Potato starch contains typical large oval spherical granules ranging in size from 5 to 100 μm. Potato starch is a refined starch, containing minimal protein or fat. This gives the powder a clear white colour, and the cooked starch typical characteristics of neutral taste, good clarity, high binding strength, long texture, and minimal tendency to foaming or yellowing of the solution.

Potatoes, and other starchy foods, actually contain a special type of starch, called resistant starch which isn't digested by your body. It's “resistant” because it can't be broken down by the digestive enzymes produced by your body, so it travels all the way to your large intestine where it feeds your gut microbiome.

The starch content of a potato can be highly variable. In general terms fresh potatoes contain ~20% dry matter (DM) of which 60–80% is starch, with 70–80% of this starch as amylopectin [23].

Starch is obtained from various source such as maize, rice, potato, wheat, etc. These starch are insoluble in water but soluble in hot water.
