Abstract : During 1997 and 1998, sapburn caused losses of up to 9.9% of the annual Mexican mango production destined for exportation. Our objective was to investigate whether some chemical compounds could reduce the incidence of sapburn in harvested mangoes. Efficiency of solutions of lauryl sulfate sodium (LS), Tween 80, sodium carboxymethyl cellulose (CMC), mixtures of LS with CMC and Tween 80 with CMC were evaluated in mango fruits (cultivars Haden and Tommy Atkins). Treatment efficacy was determined by measuring sapburn areas of mango skin, and calculating the damage index by statistical analyses. Quality parameters and organoleptic characteristics were also determined. Treatments with CMC, lauryl-CMC and Tween 80-CMC proved to be most effective at reducing sapburn. Chemical and organoleptic quality of fruits were not altered due to the chemical products used.
