Origin:

Sodium salt of sorbic acid (E200), which naturally occurs in the fruit of the European Mountain-ash (Sorbus aucuparia ), after which the acid is named. It is commercially produced by several different chemical pathways.

Characteristics and Application :

Sodium sorbate is the sodium salt of sorbic acid.
Sorbic acid is a preservative, mainly against fungi and yeasts. It is not effective against bacteria. Optimal activity is at pH values below 6.5 (acid and slightly acid foods). Sodium sorbate is often used, as it is better soluble; its activity is similar to that of sorbic acid.
