What kind of preservatives used in idly powder?

Idly powder typically does not contain artificial preservatives, as it is made from natural ingredients like rice and urad dal (black gram). However, some commercial brands may use natural preservatives like salt or citric acid to enhance shelf life. It's essential to check the ingredient label for any specific additives or preservatives if you are purchasing packaged idly powder. Homemade versions usually do not require any preservatives and are best consumed fresh.
