Utilization of winery by-products into high added value products – grape seed oil and defatted meal

The aim of this study was to use waste from the wine production process with special accent on grape seeds variety Graševina and Zweigelt and new green technology. Supercritical CO2 was considered as a green solvent in extraction of grape seed oil because it has been proven to be highly desirable solvent in separation processes since it is non-toxic, non-flammable, odorless, tasteless, inexpensive and readily available in large quantities, and because it is an environmentally friendly solvent. The results of this study show the possibility of utilization of grape seeds from wine pomace for the production of good quality grape seed oils with high processing yields.
