Broccoli (Brassica rapa L.) of Lingua di cane ecotype were cultivated in presence and in absence of a sulphuric fertilization. After being minimally processed, samples were packaged in protective atmosphere (air and 100% O2), using a semi permeable film. Aim of the present work was to verify the effectiveness of the packaging in protective atmosphere on broccoli shelf life, storing the samples at 4+or-1 degrees C until 10 days. The influence of the presence and the absence of the sulphuric fertilization on leaves samples quality, in terms of nitrate and chlorophyll contents, colour, pH, TSS, and dry matter were assessed. Moreover, the attention was turned on the different fertilization influence on organic volatile compounds that, present in the headspace of the packages, determine the characteristic odour of the product, noticed in particular after the cooking phase.
