Tartaric Acid Storage — 2,3-Dihydroxysuccinic Acid Tank Selection

Storing Tartaric Acid? Start Here

Tartaric acid is a versatile compound used in winemaking, food, and pharmaceuticals. It's a white crystalline acid, often found in grape products, and is known for its role in adjusting acidity in wines and as a food additive. When storing tartaric acid, especially in liquid form, it's crucial to choose the right type of tank to ensure safety and maintain the integrity of the acid.

Can you store it in a poly tank?

Yes, tartaric acid can be stored in polyethylene tanks. Both solid and aqueous solutions of tartaric acid are compatible with HDPE and XLPE tanks, making them a standard choice for food-grade storage. Ensure that fittings and gaskets are also compatible, with polypropylene and EPDM being standard options.

Watch Out for Metal Contamination

When handling tartaric acid, avoid using copper, brass, or galvanized steel components. These metals can react with the acid, leading to contamination through metal mobilization. Always verify that any soldered joints are lead-free to prevent lead contamination, particularly in food and winemaking applications.

The safety that actually matters

• Ensure tanks and fittings are food-grade if used in food or beverage applications.
• Avoid using incompatible metals like copper and brass to prevent contamination.
• Use appropriate gaskets and fittings to maintain system integrity.
