- Abstract
The efficacy of sodium dichloroisocyanurate (Dichloro) and peracetic acid against Penicillium expansum, Byssochlamys fulva and Alicyclobacillus acidoterrestris was evaluated on apples surface and aqueous solution. P. expansum spores were efficiently eliminated in both conditions using dichloro and more than 6 decimal reductions (DR) were observed at 25ppm/6 min in aqueous solution. However, using peracetic acid against P. expansum spores was ineffective. In apple surface, the other microorganisms were reduced in < 1 logarithmic cycle, using both sanitizers. In aqueous solution dichloro was more effective than peracetic acid. B. fulva was the most resistant microorganism followed by A. acidoterrestris and finally by P. expansum. It follows that sodium dichloroisocyanurate was the most efficient sanitizer and its use is recommended at 25ppm in water used for cooling apples designated for storage, and in the wash water, in order to destroy P. expansum spores and to reduce the risk of patulin production in juice. None sanitizer used were efficient against A. acidoterrestris and B. fulva spores.
