Application:
1. Medical field (the most important and highly specialized application)
Treatment of hyperphosphatemia (in patients with kidney disease) :
Core application: This is the most important and unique application of calcium acetate. It is mainly used for patients with chronic kidney disease (CKD) undergoing dialysis treatment, especially those with end-stage renal disease (ESRD).
Mechanism of action: When patients have renal failure, they are unable to effectively excrete phosphorus, resulting in excessive phosphorus content in the blood (hyperphosphatemia). Hyperphosphatemia can cause serious complications such as secondary hyperparathyroidism, renal osteopathy and vascular calcification.
Phosphate binder: Calcium acetate combines with phosphate (PO4 ³-) in food in the gastrointestinal tract to form insoluble calcium phosphate (Ca3(PO4)2), which prevents phosphorus from being absorbed by the intestine and thereby reduces serum phosphorus levels.
Advantages:
High calcium content: Each gram of calcium acetate provides approximately 253mg (or 25.3%) of elemental calcium, serving as a binder while also providing calcium supplementation.
Binding efficiency: At the equivalent calcium dose, its ability to bind phosphorus is comparable to or slightly better than that of calcium carbonate.
Good solubility: It is more soluble than calcium carbonate and may take effect faster.
Aluminum-free: It avoids the neurotoxicity and bone toxicity risks of aluminum salt binders (such as aluminum hydroxide).
Dosage form: Usually oral tablets or capsules (such as 667mg one tablet, containing 169mg of elemental calcium), should be taken with meals to combine with phosphorus in food.
2. Food industry
Calcium acetate, as a food additive (INS 263, E263), mainly plays the following roles:
Curing agent/coagulant
Hardening of vegetables and fruits: Added to canned or pickled vegetables and fruits (such as diced tomatoes, mixed vegetables, apple slices, olives), it reacts with pectinic acid in plant tissues to form calcium pectinate, which helps maintain the hardness and crispness of the fruit and vegetable blocks and prevents them from becoming soft and mushy during processing and storage. This is one of its most common applications in food.
Calcium fortifier
Nutritionally fortified foods/beverages: Add to bread, grains, plant-based milk (soy milk, almond milk), fruit juice, sports drinks, etc., as a bioavailable calcium source to supplement dietary calcium. It has good solubility and is easy to add.
Acidity regulator
By taking advantage of its buffering capacity, it helps maintain or regulate the pH value of the food system.
Dough conditioner
In some baked goods, it may be used to affect the properties of gluten or the activity of yeast (but not as commonly as other calcium salts such as calcium sulfate/gypsum in tofu or bread).
Anti-corrosion auxiliary agent:
At low concentrations, the weakly acidic environment it generates may have a slight auxiliary effect on inhibiting certain microorganisms, but this is not its main function (propionate, benzoate and sorbate are the main preservatives).
3. Industrial applications
De-icing agent
It is used as an environmentally friendly de-icing and de-icing agent (often mixed with magnesium acetate and potassium acetate or used alone). Compared with traditional sodium chloride (rock salt), its advantages include:
Low corrosiveness: Its corrosiveness to concrete, metals (such as Bridges and steel bars), and vehicles is much lower than that of chlorides.
The effect of lowering the freezing point is better: it remains effective at lower temperatures (as low as approximately -29°C).
Biodegradability: Acetate ions can be degraded by microorganisms.
Concrete additive
As a component of a setting accelerator or antifreeze agent, it accelerates the early strength development of concrete during construction in cold weather and prevents freezing.
Textile printing and dyeing
Used as a mordant (to help dyes adhere to fibers) or a component of certain dyes.
Laboratory reagents:
Used for chemical analysis or synthesis.
Production of cellulose acetate
As a buffer or catalyst in the reaction.
