uses of propionic acid:
Propionic acid CAS 79-09-4 is primarily used as a preservative due to its highly effective antimicrobial properties.
1. Food Preservation (Primary Use): Food-grade propionic acid (INS 280) is used as a preservative in selected food applications, particularly where control of mold growth is required. Applications may include bakery, grain-based and certain dairy products, subject to applicable local food regulations. Common food applications include bread, cakes, cheese, yogurt, and other grain and dairy products to inhibit mold growth.
2. Feed Preservation: Propionic acid is also used in animal-feed preservation applications where control of mold and microbial deterioration is required. It may be used for high-moisture grain and feed preservation, with application rates depending on grain moisture, feed composition, storage conditions and applicable regulations. For commercial use, customers should determine the final dosage according to local regulations and their formulation or preservation process.
3. Herbicide and Pesticide Intermediates: Propionic acid is an important chemical precursor for synthesizing various herbicides and pharmaceutical products.
4. Polymer Production: Used in manufacturing cellulose-based plastics and vinyl propionate, materials widely applied in paints, coatings, and plastic products.
5. Solvent and Chemical Intermediate: Serves as a resin solvent and chemical intermediate.
