What is it?
Hydrochloric acid is a strong inorganic acid used mainly as a processing aid and acidity regulator in the food industry. It adjusts pH, hydrolyses starch, inverts sucrose and produces acid-hydrolysed proteins.

In a nutshell
Hydrochloric acid is used chiefly as a processing aid and acidity regulator for hydrolysis, inversion and pH control.
Consumer Advice
Food-grade hydrochloric acid is used in processing as an acidity regulator and in processes such as protein hydrolysis. Residual amounts in finished foods are tiny, and the human stomach produces hydrochloric acid naturally, so the body handles it with ease. It is safe when used to food-grade standards, and consumers never encounter it in its concentrated form in food.
