Uses and synthesis of Sodium dehydroacetate powder

Sodium dehydroacetate powder is white or light yellow, odorless, tasteless, easily soluble in water, difficult to dissolve in ethanol and other organic matter. Melting point is 190°C, light resistance, good heat resistance. The solution is heated at 120°C for 2 hours and remains stable. The aqueous solution appears neutral or slightly alkaline. Sodium dehydroacetate is a kind of food preservative with broad spectrum and strong bacteriostatic ability, which has a particularly strong inhibition ability to mold and yeast. Under the same amount of addition, the antibacterial effect is several times or even dozens of times higher than the widely used sodium benzoate and potassium sorbate. What is particularly valuable is that the inhibition of acid-producing bacteria, especially lactic acid bacteria, is very small.

Sodium dehydroacetate is a new generation of food preservatives after sodium benzoate, parabens, and potassium sorbate. It has a good inhibitory effect on mold, yeast, and bacteria. It is widely used in the processing industry of beverages, food, and feed, which can extend the storage period and avoid mold loss.

Its mechanism of action is to effectively penetrate into the cell body and inhibit the respiration of microorganisms, thereby achieving the effects of anti-corrosion, anti-mildew, fresh-keeping, and moisturizing.

Sodium dehydroacetic acid has a broad-spectrum antibacterial ability, especially against mold and yeast. Sodium dehydroacetic acid has a strong effect on yeast and mold that cause food corruption. The effective inhibitory concentration is 0.05%-0.1%, and the general dosage is 0.03%-0.05%.

It is mainly used in fermented bean curd, pickles, jams (maximum dosage 0.3 g/kg); soups, cakes and cheese, cream, margarine, etc. (maximum dosage 0.5 g/kg); the maximum dosage in salted vegetables is 0.3 g/kg

Sodium dehydroacetate vs sodium benzoate

Sodium dehydroacetate is preferred:

Neutral/alkaline foods (such as bread, soy products).

Foods that require high temperature processing (such as baking, meat products).

Cosmetic preservation (more stable, less irritating).

Sodium benzoate is preferred:

Acidic foods (such as juice, carbonated drinks).

Low-cost preservation needs (such as soy sauce, vinegar).

Applications/Functions of Sodium dehydroacetate powder

• Sodium dehydroacetate powder is used as food additive, preservative and fungicide
• Sodium dehydroacetate powder is a kind of antibacterial agent with high safety, wide antibacterial range and strong antibacterial ability. It is less affected by the pH in food, and can maintain high antibacterial efficacy under acidic or slightly alkaline conditions. Sodium dehydroacetate in pharmaceutical applications was superior to sodium benzoate, potassium sorbate, calcium propionate and was an ideal preservative for food.

Physicochemical Property of Sodium dehydroacetate powder

Sodium dehydroacetate price per kg white or nearly white crystalline powder. Odorless, slightly special taste. Melting point 109 ~ 110℃. Soluble in water, propylene glycol and glycerol. It is slightly soluble in ethanol (1%) and acetone (0.2%). Good light and heat resistance. The aqueous solution remained stable after 2h heating at 120℃. The aqueous solution is neutral or slightly alkaline.

Production methodprocess of Sodium dehydroacetate powder

Sodium dehydroacetate powder was prepared by neutralizing dehydroacetate with sodium hydroxide.
