Calcium Lactate Storage — Calcium Salt of Lactic Acid Tank Selection

Storing Calcium Lactate? Start Here

Calcium lactate is a versatile calcium salt often used in food, pharmaceuticals, and agriculture. It's a white, crystalline powder that's pH-neutral to mildly alkaline when dissolved in water. This makes it a popular choice for calcium fortification in foods and supplements, as well as for preserving the firmness of fresh produce. If you're considering storing calcium lactate, here's what you need to know about tank options and safety.

Can you store it in a poly tank?

Yes, you can store calcium lactate in a polyethylene (poly) tank. HDPE and XLPE are both suitable for storing calcium lactate solutions, making them a cost-effective choice for food-grade and technical-grade storage. Just ensure that the tank meets FDA standards for food contact.

Key Issue: Temperature Sensitivity

While calcium lactate is stable, its solubility increases with temperature. This means that if you're storing a solution, maintaining a consistent temperature is important to prevent crystallization or precipitation. Ensure your storage environment is controlled to keep the solution stable.

The safety that actually matters

• Use FDA-approved materials for any food or pharmaceutical applications.
• Ensure proper ventilation to avoid dust accumulation when handling the powder.
• Regularly inspect tanks and fittings for wear and tear to maintain integrity.

Common questions

Can I use stainless steel tanks?

Yes, 316L stainless steel is preferred for pharmaceutical and food applications due to its durability and cleanliness.

What gasket material should I use?

EPDM gaskets are standard for food-grade applications, but always check compatibility with the manufacturer's chart.

Is calcium lactate safe for food use?

Yes, it's Generally Recognized as Safe (GRAS) by the FDA for use in food products.
