Comportamiento mecánico de frutos de papaya bajo compresión axial

Abstract: Los frutos de papaya (Carica papaya L.) son muy susceptibles a los daños mecánicos, lo que repercute en fuertes pérdidas en poscosecha. El objetivo del presente trabajo fue evaluar el comportamiento mecánico de frutos de papaya en poscosecha, para lo cual se realizaron dos experimentos en el Campo Experimental Las Huastecas, INIFAP durante los años 2011 y 2012. Las variables evaluadas fueron la fuerza y la deformación requeridas por los frutos para alcanzar el límite elástico, el punto de … Show more

“…Fruit structure could be analyzed as a multilevel continuity object (Cáez‐Ramirez, Téllez‐Medina, & Gutierrez‐López, 2015), therefore, each part of the fruit tissue contributes to the viscoelastic response. Papaya tissue mechanical behavior was explained by Maxwell elements as follows (Figure 6): E 0 represents the superficial tissue breakdown of the fruit (Vázquez García, Mata Vázquez, Ariza Flores, Santamaría Basulto, & Alia Tejacal, 2013); E 1 and τ 1 represent the deterioration of the primary cell wall and the middle lamella, and the second elements E 2 and τ 2 represent other structural features related to the polysaccharide network and molecular linkages rearrangement possibly associated with cell––cell adhesion (Cáez‐Ramírez, Alamilla‐Beltrán, & Gutiérrez‐López, 2018; Karaman et al., 2016; Yildiz et al., 2013). Peleg model was represented by “ a ” and “ b ” parameters, whose physical meanings were related to the decaying level and the rate at which this happens during the relaxation, respectively (Peleg, 1979).…”

“…In studies carried out on mechanical resistance to rupture in papaya variety Maradol Red, rupture point values of approximately 90 N were reached for the consumption ripeness stage and 250 N in other cultivars of the same variety. Physiological ripening (degrees of ripeness 0.1 and 2) can have maximum strength of rupture values of 2000 N and 2,500 N, as reported by Vázquez et al (2003Vázquez et al ( , 2013.…”
