Propanoic acid inhibits the growth of mold and some bacteria at the levels between 0.1 and 1% by weight. Primarily used as a preservative in baked goods, which use the sodium and calcium salts. As a food additive, it is approved for use in the EU, USA and Australia and New Zealand. It is listed by its INS number (280) or E number E280. 收起 | |

It is a colourless solid that is slightly soluble in water and sublimes readily. Sorbic acid and its salts, such as sodium sorbate, potassium sorbate, and calcium sorbate, are antimicrobial agents often used as preservatives in food and drinks to prevent the growth of mold, yeast, and fungi. In general the salts are preferred over the acid form because they are more soluble in water, but it is the acid form that is active. Adding sorbate salts to food will, however, raise the pH of the food slightly so the pH may need to be adjusted to assure safety. It is found in many foods, such as cheeses and breads. 收起 |
