Whey Concentrate WPC-80 Storage — Dairy-Ingredient Tank Selection

Storing Whey Protein Concentrate (WPC-80)? Start Here

If you're handling Whey Protein Concentrate (WPC-80), you're dealing with a versatile dairy ingredient used in everything from cheese to sports nutrition. It comes in three main forms: liquid concentrate, powder, and rehydrated solution. Each form has specific storage needs, but the key is maintaining food safety and quality. Whether you're a cheese producer or a food formulator, understanding the right storage solutions is crucial for keeping your operations running smoothly and your products top-notch.

Can you store it in a poly tank?

Yes, you can store WPC-80 in FDA-compliant HDPE or XLPE poly tanks. These materials are suitable for dairy storage, particularly for less-stringent applications like hot-water make-down of rehydrated powder or day tanks at food-formulation plants. However, for higher-purity needs, especially in infant formula or sports nutrition, consider using PVDF or PTFE.

Key Issue: Biofilm Formation

WPC-80's high protein and fat content can lead to biofilm buildup, which requires rigorous cleaning. This means your tank material must withstand aggressive cleaning agents. Regular maintenance and cleaning protocols are essential to prevent contamination and ensure product quality.

The safety that actually matters

• Ensure tanks and fittings are made from FDA-compliant materials.
• Use 3-A approved EPDM or silicone gaskets for sanitary seals.
• Avoid materials like copper and brass that can cause off-flavors.

Common questions

Can I use standard poly tanks for all WPC-80 storage?

Yes, for general applications, but consider stainless steel for more stringent needs.

What gasket materials are recommended?

EPDM and silicone are preferred for their sanitary properties.

How do I prevent biofilm in my storage tanks?

Implement a regular cleaning schedule with appropriate cleaning agents.
