Questions And Answer

• Chemical properties

  Calcium acetate, also known as acetate of lime or vinegar salts, is the calcium salt of acetic acid. It is an odorless powder. Calcium has an important role in the nutrition of humans and animals. Hormonal mechanisms control absorption of dietary calcium (including added calcium salts) allowing adaptation to a range of calcium intakes while maintaining a relatively constant blood calcium concentration of about 10 mg/100 mL. Major functions of calcium inside the body include the formation and maintenance of bones and teeth, the physiology of muscle contraction, the cell membrane integrity, the activity of several enzymes that have specific requirement for it, the coagulation of blood, and the regulation of acid-base balance.* ;

• Uses

  Calcium acetate [Ca(CH3COO)2.H2O] is used as a food additive and a mordant to fix dyes in the textile industry. It is used as an alkali (base) in the manufacture of soaps, to improve some lubricants, and as an antimold to preserve baked goods for a longer shelf life. ;

• Toxicity

  ADI is not subject to restrictive regulations (FAO/WHO, 2001).
  GRAS (FDA, §181.29, §182.6197, § 184.1185, 2000).
  LD50: 52 mg/kg (mouse, subcutaneous).;

• Usage limit

  GB 14880 a 94: cereals and their products, beverages 8~16g/kg.
  GB 2760-2001: vinegar, 6~8g/kg (in terms of Ca).
  FAO/WHO (1984): Edible caseinate, GMP.
  FDA, § 184.1185 (2000): baked goods, gelatin, pudding, fillings, 0.2%; sweet sauce, top materials and poured, 0.15%;
  EEC can be used for packaging cheese powder, quick-setting jelly powder.
  FEMA (mg/kg): soft drinks 200; baked goods 500.;

• Production method

  It is obtained by the reaction between calcium carbonate and acetic acid. Preparation method of anhydrous calcium acetate: the refined powder of calcium carbonate is added to the water, stirred into a suspension; added separately of a small amount of glacial acetic acid. After completion of the reaction, the filtrate was concentrated in a water bath and a white solid, anhydrous calcium acetate, was precipitated from the viscous filtrate.
  It is obtained by the neutralization between coke acid (wood acetic acid) and calcium hydroxide, followed by the evaporation of the filtrate and recrystallization.
  It is obtained by the reaction between the reaction between acetic acid and calcium hydroxide or calcium carbonate. Filter, concentrate and cool to obtain the dihydrate (colorless crystal), heated to 84 °C in a water salt (colorless crystal), heated to 100 °C to obtain the anhydrous salt.
  Shellfish can be taken as raw materials, washed, crushed and dried for 1 h, subjecting to barbecue for 2 hour at 900~l000 ℃, then being added water to make a 1.3~1.5mol/L lime milk. And then neutralized with acetic acid to clarify, filter with the filtrate concentrated, and finally dried at 120~140 °C to get the final product with a yield of 91.28%.
  To a 20% acetic acid solution, add calcium carbonate powder to until there is no longer any CO2 gas escaping, then add a small amount of calcium carbonate, heated  80 ° C for reaction of 2-3h. The filtrate was heated and concentrated with water bath while adding a small amount of 80% acetic acid at the same time to precipitate the calcium acetate monohydrate (what precipitated after the cooling of the solution is dihydrate), and finally dried at 60~70 ℃to derive the products.;
