Nondestructive detection of low temperature induced stress on postharvest quality of kápia type sweet pepper

Abstract Application of cold storage temperatures below optimum induces a high risk and threat chilling injury (CI) in the case sensitive commodities. Sweet pepper belongs to this group vegetables, so our main objective was investigate monitor effect non-optimal (2.5 5 °C) induced stress (chilling injury) on kápia type sweet ( Capsicum annuum L. ) during its postharvest by nondestructive quality measuring methods. Fresh, semi-matured (reddish-green colored) samples ‘Kapitány F 1 ’ cultivar were stored at 2.5, 10 °C for 7 d followed shelf-life. Nondestructive texture measurements carried out purpose built tabletop acoustic stiffness device. Surface color chlorophyll content related indices evaluated chroma meter, DA-meter® fluorescence imaging system. High resolution digital pictures captured analyzed possible CI defects means surface values (normalized RGB, hue saturation). According results, (DA-index®, coefficient, parameters; 0 , m v /F parameters) clearly represented temperature dependent changes low storage, subsequently ambient Samples under showed stressed symptoms delayed partly retarded ripening, even simulated shelf-life conditions, but without onset manifestation characteristic visible injury. This may raise doubts suggest future research areas regarding role stress, contributing factors consequences.
