Alum is a double salt that hydrolyzes to become acidic, while alkali (edible alkali) is a carbonate that hydrolyzes to alkaline water content and crystallizes water. When alum and alkali are put into water, chemical changes will occur between them, producing a large amount of carbon dioxide gas and floc aluminum hydroxide. When combined with the surface, the floc aluminum hydroxide and the surface form a film to enclose the carbon dioxide gas. When the fried dough sticks are put into the hot oil pan, the carbon dioxide gas heats up and expands, causing the fried dough sticks to expand. This is why alum and alkali are added to fried dough sticks. Alum contains aluminum. Long-term or large consumption of alum can lead to aluminum poisoning and even induce Alzheimer's disease.
