Popular questions
  1. Is calcium chloride safe?

    Yes—calcium chloride (E509) is approved for use in foods and is generally recognized as safe at typical levels; concentrated solutions can irritate the mouth or stomach, so it’s used in small, regulated amounts.

  2. Is calcium chloride bad for you?

    Not at normal food-use levels; it supplies calcium and chloride and is not considered harmful when used as intended. Large amounts or non–food-grade products (like de-icers) can cause irritation or electrolyte disturbances.

  3. Is calcium chloride safe for pets?

    In small, food-grade amounts used in pet foods it’s generally safe. Exposure to de-icing products containing calcium chloride can irritate paws and the GI tract—rinse paws and contact a vet if a pet ingests a significant amount.

  4. What is calcium chloride used for?

    In foods it’s used as a firming agent and stabilizer (e.g., in canned vegetables and pickles), a coagulant in tofu/cheese making, and to adjust mineral content in brewing and beverages. Beyond food, it’s used for de-icing and as a desiccant.

  5. What is calcium chloride in food?

    It’s a mineral salt additive (E509) used as a firming agent, stabiliser, and coagulant to help maintain texture in products like canned tomatoes, pickles, tofu, and cheese, and it can also provide electrolytes in some drinks.

  1. Is potassium alum safe?

    Yes—when used within legal limits in foods, potassium alum (E522) is permitted for limited uses and considered safe; nonetheless, total aluminum intake should stay below EFSA’s tolerable weekly intake of 1 mg/kg body weight, and people with kidney disease should be cautious.

  2. Does potassium alum contain aluminum?

    Yes; it’s a double sulfate salt (KAl(SO4)2·12H2O) that contains trivalent aluminum.

  3. Is potassium alum aluminum?

    No; it isn’t elemental aluminum but a sulfate salt that contains aluminum ions.

  4. Is potassium alum bad for you?

    Not at the small amounts allowed in foods; excessive aluminum exposure can be a concern—especially for people with impaired kidney function—so uses and levels are restricted.

  5. Is potassium alum the same as aluminum?

    No; potassium alum (aluminum potassium sulfate) is a compound containing aluminum, not the same as pure aluminum metal.
