It is a mild preservative that does not affect the taste or texture of the food significantly.
Unlike synthetic chemicals, sodium propionate is considered a natural preservative (derived from propionic acid, which occurs naturally in certain fermented foods like Swiss cheese).
It is effective over a wide pH range, making it useful in different food matrices.
Sodium propionate is generally recognized as safe (GRAS) by regulatory agencies such as the U.S. Food and Drug Administration (FDA) when used following established guidelines.
Chemical Formula: NaC3H5O2
Molecular Weight: 96.06 g/mol
Appearance: White, crystalline powder
Odor: Slightly pungent or no significant odor
Solubility: Soluble in water (around 70 g/100 mL at 20°C), moderately soluble in alcohol
Melting Point: 300°C (decomposes)
Boiling Point: Decomposes before boiling
Density: 1.48 g/cm³ (at 25°C)
pH (aqueous solution): Approximately 8-9 (in 1% aqueous solution)
Acidity/Basicity: Sodium propionate is slightly basic due to the presence of the sodium ion and the propionate ion (C3H5O2-).
Reactivity: It is stable under normal conditions and does not readily undergo chemical reactions unless exposed to strong acids or bases.
Functionality: Acts as a preservative and a fungicide, inhibiting the growth of mold and some bacteria in food products.
Reaction with acids: When combined with acids, sodium propionate forms propionic acid (CH3CH2COOH), which is a weak acid and may exhibit antimicrobial properties.
Food Industry: Used as a preservative, especially in baked goods, to prevent mold growth.
{Sodium propionate is typically used in very small amounts (usually between 0.1% and 0.3% by weight) in food products.}
Bread and Bakery Products: It is widely used in breads, cakes, and other baked goods to prevent mold growth, thereby extending their freshness. In these products, it help maintain quality by preventing spoilage during storage.
Cheese: Sodium propionate is sometimes added to cheese to control the growth of unwanted molds, especially in soft cheeses.
Processed Foods: It is also found in processed foods like muffins, cakes, and pie crusts to prevent mold contamination, especially in high-humidity environments.
Agriculture: Can be used as a feed preservative to extend shelf life.
Other Applications: Sometimes used in pharmaceuticals and cosmetics.
