Abstract

Leaves of three different sweet basil (Ocimum basilicum L.) cultivars (Italico a foglia larga, Cammeo, andItaliano classico) packed in macro-perforated polyethylene bags were stored at chilling (4 C) or nonchillingtemperature (12 C) for 9 days. During storage, visual quality, physiological (respiration rate,ethylene production, ammonium content) and chemical (antioxidant activity, total polyphenols andpolyphenol profile) parameters were measured. Detached leaves stored at chilling temperature showedvisual symptoms related to chilling injury, while ethylene production and ammonium content resultedassociated to cultivar sensibility to damage at low temperature. Storage at 4 C caused a depletion inpolyphenols content and antioxidant capability, which was preserved at 12 C. Regarding the polyphenolsprofile, stressful storage conditions did not enhance the phenolic metabolism. However, leavesstored at 12 C did not loss a significant amount of metabolites respect to fresh leaves, suggesting the possibilityto extend the storability after the expiration date, for a possible recovery of bioactive compounds.
