CIRO VELASQUEZ, HÉCTOR JOSÉ; MONROY LAITON, FABIAN ARMANDO  and  CORTES MARIN, ELKIN ALONSO. BASIC STUDY OF THE RHEOLOGICAL RESPONSE UNDER UNIDIRECTIONAL COMPRESSION OF PLANTAIN PULP (Musa AAB Simmonds). Dyna rev.fac.nac.minas [online]. 2008, vol.75, n.155, pp.155-161. ISSN 0012-7353.

Samples of plantain pulp (Musa AAB Simmonds) were subjected to tests of unidirectional compression using an analyzer of texture TA-XT2i. The true flow curves (stress-strain) and rheological properties such as stress, strain and toughness to failure point were evaluated. The material was subjected under two loading direction (longitudinal and transversal) and three positions throughout the longitudinal axis of the product: initial, middle and final. The statistical analyses showed that the product is highly anisotropic, where the direction of load and the position within the material are significant effects in the rheological response of the material.

Keywords : Plantain; rheology; mechanical properties.
