Why Screen for Sudan Dyes?

Sudan dyes are industrial dyes that are not permitted for use in foods.

They have historically been associated with adulteration incidents involving chili powder, paprika products, spice blends, seasonings, sauces and other processed food products.

Manufacturers, exporters, laboratories and inspection authorities routinely screen for Sudan dyes to support:

• Illegal dye risk control
• Supplier verification
• Incoming material inspection
• Export risk control
• Market surveillance programs
• Regulatory compliance monitoring
• Brand reputation protection
• Food safety risk management

The discovery of Sudan dye contamination after shipment, customer inspection or market release may result in shipment rejection, product recalls, regulatory action, buyer claims and significant reputational damage.

Front-end rapid screening helps identify suspicious batches earlier and supports faster risk-control decisions before products enter production or international trade channels.
