Abstract

Preservation of animal feed, grain and food (calcium and sodium propionates) accounted for just over 78% of world propionic acid consumption in 2009, followed by various herbicides and diethyl ketone. Other smaller-volume applications include cellulose acetate propionate, pharmaceuticals, solvent esters, flavors and fragrances, plasticizers, dyes, and textile, leather and rubber auxiliaries. Demand for propionic acid is largely dependent on the production of animal feed and grain, followed by packaged food and bakery products.

The following pie chart shows world consumption of propionic acid:

The U.S. Food and Drug Administration (FDA) has approved propionic acid as a direct food substance affirmed as GRAS (Generally Recognized As Safe). It can be used in food for human consumption at levels not to exceed current good manufacturing practice. In direct food applications, propionic acid is approved as:

• An antimicrobial agent
• A flavoring agent

World growth prospects for propionic acid and its salts in animal feed/grain preservation and food are significant, for the following reasons.

There is significant demand growth in the use of propionic acid in animal feeds and grains as a preservative. This market is expected to grow quickly in nearly all regions as demand for meat is increasing, particularly in developing countries. In addition, living standards are improving, particularly in Asia, and convenience is highly desired (increased popularity of processed foods). There is increased need for food safety (preservation); longer shelf lives are anticipated as more food and ready-to-drink beverages are consumed days or weeks after production.
