Xanthan gum and guar gum both thicken, but neither does psyllium’s job of forming a gel that holds a dough together. Xanthan is shear-thinning: thick at rest, thinner when stirred or worked, even at very low concentration. Guar builds viscous solutions with comparatively little gelling strength of its own, so it thickens a liquid without…
Soluble fiber dissolves in water and can form a gel; insoluble fiber doesn’t dissolve, and mainly adds bulk. In keto flours that split predicts which one can bind and which one only holds water. Psyllium husk’s fiber is mostly soluble, coconut flour’s is mostly insoluble, and flaxseed sits in between. This post sits in the…
Flaxseed mucilage is the gel that forms when ground flaxseed meets water, and it’s why a “flax egg” (ground flaxseed stirred into water) can bind a batter. It comes from the seed’s outermost layer and is made of two different polysaccharides (long chains of sugar units) plus some protein. That makes it a functional cousin…
Almond flour can’t build a dough network because its proteins come from the wrong families. Wheat’s gluten is built from a prolamin and a glutelin, while almond protein is overwhelmingly globulin and albumin, with very little glutelin and next to no prolamin. On top of that, almond flour carries a lot of fat, and fat…
Coconut flour drinks so much water because it’s mostly fiber, and fiber holds water. One composition study measured 46.39 g of total dietary fiber per 100 g in a partially defatted coconut flour, against 2.37 g per 100 g in the refined wheat flour tested alongside it, and the researchers tied coconut flour’s higher water-holding…
Gluten is a network that two wheat proteins build together: gliadin lets dough stretch and flow, and glutenin makes it spring back. What holds that network together is a set of chemical bridges between glutenin molecules, and no single ingredient has been found that fully replaces it. That’s why gluten-free doughs lean on hydrocolloids, which…
Why Psyllium Husk Gels Back in “Why Traditional Chaat Breaks Keto,” we named the job maida is doing: gluten formation gives dough the elasticity to roll thin and the structure to blister and crack in hot oil. We also flagged that nothing fully replaces that job — that’s its own post, coming up. But psyllium…
