Navigating the world of gluten-free eating can feel like a minefield, especially when you encounter sneaky ingredients like barley malt extract. If you’re a coeliac or someone with gluten sensitivity, you’re probably wondering, “How bad is barley malt extract, really?” Let’s dive into the details and clear up the confusion with friendly, easy-to-understand information.
What is Barley Malt Extract?
Barley malt extract is derived from barley and used as a seasoning agent in foods and beverages. It’s made by sprouting and malting barley grains, then processing the malt to extract sugars, proteins, and other soluble components. You’ll often find it enhancing the flavor of breakfast cereals, baked goods, sweets, non-alcoholic drinks, and even beer. It imparts a sweet, nutty taste, which is why it’s a popular ingredient.
Why is Barley Malt Extract a Concern for Coeliacs?
Here’s the crux of the issue: barley malt extract is not gluten-free. Gluten is a general name for the storage proteins found in wheat, rye, barley, and related grains. For individuals with coeliac disease or gluten sensitivity, consuming gluten can trigger adverse health effects.
Gluten Content in Barley Malt Extract
Barley malt extract contains gluten because it is derived from barley grains. While the malting process may reduce the gluten content compared to intact barley grains, it doesn’t eliminate it entirely. Testing has revealed that barley malt extracts can contain significant levels of gluten.
When three barley malt extracts were tested using the competitive R5 ELISA method, they were found to contain approximately 320, 960, and 1300 parts per million (ppm) of gluten. Even if you consider that the R5 ELISA might overestimate barley contamination, the gluten levels are still substantial. After adjusting for potential overestimation, the extracts likely contained around 160, 480, and 650 ppm of gluten.
The 20 ppm Threshold
In many regions, a product can be labeled “gluten-free” if it contains less than 20 ppm of gluten. However, this doesn’t automatically make barley malt extract-containing products safe for everyone with coeliac disease. The Coeliac UK has stopped listing products containing barley malt extract unless they are labeled gluten-free to encourage manufacturers to be more transparent and committed to gluten-free labeling.
The Tricky Issue of Testing
Testing for barley contamination in food can be challenging. Different assays have varying degrees of accuracy. For instance, the sandwich omega-gliadin ELISA can underestimate gluten from barley, while the sandwich R5 ELISA might overestimate it. When testing hydrolyzed products like barley malt extract, the test that usually overestimates might even underestimate the gluten content.
Fortunately, there’s a competitive R5 ELISA test available for testing hydrolyzed ingredients, providing a more accurate assessment.
Potential Side Effects
For those with coeliac disease or gluten sensitivity, consuming barley malt extract can lead to several unpleasant side effects:
- Bloating, gas, and abdominal discomfort
- Diarrhea, constipation, or loose stools
- Headaches and fatigue from malabsorption
- Nutrient deficiencies if consumed long-term
- Damage to the small intestine villi, increasing the risk of additional autoimmune diseases
Even if you don’t have coeliac disease, some sensitive individuals might experience digestive upset, headaches, or irregular blood sugar levels from consuming barley malt extract.
How to Navigate Food Labels
Navigating food labels is crucial for avoiding gluten. Here are some tips:
- Always check the ingredient list: Look for “barley malt extract” or any other barley-derived ingredients.
- Be cautious of “gluten-free” labels: Just because a product is labeled gluten-free doesn’t automatically mean it’s safe if it contains barley malt extract. Ensure the manufacturer has tested the product and confirms it contains less than 20 ppm of gluten.
- Contact manufacturers: If you’re unsure about a product, reach out to the manufacturer for clarification.
- Err on the side of caution: Some experts recommend avoiding gluten-containing grains altogether.
Alternatives to Barley Malt Extract
If you’re looking for gluten-free alternatives to barley malt extract, here are a few options:
- Sorghum malt extract: Made from sorghum, a gluten-free grain.
- Rice malt syrup: A sweetener derived from rice.
- Molasses: A thick, dark syrup produced during the sugar-making process.
- Honey: A natural sweetener with a distinct flavor profile.
- Maple syrup: Another natural sweetener with a unique taste.
Conclusion
In summary, barley malt extract contains gluten and poses a risk to individuals with coeliac disease or gluten sensitivity. It’s essential to read labels carefully, seek clarification from manufacturers, and consider gluten-free alternatives to ensure your diet remains safe and symptom-free.
