Calcium lactate is a salt composed of two lactate anions for every calcium cation (Ca2+). It's created commercially by neutralizing lactic acid with either calcium carbonate or calcium hydroxide.
Here's a breakdown:
- Composition: Calcium lactate is a calcium salt of lactic acid. This means it combines calcium ions with lactate ions.
- Production: It is typically manufactured by reacting lactic acid with a calcium-containing base, such as calcium carbonate (limestone) or calcium hydroxide (slaked lime). This process neutralizes the acid, forming calcium lactate and water.
- Appearance: Calcium lactate is usually a white, odorless powder or granules.
- Solubility: It is soluble in water, although not as soluble as some other calcium salts. Solubility increases with temperature.
Uses of Calcium Lactate
Calcium lactate has various applications, including:
-
Medicine:
- As a calcium supplement to treat or prevent calcium deficiencies.
- To control high phosphate levels in the blood (hyperphosphatemia), especially in people with kidney disease.
-
Food Industry:
- As a food additive (E327).
- As a firming agent in canned fruits and vegetables. It reacts with pectin to create a firmer texture.
- As a leavening agent ingredient.
- As a source of calcium enrichment in foods.
-
Other Applications:
- In some dentifrices (toothpastes).
Important Considerations
While calcium lactate is generally considered safe, it's essential to be aware of the following:
- Dosage: Follow the recommended dosage when using calcium lactate supplements.
- Side Effects: Possible side effects include nausea, vomiting, constipation, and dry mouth.
- Interactions: Calcium can interact with certain medications, such as some antibiotics and thyroid medications. Consult a healthcare professional before using calcium lactate if you are taking other medications.
- Hypercalcemia: Excessive intake of calcium can lead to hypercalcemia (high levels of calcium in the blood), which can cause various health problems.
In conclusion, calcium lactate is a calcium salt used as a supplement, food additive, and medication. It's manufactured by neutralizing lactic acid with a calcium base and plays a crucial role in various industries.
