DANTAS, Alan Christie da Silva et al. Mechanical characterization of mango fruit using compression tests. Rev. de Ciências Agrárias [online]. 2017, vol.40, n.2, pp.100-110. ISSN 0871-018X.  https://doi.org/10.19084/RCA16095.

Brazil is one of the largest producers of mangoes, and the São Francisco Valley accounts for about 87 % of Brazilian exports of this product to the European market. This study aimed to characterize the mechanical behavior of the fruits according to the maturation stages, in order to prevent physical damage caused by improper handling of the fruit during harvest, storage, processing and transportation. The compression tests were performed on the mango cultivars (Mangifera indica L.) Keitt and Tommy Atkins at different maturation stages in order to characterize the internal elastic modulus and determine the maximum stress until rupture of the sleeve. The fruits showed a decrease in mechanical properties correlated with the increase of maturation stage, for both cutivars. The Tommy Atkins variety showed better mechanical properties probably related to a higher concentration of fibers in the pulp which yields better mechanical stabilization.

Palabras clave : elasticity modulus; mango; maturation; mechanical behavior.
