Se hizo la caracterización reológica de la uchuva (Physalis peruviana L.) a través de la respuesta mecánica bajo ensayos de compresión unidireccional a pruebas de firmeza y fractura, para 3 grados de madurez (verde, pintón y maduro) y los días transcurridos después de la cosecha (1, 3, 5, 7, 9 días). Los resultados indicaron que la fuerza de firmeza y la resistencia mecánica a la fractura en dos sentidos de carga longitudinal y transversal disminuyen con el tiempo de poscosecha de la fruta, indicando que el fruto maduro es más susceptible al daño mecánico con respecto al verde y pintón.
