Description

Propionic acid (CAS No.: 79-09-4) is a naturally occurring three-carbon carboxylic acid and an intermediate in human metabolism. Its core value lies in its strong inhibitory effect against molds, bacteria (especially Bacillus subtilis, which causes rope spoilage in bread), and certain yeasts, while being relatively safe for humans and animals. Consequently, approximately half of the global propionic acid production is used as a preservative and anti-mold agent for animal feed (silage, compound feed) and grains (food grains, feed raw materials), effectively preventing spoilage and extending storage life. In the food industry, propionic acid and its sodium and calcium salts are safe food additives (e.g., E280) used for mold prevention in baked goods such as bread and pastries. In the chemical sector, it is an important starting material for producing propionate esters (excellent solvents and fragrances), propionates (used as preservatives and rubber additives), herbicides (e.g., propyzamide), and pharmaceuticals (e.g., as an intermediate for the non-steroidal anti-inflammatory drug ibuprofen). Our product, manufactured in Shandong, China, is produced via advanced processes such as propionaldehyde oxidation, achieving a high purity of ≥99.5% with light color and low moisture and impurity content. Its quality meets both food-grade and industrial-grade standards, catering to diverse needs in feed preservation, food additives, and fine chemical synthesis.
