CIRO VELASQUEZ, HÉCTOR JOSÉ  e  OSORIO SARAZ, JAIRO ALEXANDER. EXPERIMENTAL ADVANCES OF THE POST HARVESTING HANDLING ENGINEERING OF COLOMBIANS FRUITS: RESISTANCE MECHANICAL OF UCHUVA FRUITS (Physalis peruviana l). Dyna rev.fac.nac.minas [online]. 2008, vol.75, n.154, pp.39-46. ISSN 0012-7353.

The rupture and flesh firmness forces to Uchuva fruits were determined using the destructive technique under unidirectional compression at constant deformation rate. The statistical results indicated that the flesh firmness and the mechanical resistance to the fracture in two loading directions (longitudinal and transversal) diminishes with the post-harvesting time where the mature fruit is more susceptible to mechanical damage with relation to pinton and green fruit.

Palavras-chave : Uchuva; flesh firmness; rheology; postharvesting.
