Résumé

Impedance is regarded as a potential non-destructive measure of tissue damage following heat treatment. Reflectance, colour, soluble solids content, were measured along with impedance, before and after hot-water treatment and during storage. Several correlations were investigated. Impedance of hot water treated fruits was poorly correlated with soluble solid content and chroma but well correlated with reflectance of fruit pulp at 22 °C. Changes in impedance of mangoes are discussed in relation to physiological and biochemical changes that occur during heat treatment and storage.
