Sodium benzoate and Potassium sorbate is equally effective against bacteria, yeasts and mould fungi. It is a typically biostatic product with the biocidal properties necessary for practical use.
For Sodium benzoate & Potassium sorbate to perform effectively in destroying organisms in products already contaminated, a minimum contact time of 48 hours is necessary.
Since the effect of Sodium benzoate & Potassium sorbate takes place through chemical reactions with the microorganisms, when it is used in heavily contaminated products loss of active ingredient must be taken into account.
Good production hygiene, as well as the use of raw materials with low microorganism levels as a result of correct raw material control, are of course vital prerequisites for the production of microbiologically faultless finished products.
