In gluten-free baking, binders are the unsung heroes. They replicate the structure and elasticity gluten provides, ensuring your loaves rise, hold their shape, and don’t crumble into dust. Over the years I’ve tested many options—each brings unique strengths and quirks.
Here’s what I’ve learned about xanthan gum, psyllium husk, and other popular gluten-free binders, plus tips on when (and when not) to use them, how much to use, and what the science says.
Why Are Binders Essential in Gluten-Free Baking?
Gluten, a protein found in wheat, rye, and barley, gives dough elasticity and traps gas from fermentation, helping bread rise. Without gluten, baked goods can be dry, dense, or crumbly. Binders mimic these structural properties by holding ingredients together, retaining moisture, and improving texture.
Most gluten-free flours lack binding ability. Without a good binder, your dough won't trap air or develop structure—key elements particularly important in bread making.
Xanthan Gum: A Double-Edged Sword
Xanthan gum is a polysaccharide produced by fermenting sugar with Xanthomonas campestris bacteria. It's widely used in commercial and home gluten-free baking for its strong thickening and stabilizing properties (PubChem, NIH).
Texture: Elastic, chewy.
Best For: Cakes, cookies, muffins, quick breads.
Typical Use: ½ tsp per cup of flour.
Scaling Tip: When baking more than one loaf of bread, reduce by ¼–½ tsp per additional loaf to avoid gumminess.
Baking Tip: Avoid double-rising—xanthan’s structure is fragile and can collapse in the oven.
Health Note: Some people experience digestive discomfort from large amounts of xanthan gum. Stick to recommended amounts.
Psyllium Husk: Dough Made Easy
Psyllium husk is derived from the seeds of Plantago ovata and is rich in soluble fiber. It absorbs water to form a gel, improving dough elasticity and moisture retention (Journal of Food Science and Technology, 2022).
Texture: Pliable, soft.
Best For: Sandwich loaves, yeast breads.
Typical Use: 1 tbsp psyllium husk powder per cup of flour (7g per 120g flour).
Color Note: Psyllium can darken the dough—choose based on visual preferences.
Bonus: May improve digestion and help control blood sugar.
Guar Gum: The Gentle Binder
Guar gum, extracted from guar beans, is high in soluble fiber and works similarly to xanthan but yields a softer texture. It’s a good alternative if you're sensitive to xanthan.
Texture: Soft, smooth.
Best For: Breads, pastries.
Typical Use: ¼ to ½ tsp per cup of flour.
Health Note: Less likely to cause sensitivity, but still use moderately.
Natural Binders: Chia and Flaxseed
These seeds form a gel when mixed with water and are often used as egg replacers. While nutritious, they don’t offer the same strength as gums especially for gluten free bread.
Texture: Fibrous, slightly gritty.
Best For: Cakes, muffins, cookies, vegan baking.
Typical Use: 1 tbsp chia/flax + 3 tbsp water = 1 egg.
Bonus: High in omega-3s and fiber.
Special Note: Though it is a common suggestion to use chia and flaxseed as egg replacers in cakes and muffins, it is not something that I gravitate to. In my experience, replacing eggs successfully requires more than just swapping in chia and flaxseed—it often demands adjusting the entire recipe. This includes a slight increase in the amount of flour or starch used, adding additional moisture such as milk or a milk alternative, and incorporating extra leavening (e.g., baking powder) paired with an acid like vinegar. Without these changes, the final product may lack the volume, tenderness, and rise typically provided by eggs.
Scientific studies support this need for adjustment. According to research published in Food Chemistry (2018), while flax and chia gels can partially replicate the emulsifying and binding roles of eggs, they fall short in foaming and leavening, which are crucial in baked products where eggs contribute significantly to structure and aeration. As such, simply substituting without formulation tweaks often leads to dense or gummy textures.
Other Binders: Gelatin, Agar-Agar & Egg Whites
Gelatin (animal-based): Adds moisture and structure to cakes and rolls.
Agar-Agar (plant-based): Vegan alternative to gelatin, less elastic.
Egg Whites: Provide both structure and leavening—great for light cakes and muffins.
How Much Binder Should You Use?
Binder | Typical Use (per cup of GF flour) |
Xanthan Gum | ½ tsp |
Guar Gum | ¼–½ tsp |
Psyllium Husk Powder | 1 tbsp (7g) |
Flax/Chia | 1 tbsp seed + 3 tbsp water = 1 egg |
Always test in small batches before scaling up. Overusing binders can lead to gumminess, toughness, or a dense crumb.
Other Uses for Binders
Xanthan/Gaur Gum: Common in salad dressings, sauces, and ice cream as stabilizers.
Psyllium: Used as a fiber supplement (e.g., Metamucil).
Chia/Flax: Popular in smoothies and breakfast bowls.
Final Thoughts
Choosing the right binder can make or break your gluten-free bakes. Each type has its own characteristics, and your choice will depend on the recipe, desired texture, and dietary needs. For bread, I swear by psyllium. For everything else, xanthan remains my favorite.
