Comparing E509 - Calcium chloride vs E263 - Calcium acetate

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.

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.

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.

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.

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.
