If you bake a lot with yeast and keep it on hand, pay close attention to the expiration dates and store it in the refrigerator or freezer to increase its shelf life. Be sure to bring it to room temperature before using it. Sign in.

I'm sure you may have noticed this site hasn't been updated in about a year. In case you weren't aware, Vegan Pesto Potato Salad February 22, By itself, xanthan drastically increases the viscosity thickness of any liquid it is added to in very low concentrations.
In high concentrations, it will form a mucusy paste that looks like a gel but is not technically a gel. It does, however, form a gel when combined with locust bean gum. Xanthan gum's real benefits come through its interactions with other ingredients. By increasing the viscosity of liquids, it helps to prevent syneresis weeping in gels, keep ice crystals from forming in frozen goods, and help stabilize emulsions and foams.
Xanthan is a popular ingredient in gluten-free foods because it can impart some of the texture that gluten gives to baked goods. Xanthan Gum has been used by molecular gastronomy Chef Ferran Adria to suspend solids in liquids thanks to its elasticity in his famous "Melon with Ham" dish introduced at elBulli in This dish consisted of a clear ham consomme with suspended melon caviar spheres. He does this at the winery by introducing Xanthan Gum after the first fermentation of Cava and then let it continue the process for nine months.
This results in carbonated cava sauce which he uses in this oyster dish. Spherical olives are a classic molecular gastronomy application by chef Ferran Adria and the el Bulli team. It's also one of the early examples of reverse spherification. In this application, xanthan gum is used to thicken the olive juice in encased in the spheres. Guilbert, Macromol. Rosell, A.

The additive is used primarily as a food thickener agent or stabilizer.
It is a highly water soluble large molecule and gives a thick solution in small quantities. Increasing viscosity of liquid. Keeping emulsions homogenized and particles suspended for long periods. Stabilization of oil soluble flavours in water based beverages. Valued for its ability to withstand a range of temperature and pH. Due to its heat stability it is used in canning and pasteurized products. Due to its shear thinning character xanthan is used in salad dressings; meaning that at high shear its viscosity drops and under low shear it keeps its viscosity.
In gluten-free baking, xanthan reinforces gluten-free flour mixtures by adding "stickiness". Excessive xanthan will create an undesirable "snotty" texture. This can be overcome by using it in combination with guar gum obtained from guar beans. Xanthan hydrates quickly at all temperatures, so it has a strong tendency to clump.
One popular dispersion method is to disperse in oil either on a or ratio of xanthan to oil followed by vigorously whisking and, optionally, straining to remove any remaining clumps.
Another method is to thoroughly mix xanthan with a small amount of sugar, preferably in a mortar, prior to dispersion. This delays the hydration enough to allow the gum to disperse before it has a chance to form lumps.
