As mango is a climacteric fruit, the maturity stage at harvest is paramount in determining the final product quality after postharvest ripening. The method of manually “tapping” mangoes, a traditional practice of farmers, utilizes the acoustical properties the fruits to decide harvest time. Mango fruit acoustics change over time as the mango seed develops and the surrounding cavity that initially exists within the endocarp fills. Usually, this method is used in parallel with visual evaluation of the mesocarp color around the endocarp to ensure that the decision of harvest time is based on two different criteria. Supporting the development of an objective, non-invasive acoustic maturity analysis, a study on the dynamics of the cavity closure mentioned above was conducted monitoring maturation and post-harvest ripening of mango fruits (cv. Chok Anan) grown in a research orchard at Mae Jo University, Thailand. Fruits analyzed at 2-3 day intervals during maturation and ripening were cross sectioned along the sagittal plane. The areas of the seed and endocarp were measured by use of a millimeter raster. As a result, the closure of the cavity was documented and correlated with other parameters of mango development that are conventionally used in destructive characterization of harvest maturity and ripeness. Knowledge about the ripening behavior, including the dynamics of the cavity closure, may promote the definition of thresholds for picking maturity in development and calibration of acoustic maturity sensors based on resonance.
