POSTHARVEST RIPENING IN WAX-COATED BOCADO MANGO

The effect of three different concentrations of two commercial wax coatings on some parameters of post-harvest ripening was evaluated. The rate of loss of fresh weight of mangoes was reduced with both waxes at higher concentrations Chlorophyll degradation of the exocarp (skin) and the increase in mesocarp (flesh) pH normally occurring during ripening was retarded at higher concentrations of both wax coatings. However Primafresh 31 was less effective than Primafresh C at similar treatment concentrations. The results showed that the delayed ripening effects of wax-coated fruits affected fresh weight loss, exocarp chlorophyll degradation and mesocarp pH change but did not affect mesocarp chlorophyll, sugar, and starch content.
