Understanding the Role of EDTA-2Na in Food Preservation

Ethylenediaminetetraacetic acid disodium salt (EDTA-2Na, CAS 6381-92-6) is one of the most widely used chelating agents in the food industry. This article explores its mechanisms, applications, and safety profile.

How EDTA-2Na Works

EDTA-2Na functions by binding to metal ions that can catalyze oxidation reactions in food products. By sequestering these ions, it effectively slows down degradation processes and extends shelf life.

Key Applications

• Canned vegetables and fruits - prevents color and flavor deterioration
• Salad dressings and sauces - maintains emulsion stability
• Soft drinks - protects against metal-catalyzed oxidation
• Processed seafood - reduces off-flavor development

Regulatory Compliance

EDTA-2Na is approved by FDA (21 CFR 182.60), EFSA (E385), and listed in GB2760. Maximum usage levels vary by food category, typically ranging from 25-750 mg/kg.

Quality Standards

Our EDTA-2Na meets FCC, USP, and EP specifications with purity ≥99.0%, ensuring consistent performance across applications.
