This work aims at investigating the effects of pulsed electric field (PEP) on the extraction of polyphenols and proteins from rapeseed (Brassica napus L.) stems and leaves. The PEF (0.2-20 kV/cm) was applied on fresh rapeseed stems (diameter, d = 6 mm; thickness, h = 10 mm) and leaves (surface,S= 10 x 10 mm(2)).The PEF-induced cell membrane damage (Z) of rapeseed tissue was studied. The PEF (5-20 kV/cm) increased the extraction of total polyphenols from rapeseed stems and leaves. Treatment at 5 kV/cm resulted in the highest polyphenols purity. In addition, the data evidence that the polyphenols content in rapeseed stems and leaves decreased (approximate to 74%) as plant maturity advanced while the change for protein content is more gentle (approximate to 35.6% decrease). Results of the maturation effect may be useful to determine the optimum harvest time for the rapeseed by-products valorization. (C) 2015 Published by Elsevier B.V.
