Abstract

In this work a process for obtaining high vitamin E and carotenoid yields by supercritical carbon dioxide(SC-CO2) extraction from pumpkin (Cucurbita moschata Duch.) is described. The results show that the useof a vacuum oven-dried [residual moisture (8%)] and milled (70 mesh sieve) pumpkin flesh matrixincreased SC-CO2 extraction yields of total vitamin E and carotenoids of 12.0- and 8.5-fold,respectively, with respect to the use of a freeze-dried and milled flesh matrix. The addition of milled(35 mesh) pumpkin seeds as co-matrix (1:1, w/w) allowed a further 1.6-fold increase in carotenoidyield, besides to a valuable enrichment of the extracted oil in vitamin E (274 mg/100 g oil) andpolyunsaturated fatty acids. These findings encourage further studies in order to scale up the processfor possible industrial production of high quality bioactive ingredients from pumpkin useful in functionalfood or cosmeceutical formulation.
