Tapioca starch is a type of starch extracted from the cassava root. It is a fine, white powder that is commonly used as a thickening agent in a variety of foods and beverages, including soups, sauces, and desserts. Tapioca starch is a gluten-free and grain-free alternative to wheat flour and other thickeners, making it a popular choice for those with celiac disease or gluten sensitivities.
In protein powders, tapioca starch is often used as a filler or stabilizer to help improve the texture and mouthfeel of the product. It can also be used to help prevent clumping and improve mixability. Tapioca starch is generally considered safe to consume and is not associated with any major health concerns.
