This research studied the influence of storage conditions on the mechanical and electrical parameters of okra (Abelmoschus esculentus) pods. In this study, the okra pods were stored in two conditions - ambient condition (32±3˚C and 87±6% RH) and refrigerated condition (10oC and 65% RH), and strength parameters (failure force, failure energy, rupture force and rupture energy, and electrical properties (electrical conductivity and resistivity) were evaluated in three day interval for nine consecutive days (0, 3, 6, and 9 d). All the tests were conducted in accordance with American Society for Testing and Materials (ASTM) International procedures. Results from the research indicated that storage duration had a significant (p≤0.05) effect on all the parameters investigated. The rupture energy and electrical resistivity of the ambient batch inclined from 0.17 to 1.09 Nm and 2.653 to 3.356 Ωm, respectively; whereas, in the refrigerated batch, the rupture energy and electrical resistivity increased from 0.17 to 0.34 Nm and 2.653 to 2.841 Ωm, respectively. Notably, the electrical conductivity declined from 0.377 to 0.298 S/m and from 0.377 to 0.352 S/m, for the ambient and refrigerated conditions, respectively. Remarkably, the information gathered from this study will be helpful in automated okra pod integrity monitoring and the design and production of smart okra pod packaging structures.
