ANTIOXIDANTS IN APPERTISED PRODUCTS: SEARCH FOR SUBSTITUTES TO SODIUM METABISULFITS

The efficacy of SO2 and its derivatives (mainly implemented as sodium metabisulfits) as an antioxidant additive has been demonstrated for a long time for appertized products sensitive to browning. This protection is particularly useful for appertized potato products, packed in flexible plastic packages, for which the residual oxygen permeability is the limiting factor of the shelf life.
