Sorbate
Also known as Potassium sorbate, Sorbic acid, E202
Potassium sorbate and sorbic acid, mild antifungal preservatives used chiefly on casing surfaces to hold back unwanted moulds and yeasts.
Sorbate, usually potassium sorbate or the parent sorbic acid, is a mild preservative that works mainly against moulds and yeasts. Like natamycin it is used as a surface treatment on casings, by dipping or spraying, to keep unwanted fungi off products where surface mould is a defect.
It is more effective at the lower pH a fermented sausage reaches, and it is sometimes paired with other hurdles. As a fungal-targeted treatment it has no place on a mould-ripened product, where it would work against the noble flora, and its permitted use and level are set by regulation.
