Popis:	Six textural characteristics, deformation, epicarp strength, locular resistance, firmness, compliance and toughness, were calculated from force/ deformation curves obtained by punch testing tomato friuits (Lycopersicon esculentum Mill cv Vendor) in which sunscald had been induced by radiation stress. Sunscalded portions of unstored fiuits had higher compliance and lower firmness values than the uninjured portions. For the stored fruits, the magnitude of the ripening-induced decrease in epicarp strength, locular resistance and firmness associated with storage was significantly reduced by ‘incipient’ injury and eliminated by ‘advanced’ injury. Preferential ripening of the uninjured portions increased deformation and toughness beyond expected values. Various sunscald symptoms such as inhibition of fruit softening, the production of tough tissues, the localisation of sunscalded tissues and the differential ripening of uninjured parts relative to the sunscalded portions can be detected by determining force-deformation characteristics of the sunscalded tomato fruits.
