What is Sodium Diacetate?

 

Definition

 

Sodium diacetate is a chemical compound with the formula NaC4H4O4. It is a salt of acetic acid and sodium hydroxide, soluble in water. Sodium acetate is used to make other chemicals, as well as substances like soap and glass, and has been found in meteorites.

Sodium diacetate was discovered by French chemist Henri Victor Regnault in 1847. It was first prepared by heating acetic acid with sodium hydroxide at 100 °C under pressure. The major industrial route today involves heating sodium acetate with acetic anhydride at 200–300 °C:

The resulting mixture is distilled under a vacuum to give the product a white solid in 80% yield. It can also be produced by passing carbon dioxide through an aqueous solution of caustic soda containing dissolved acetate salts, followed by evaporation of the liquid phase to give a crystalline mass which is filtered off and dried.

What is sodium diacetate used for in food?

 

Sodium diacetate is a preservative that prevents the growth of molds and yeasts in food. It’s often used with other preservatives, such as sodium erythorbate and sodium nitrite, to inhibit bacterial growth.

Sodium diacetate can be found in many types of food products, including:

Baked goods

Sauces

Canned meat and vegetables

What’s sodium diacetate used for?

 

Sodium diacetate is an organic compound that is a white solid. It is also known as sodium bisulfite, sodium acid pyrophosphate, and disodium hydrogen pyrophosphate.

Sodium diacetate is used to preserve foods and as an antiseptic agent. It is also used in the production of drugs and other chemicals, in the textile industry, for bleaching hair, and as a deodorant.

Sodium diacetate is used to preserve foods by inhibiting the growth of bacteria and mold. It can be used in combination with other preservatives such as sorbates or benzoates to inhibit yeast growth. It may be used alone or in combination with other preservatives such as sorbates or benzoates to inhibit yeast growth.

Sodium diacetate can be used as an antiseptic agent for cleaning wounds and skin abrasions, but it may cause swelling if it comes into contact with broken skin so it should not be applied directly to unbroken skin.

Sodium diacetate is used as an acidity regulator and flavor enhancer in cheese products, canned fruits, vegetable products, pickles, and sauces; as a preservative in dried fruit and nut products; and as an ingredient in pet foods.

What is sodium diacetate made?

 

Sodium diacetate is a chemical compound with the formula NaC2H3O2. It is the sodium salt of acetic acid and is also known as pyrosulfuric acid (PDC).

The pure substance is colorless. It forms crystals that are highly soluble in water, alcohols, ethers, esters, and chloroform. Sodium diacetate is produced from acetic acid by the following reaction:

CH3COOH + NaOH → CH3COONa + H2O

How is sodium diacetate made?

 

Authorities, such as the FDA and EFSA, generally mention two manufacturing processes.

As per FDA 21CFR184.1754, its technical grade is produced by reacting sodium carbonate with acetic acid or by reacting anhydrous sodium acetate with acetic acid.

As per the information provided by EFSA, sodium hydroxide reacts with glacial acetic acid to produce sodium acetate, leaving sufficient free acid after the reaction.

What is the application of sodium diacetate?


As a result of its antimicrobial properties, vinegar taste, and PH regulation, it can be used in food, feed, cosmetics, and pharmaceutical products.

Food


Generally, it is used in bakery products, meat products, and savory products. In addition, it is easy to use and transport, as liquid acetic acid must be transported in a liquid form.

Bread


Preservatives such as this are used in bread dough to extend shelf life. Additionally, it exhibits synergistic antimicrobial properties with calcium propionate.

Meat


A low level of sodium diacetate (e.g., less than 0.2%) can lower the pH of meat products, inhibiting the growth of molds and bacteria, such as Listeria monocytogenes.

The reason for this is not only its pH-lowering effects but also the inhibition of listerial growth by the acetate ion.

In combination with sodium diacetate, sodium lactate or potassium lactate retards microbial growth more effectively.

Savory products


Due to its high concentration of acetic acid (39-41%), In addition to being a dry vinegar, it serves as a flavoring agent. The ingredient is commonly used in savory products such as cookies, chips, condiments, sauces, soups, potato crisps, and salads.

Acidity adjustment


In food, it acts as a buffering agent. Liquid or dry, it can be applied easily.

Feed additive


Preservatives such as sodium diacetate can be used in poultry, pig, and pet feed.

Cosmetics


According to the “European Commission database for information on cosmetic substances and ingredients”, it can act as a buffering and masking agent.

Pharmaceutical


In dialysis solutions, sodium diacetate controls the pH level. Clinics also benefit from storing dry mixes rather than liquid products, since only a liquid product needs to be dissolved.

Is sodium diacetate bad for you?


Sodium diacetate is used in medical and cosmetic treatments as a desiccant. This means that it’s used to dry out wounds, cuts, and burns. It’s also found in many cosmetics because it has a low level of toxicity and it won’t irritate the skin.

It’s important to note that sodium diacetate isn’t typically used as an active ingredient in these products, but rather as an inactive ingredient meant to help preserve other ingredients. The problem with this is that there are no long-term studies on the effects of sodium diacetate on humans or animals. As such, it’s difficult to say whether or not it could cause negative health effects over time or if there are any dangers associated with using products containing this ingredient.

There are some reports that suggest that sodium diacetate can be harmful when ingested or inhaled in large amounts over time, but these reports aren’t backed up by scientific evidence and haven’t been proven by researchers who specialize in these areas of study.

What are the Possible side effects of sodium diacetate?
