Potato Flour and Potato Starch
Many people confuse the products potato flour and potato starch due to their similar origin and identical consistency. But the difference between them is significant.
Potato starch is produced only from the starch in the potato tubers. It makes the mixture it is added to thicker and very closely resembling wheat flour.
Potato flour is made from boiled and dried potatoes, including their peels, and is used as a thickener because it increases its moisture only when added to a particular mixture, increasing its volume.
Potato flour feels heavier than potato starch and when added to a dish it makes it taste and smell like a potato, while potato starch does not have a specific aroma.
Potato starch thickens a mixture with less of it added in comparison to potato flour, which requires greater amounts to thicken a mixture.
Potato starch must not be boiled because it loses its ability to thicken a mixture.
Storing Potato Flour
Potato flour needs to be stored in a dry place away from direct sunlight, preferably in the fridge. The flour is extremely vulnerable in a humid environment or environment where it is predisposed to attacks from insects and spoils easily in such conditions.
After opening the package, the flour must be used within 6 months because if it sits longer its taste qualities are ruined.
