PROBLEM TO BE SOLVED: To provide a food additive having low dusting characteristics and excellent flowability.SOLUTION: The food additive includes calcium acetate powder having an average particle diameter of 100 &mum to 200 &mum, of which 10 mass% aqueous solution has a pH(25°C) of 6.0 to 8.5 and an acetic acid concentration (C) of 20 ppm. When the calcium acetate powder is pulverized into fine powder having an average particle diameter of 45 &mum to 55 &mum, the acetic acid concentration is (C+0.2) ppm or more.
