Sorbates are chemical preservatives (anti-microbial agents) capable of retarding or preventing growth of micro-organisms, such as yeast, bacteria, moulds or fungi, used primarily in food and beverages. Their principal mechanisms are to reduce water availability and increase acidity. Sometimes these additives also preserve other important food characteristics such as flavour, colour, texture and nutritional value. In addition to their use as a preservative in food and beverages, sorbates also perform well in the stabilisation of other types of products such as pharmaceutical products, cosmetics, pet food and animal feed.
