EFFECT OF STORAGE TEMPERATURE ON QUALITY OF ARTICHOKES (Cynara scolymus L.)

The artichoke (Cynara scolymus L.) is grown mainly in Mediterranean countries and its immature flowers are commonly included in the Mediterranean diet. However, its consumption is very low in many countries and it is necessary to improve the postharvest handling in order to reach new markets. Highest quality heads show no violet discoloration on the inner bracts, a short pappus and outer bracts tightly closed and free of blemishes (Miccolis et al., 1988; Mencarelli et al., 1993). Bract opening, external and internal blackening and wilting are the main factors affecting quality during distribution (Escriche et al., 1982). The aim of this work was to evaluate the effect of storage temperature on the quality attribute changes of artichoke heads. Respiration activity and ethylene emission were also studied.
