Sorbic acid, or its various sorbate salts, is the most widely used chemical preservative in the industry as an antifungal because other similar preservatives were limited or banned in the past.
Despite its widespread presence, it is mostly effective at pHs below 4.8, so for many foods it is not sufficient protection and/or is combined with other antifungals. This further compromises a clean label. In addition, the accumulation of this acid and others can compromise the organoleptic of the food.
It is really difficult to find a compound with effective antifungal capabilities, especially in nature, but within Amerex natural preservatives we have specialist products for this application that can replace even sorbate by its direct action.
