## 1 Introduction  
Recently, there has been a significant increase in consumers' interest in low-processed food of high nutritional value. These products include cold-pressed oils, which are obtained not only from many typical oilseeds, such as sunflower, rape, and flax, but also from less known sources, e.g., borage, milk thistle, poppy, pumpkin, and camelina seed (_Camelina sativa_ L.). Camelina is an oily plant belonging to the _Brassicaceae_ family, also known as false flax, gold-of-pleasure, leindotter or camelina. _Camelina sativa_ was already being cultivated around 3000 years ago. The history of camelina cultivation in Europe dates back to the Bronze Age, and the minimal climatic and soil requirements made the plant very popular in many countries--Russia, Ukraine, Croatia, the Czech Republic, Germany, Austria, Switzerland, Poland, England and Hungary. However, since the middle of the nineteenth century, camelina began to be replaced by other oilseeds [1; 2; 3; 4]. In recent years, the interest in this plant has been growing again, though. Camelina is used as a rich source of essential \(n\)-3 \(\alpha\)-linolenic acid in the production of health-promoting foods and supplements [2; 5], as animal feed (for cows, chicken-broilers,turkey, sheep and fish) [5; 6; 7], and as feedstock for biodiesel manufacture and jet fuel [8; 9], as the crop is low-input, and hence economical to produce [1; 10; 11; 12; 13]. Camelina is a short-season crop (the vegetation period of the plant lasts from 85 to 100 days). Therefore, it is ideal for growing in temperate climates. Soil requirements are also not demanding, so amelina can be cultivated on soils with a low nitrogen content--semiarid, marginal and saline soils. The crop is also resistant to pests; therefore, it does not require the use of a large amount of plant protection products [3; 4; 10; 11; 14]. _Camelina sativa_ L. seeds contain about 33-47% fat [1; 2; 11; 12]. The high nutritional value of amelina oil is primarily related to its fatty acid profile. It contains only about 10% saturated fatty acids (SFA), mainly palmitic (16:0), stearic (18:0) and eicosanoic (20:0) acids. Oleic (18:1) (14-16%) and eicosenoic acids (20:1) (12-15%) are predominant in monounsaturated fatty acids. Over half of the total fatty acid pool is constituted of polyunsaturated fatty acid (PUFA), of which the highest proportions are \(\alpha\)-linolenic acid (ALA) (18:3) (31-40%) and linoleic acid (LA) (18:2) (15-23%). Of particular importance is the high content of ALA, which is considered an \(n\)-3 essential fatty acid, and whose supply in the diet is very often insufficient. \(\alpha\)-Linolenic acid is very important in the prevention and treatment of cardiovascular diseases, hypertension, and in ensuring proper vision and the general functioning of the human organism [15; 16; 17]. In addition, [PERSON] et al. [18] showed that _Camelina sativa_ L., upon consumption, may exert anti-obesity and antidiabetic effects, and may also inhibit human low-density lipoprotein (LDL) oxidation and DNA damage induced by peroxyl and hydroxyl radicals. The seed extracts of amelina showed significant antioxidant activity and effectively inhibited pancreatic lipase and \(\alpha\)-glucosidase activities. These enzymes in the digestive tract are associated with lipid and carbohydrate digestion, respectively, and control obesity and blood glucose level in the human body. The nutritional benefits of amelina oil have been known and appreciated for many years, as demonstrated by its use in herbal medicine (for wounds, treatment of burns, stomach ulcers, and eye inflammations). The plant is often recommended as a dietary oil to supplement deficiencies of the \(n\)-3 acids family [1; 2; 3; 4; 19; 20; 21]. Cold-pressed amelina oil is also rich in non-glycerols--the content of tocopherols varies between 55.6-99.4 mg/100 g [3; 4; 18], and sterols from 360 to 590 mg/100 g [19; 22].
