Due to the relative high cost of wheat starch, alternative sources were identified and this gave rise to the development of the potato starch industry in the 18th century. Potato starch is a very refined starch, containing minimal protein or fat, which gives the powder a clear white color. And in terms of its nutritional benefits, this starch has been shown to be helpful to blood sugar regulation. It is worth noting that starch derivatives are used in many recipes, such as in noodles, potato chips, hot dog sausages, bakery cream and instant soups and sauces. In pastry, e.g. sponge cake, this powder is used to keep the cake moist, and gives it a soft texture.
