GB 1895-1994

This standard specifies the technical requirements, test methods, inspection rules, and packaging, labeling, storage, and transportation conditions for aluminum potassium sulfate (potassium alum) used as a food additive. It is applied in the food industry, particularly for products like fried dough sticks, vermicelli, and pickled vegetables, where the compound serves as a leavening agent, firming agent, or buffer. The standard ensures the purity and safety of the additive, limiting aluminum residue to comply with food safety regulations.
