Occurring naturally in some fruits Sorbic acid can be commercially manufactured synthetically from the toxic, irritant, colourless gas ketene. (See also E201, E202 and E203)

As a preservative it effectively inhibits the growth of yeasts and moulds whilst allowing bacterial activity, e.g. in cheese, both non-processed and processed. Also may be used in sweet wine making but can sometimes produce 'off flavours'.

In addition to its use in these areas it can also be found in candied peel, cider, dessert sauces, fillings and toppings, fermented milks, frozen pizzas, fruit salads, gelatin capsules, soft drinks, soup concentrates, sweets, yoghurt, medicines and cosmetics.

A possible skin irritant.

Not approved for use in Australia.
