Abstract : This study aimed to verify sanitizers influence (ozone and sodium hypochlorite) in polyamines content (putrescine, spermidine and spermine) during refrigerated storage and marketing simulation on organic and conventional mangoes. Mangoes Palmer organically and conventional cultivated, acquired from Borborema-SP (21°37?11?S, 49°04?25?W and 429 m) and Taquaritinga-SP (21°24?21?S, 48°30?18?W and 565 m), respectively, both from Brazil, were used. Fruits were subjected to following treatments: control samples (fruits grown in organic and conventional system, washed with public water supply); chlorine sanitized samples (fruits grown in organic and conventional system, submerged in chlorinated water, 100 mg L-1 sodium hypochlorite per 10 minutes); ozonated samples (fruits grown in organic and conventional system, submerged in ozonated water, 1 ppm, per 10 and 20 minutes). Bioactive amines qualiquantification was performed on harvest day and seven days of cold storage followed by four and eight days of storage at room temperature to simulate marketing. In general, during storage, the characteristics were not influenced by sanitizers, suggesting that chlorine can be replaced by ozone without compromising quality characteristics.
