Ultra-Tex is a modified corn or tapioca starch that is very similar in use to xanthan gum. Ultra-Tex starch is often used to thicken liquids without having to boil them, giving the finished liquid a mouth feel similar to one thickened with cornstarch or flour, but still preserving its raw color and flavor. When higher concentrations of thickener are required, Ultra-Tex is a better choice than xanthan gum.
There are several different kinds of Ultra-Tex that are modified in different ways. The most popular are Ultra-Tex 4 which is made from corn and Ultra-Tex 8 which is made from tapioca starch.
