To remove gluten from beer, brewers can use enzymes during the brewing process. These enzymes work by breaking down the gluten proteins into smaller fragments, which are then considered safe for consumption by those with Celiac Disease or gluten intolerance.
One commonly used enzyme is Clarity Ferm, which is a product developed by White Labs. It contains a protease enzyme derived from Aspergillus niger, a fungus commonly used in the food industry. This enzyme specifically targets the gluten proteins in beer and breaks them down into smaller, harmless fragments. Clarity Ferm is typically added during fermentation and is effective at reducing gluten levels in the final product.
Another enzyme that can be used is Brewers Clarex™, a product developed by DSM. It contains a combination of two enzymes, a proline-specific endoprotease and a hordeum vulgare cysteine endoprotease. These enzymes work together to break down the gluten proteins in beer. Brewers Clarex™ is also added during fermentation and is claimed to reduce gluten levels to below the FDA’s threshold for gluten-free products.
It’s important to note that while these enzymes can significantly reduce gluten levels in beer, they may not completely eliminate it. The effectiveness of these enzymes can vary depending on factors such as the type of beer, the brewing process, and the specific enzyme used. Additionally, there is still ongoing debate and research regarding the safety of gluten-reduced beers for individuals with Celiac Disease.
It’s worth mentioning that not all brewers use these enzymes, and some may choose to produce gluten-free beers instead. Gluten-free beers are brewed using alternative grains such as sorghum, millet, rice, or corn, which naturally do not contain gluten. These beers are typically labeled as gluten-free and are suitable for individuals with Celiac Disease or gluten intolerance.
Enzymes such as Clarity Ferm and Brewers Clarex™ can be used in the brewing process to reduce gluten levels in beer. These enzymes break down the gluten proteins, making them less harmful to individuals with Celiac Disease. However, it’s important to understand that the effectiveness of these enzymes can vary, and there is still ongoing discussion about the safety of gluten-reduced beers for those with Celiac Disease.
