Have you ever wondered how rennet, a key ingredient in the traditional cheese-making process, is actually obtained? The answer lies in the stomach lining of young mammals, which contains a special enzyme called chymosin. In this blog post, we will take a closer look at how rennet is extracted from the stomach, specifically exploring the fascinating process of obtaining caglio, the Italian term for rennet.

What is Caglio?

Caglio is a natural enzyme complex derived from the stomach lining of young animals, such as calves, kids, and lambs. It is an essential ingredient in the coagulation process of cheese-making. When added to milk, caglio helps precipitate the milk proteins, forming curds and separating them from the liquid whey.

How is Caglio Extracted?

The extraction of caglio involves several steps to ensure purity and effectiveness. Here is a breakdown of the process:

  • Selection: Only young, healthy animals are chosen for caglio extraction. Their stomachs are considered the richest source of the chymosin enzyme.
  • Harvesting: After the animals are humanely slaughtered for meat production, their stomachs are collected for further processing.
  • Cleaning: The collected stomachs are carefully cleaned to remove any impurities and to prepare them for enzymatic extraction.
  • Preparation: The cleaned stomachs are then processed to separate the individual layers. The innermost layer, known as the abomasum or rennet pouch, is the main source of chymosin and is used for caglio extraction.
  • Enzymatic Extraction: The abomasum is cut into small pieces and immersed in a solution to release the chymosin enzymes. This process allows the extraction of rennet from the stomach.
  • Filtration and Purification: The extracted solution is filtered and purified to remove any impurities and obtain a highly concentrated and pure form of caglio.

Usage of Caglio in Cheese-making

Once the caglio is extracted and purified, it can be used in the cheese-making process. Here's a brief overview of how caglio is used:

  1. Preparation: The desired quantity of caglio is added to fresh milk.
  2. Coagulation: The caglio initiates the coagulation process by causing the milk proteins to form curds.
  3. Curding: Within a specific time frame, the milk is left undisturbed to let the curds form and separate from the liquid whey.
  4. Cutting and Stirring: The formed curds are cut into small pieces, allowing the whey to drain. This is followed by gentle stirring to encourage proper drainage and further expel whey.
  5. Molding and Pressing: The curds are then placed in molds and pressed to compact them, resulting in the desired shape and texture of the cheese.
  6. Ripening: Finally, the cheese is left to ripen, developing its distinct flavors and textures over time.

In Conclusion

The extraction of rennet from the stomach, specifically caglio, plays a vital role in the traditional cheese-making process. By carefully obtaining and using caglio, cheese artisans are able to create a wide variety of delicious and unique cheeses. It is this attention to detail and time-honored techniques that contribute to the rich history and artistry of cheese-making.
