Sodium Diacetate Feed Grade Supplier South Africa

What is Sodium Diacetate?

Sodium diacetate (SDA) is a molecular complex of sodium acetate and acetic acid (CH₃COONa·CH₃COOH), available as a free-flowing white crystalline granule that is easy to handle, dust-free, and free of the corrosion and odour problems associated with liquid acetic acid. Upon dissolution, it releases acetic acid and provides antimicrobial and antifungal activity through the undissociated acetic acid fraction in acidic environments. It is one of the most commonly used dry-form acetic acid preservatives in the food and feed industries.

Role in Animal Nutrition

Sodium diacetate is a practical preservative for compound feed and grain storage, providing both antifungal protection and flavouring in a single ingredient. In compound feed, it inhibits mould growth and helps control Salmonella contamination in finished feed. Its acetic flavour profile enhances palatability in livestock and pet feeds. It is particularly valued as a dry alternative to liquid acetic acid, allowing easy metering and blending into dry compound feeds without specialised equipment. In pet food dry kibble, SDA helps extend shelf life and contributes to a mildly savoury profile.
