Studii privind uleiul extras din seminţe de struguri, aparţinând unor soiuri diferite de Vitis vinifera

Abstract

The grape seed oil is a vegetal oil obtained from different varieties of Vitis vinifera, a product that results from the waste of wine industry. Though it is known by the europeans from centuries, the grape seed oil was not produced untill the XX century, mostly because of the low content in oil, comparative to other oil plants. The most grape seed oil is made in Italy, but also in France, Spain, Argentina. In our country, the grape seed oil was made for the first time in 1953, from the seeds of cooperativized sector of viticultural and from the private persons. The high content in oil matter justifies the separation of the seeds from the pressed grapes and their using as row material for the oil seed making. The grape seed oil is obtained either by pressing operation and the productivity is 4-5% or by extraction with solvents and the productivity is 8-15%.
