bolster the industry against challenges posed by modernization and globalization.
