Xanthan Gum Storage — Pseudoplastic Hydrocolloid Tank Selection

Storing Xanthan Gum? Start Here

Xanthan gum is a versatile thickener used in food, cosmetics, and oil drilling. It comes as a fine powder that turns into a gel-like solution when mixed with water. This substance is generally safe and non-corrosive, but it does require specific conditions for optimal storage. If you're dealing with xanthan gum, you'll want to ensure your storage setup is right to maintain its quality and effectiveness.

Can you store it in a poly tank?

Yes, you can store xanthan gum in a polyethylene (poly) tank. HDPE or XLPE tanks are standard for food, cosmetic, and pharmaceutical applications. These materials are non-reactive with xanthan gum, making them a safe choice for storage.

Watch out for microbial growth

One key issue with storing xanthan gum solutions is their vulnerability to microbial growth, especially in warm conditions. The gum itself doesn't prevent bacteria or fungi from growing, so it's important to keep storage conditions cool and consider preservatives if storing solutions for extended periods.

The safety that actually matters

• Ensure tanks are clean and dry before use to prevent contamination.
• Use food-grade gaskets like EPDM for food and pharma applications.
• Maintain a cool storage environment to minimize microbial growth.

Common questions

Can xanthan gum be stored in stainless steel tanks?

Yes, 316L stainless steel tanks are excellent for pharma and food-grade applications.

What kind of gaskets should I use?

EPDM gaskets are standard for food-grade applications, while Viton offers premium sealing.

How long can I store xanthan gum solutions?

It's best to use them within a few days, especially if stored in warm conditions without preservatives.
