Technical Specifications

What Is Feed-Grade Sodium Diacetate and How Does It Work?

Sodium diacetate is a chemical combination containing sodium acetate and acetic acid in a 1:1 ratio . It is frequently nicknamed “dry vinegar” in the feed business. Its crystalline lattice structure enables the gradual release of undissociated acetic acid upon contact with moisture in feed matrices.

This slow-release process makes it very effective. The undissociated acetic acid penetrates the microbial cell walls far more efficiently than the dissociated ions and affects membrane transport in moulds such as Aspergillus and Penicillium and bacteria such as Salmonella and E. coli.

In monogastric animals, particularly weaned piglets, high stomach pH decreases pepsin activity and increases the risk of post-weaning diarrhoea. Sodium diacetate decreases the buffering capacity of the meal, giving a better environment for healthy gut development.

Key Product Characteristics

Our feed-grade Feed-Grade Sodium Diacetate offers several technically meaningful advantages over conventional preservatives:

· Enhanced antibacterial activity: More effective than calcium propionate at comparable doses because to increased undissociated acid content.

· Nutrient contribution: Acetate ion joins the Krebs cycle as a metabolisable energy source, offering nutritional value as well as preservation.

· High Palatability: The mild acetic scent promotes voluntary feed consumption in cattle and poultry, unlike unpleasant liquid acidifiers.

· Processing stability: is decomposed only over 150°C which guarantees complete stability during pelleting and extrusion (often below 85°C).

- Non-corrosive handling: Less corrosive to feed mill equipment than liquid organic acids, leading to fewer maintenance problems.

· Shelf life extension: Inhibits mold, yeast, and bacterial growth, extending feed shelf life by 2–3 times compared to unprotected feed.

Core Application Scenarios

Sodium diacetate is added to chicken feed, cattle feed, aquatic feed and pet food formulations in three major ways:

Feed Preservation: For use in the preparation of feeds to prevent the formation of mould and bacteria in wet grains, silage and mixed feeds. It works especially well in high humidity situations when standard preservatives have difficulty functioning.

Moisture Retention and Texture Maintenance: Prevents hardening and crumbling during storage, maintaining texture of feed and minimising loss of nutrients owing to oxidation or microbial activity.

pH regulation: It is used as an acidifier in complete feed formulations and enhances the stomach acidity in monogastric animals, boosting the efficiency of protein digestion and reducing digestive issues in young animals.

It is also highly water soluble (1 g per 1 mL) which makes it convenient to employ in liquid feed systems and drinking water acidification programs.

FAQ

Q: Sodium diacetate is advised to be added to poultry and cattle feed at levels of 0.1 to 0.5 percent.

A: Generally inclusion rates are 0.1 to 0.3% of the total feed weight depending on the moisture content, storage conditions, and target animal species.For advice on a particular formulation please contact our technical team.

Q: Does the product remain stable during feed pelleting?

A: Yes. Normal pelleting temperatures are under 85°C whereas the product only breaks down beyond 150°C. This maintains full anti-bacterial and functional activity in thermal processing.

Q: How efficient is sodium diacetate as a feed preservative and how does it compare to calcium propionate?

A: Sodium diacetate is more effective as a fungicide at equal treatment rates because the undissociated acetic acid can more easily permeate microbial cell membranes. It also supplies metabolisable energy via the Krebs cycle while calcium propionate does not.

Q: Is it suitable for use in aquatic feeds and pet food formulations?

A: Yeah. Suitable for the manufacture of cattle, poultry, aquatic and pet feed. It is very soluble and has a moderate flavour character that may match a broad variety of formulation types.

Q：What regulatory and import paperwork is provided?

A: We can provide multi language MSDS, COA, Halal/ Kosher certifications and compliance documentation. We also help clients with chemical export papers and customs clearance support.

Q: What is the pricing of the feed grade sodium diacetate E262 ? MOQ ?

A: Prices vary according on order amount, packing type and trade terms (FOB, CIF or DAP). If you would like a price unique to your needs, please contact us directly.
