Technical Specifications

​​​​​​​What Is Sodium Diacetate E262?

Sodium diacetate (E262) is a molecular combination of sodium acetate and acetic acid in the molar ratio of 1:1. In the industry it is commonly called “dry vinegar” because of its controlled release of acetic acid.

Its crystal lattice structure differs from a simple physical mixture, allowing for a steady, continuous release of undissociated acetic acid when exposed to moisture. It is this process that is successful in breaking the microbial cell membrane and reducing intracellular pH – therefore increasing product shelf life at low dose levels.

It is completely soluble, combines homogeneously with dry and wet formulations and does not induce unfavourable interactions with proteins, carbohydrates or fats in food matrices.

Key Product Characteristics

When finding a food grade preservative, two of the most crucial traits to look for are high purity and strict impurity control. This product passes both criteria, with a purity ≥98% and heavy metal content ≤0.001%, which meets international food safety regulations.

It has a wide range of antibacterial action against typical spoilage microorganisms including moulds, yeasts and bacteria such as Listeria and Salmonella. This makes it suited for situations where mould suppression and bacterial control are needed at the same time.

The dual capability of preservation and pH control allows you to solve two formulation difficulties with one ingredient. This streamlines your supply chain and cuts down on the amount of additives your product mix needs.

Application Scenarios

Bakery goods

This component is usually utilised at 0.1% to 0.4% in dough recipes. At this levels it will successfully block “rope” bacteria and mould, which are typical problems in baking situations of high moisture and high temperature.

An important benefit over calcium propionate is that the product has little inhibitory impact on yeast activity at acceptable dose levels. This implies your proofing times stay same but your shelf life is much enhanced.

Meat and Poultry Processing

It is an important bacteriostat against Listeria and Salmonella in processed foods as frankfurters, roast beef and deli slices. It is widely established that the lactate/diacetate mix, when used in conjunction with sodium lactate, acts synergistically to reduce water activity and intracellular pH.

This mixture keeps the freshness all through the cold chain without any harsh acidic flavour in the final product.

Dry Seasonings and Snack Foods

Sodium Diacetate is used as dry vinegar powder for seasoning in the seasoning business for savoury snack applications. It gives an instant " salt and vinegar " flavour punch and exploits its hygroscopic nature to assist the seasoning stick to chip surfaces.

That prevents the flavour from blowing off during packing and shipment – a real advantage for high-volume snack makers.

Further Applications

It is also employed as an acidity regulator and a mould inhibitor in condiments, pickled foods, aquatic goods and drinks. It is versatile for use across various product categories and is compatible with a broad variety of culinary ingredients.

FAQ

Q: What is the suggested use level in food applications?

A: Generally 0.1 to 0.4% of dough weight for baked products. The quantity used is dependent on the application, with meat products and sauces requiring different quantities depending on the intended pH and preservation goals.

Q: Is sodium diacetate E262 used to affect yeast in bread formulations?

A. It does not appreciably reduce yeast activity at the recommended dosing levels. This is a key practical advantage over calcium propionate since proofing behaviour is not impacted.

Q: Is this product Kosher and Halal?

A: Yes. The company is both Halal and Kosher certified to assist address these unique market demands for proper food grade products.

Q: What documentation do you supply for import and regulatory?

A: We offer COA, MSDS and compliance paperwork available in many languages. The team may also help with customs and import paperwork requirements.

Q: How pure is sodium diacetate CAS 126-96-5?

A: CAS 126-96-5 product is supplied at ≥98% purity and controlled heavy metals ≤0.001%. It's food-grade.

Q6: What's the MOQ and lead time ?

A: The lead time is 5-7 business days as typical. Stock Orders may take up to 24 hours to complete. Contact the Team to discuss MOQ and price based on your volume needs.
