The approach from “the natural” perspective of food contributes to providing qualitative food products which satisfy the requests of the living cell homeostasis. In this area the vegetable oils are considered responsable, and that they can be, at a certain point of their existence, raw material, as well as finite product; important sources of essential fatty acids, that through various ways of separation which form the “skeleton” of the technologies of oil industry (cold pressing, extracting) are brought to an easily assimilated form by the human body. In the last years, the vegetable oils industry became highly attractive through the development of the newest technologies and/or through the rediscovery of the minimum processing technologies (environmently friendly, green technologies) through which some more “humane” products are obtained, easily assimilated by the human body and with increased biological activity potential. The consumer, through these information, is heading towards the consumption of vegetable oils resulted from cold pressing, persuaded by the beneficial aspects generated by the unsaturated compounds and especially of those polyunsaturated, resulted without the intervention of the chemical compounds. This constitutes an important element that characterises nutritional, structural, sensorial and functional performances of a food. The access of these “green” technologies (cold pressing) even if the extraction efficiency are poorer (absent from the technological flux of implication of exhaustive chemical reactions, that have high energy consumption and that emit effluents into the environment), but through the beneficial nature of the obtained products, contributes to a higher consumption. Also the resulted material has applications and diverse uses (pharmacy, cosmetics, medicine, food supplements etc.).
