While some forms of aluminum compounds, such as aluminum sulfate (E520), are approved food additives under strict regulations, consuming industrial-grade aluminum sulfate is dangerous and potentially fatal. The question "Is aluminum sulfate okay to eat?" is best answered by understanding this critical distinction between regulated food-grade uses and other hazardous forms.

In the United States, the Food and Drug Administration (FDA) lists food-grade aluminum sulfate as "generally recognized as safe" (GRAS) for use in food when following good manufacturing practices. So, why is aluminum sulfate in food, and what specific functional roles does it play in processed foods like baked goods and pickled items? This article delves into its various applications and its safety profile.
