Technical Abstract: A comparison of sanitizers for whole and fresh cut (cv. Keitt) mango was made. Mangos were obtained from a farm in Homestead, Florida, and stored at 5C until processed. The fruit were pre-washed with warm water; air dried and dipped in prepared solutions of either NaOCl (200 ppm) or a commercial formula of peroxyacetic acid/ hydrogen dioxide (1%). After sanitizing, the fruit were air dried, placed in clean containers and ripened at 27C. The fruit were sanitized again in preparation for cutting, and the cut pieces were treated in a 20+ second dip with either a commercial solution of acidified NaOCl (200 ppm) or peroxyacetic acid/hydrogen dioxide (0.5%). Resulting cut slices were placed in polystyrene clamshell food containers and stored at 5C. Samples in the clamshells were tested for changes in microbial stability and for quality parameters (color, firmness) every 7 days. These studies showed that cut pieces from whole fruit treated with the peroxyacetic acid formulation, then sanitized with dilute peroxyacetic acid or acidified NaOCl after cutting, had less contamination than sanitized pieces cut from whole fruit treated with NaOCl.
