Beside marine fish some oilseeds also contain polyunsaturated fatty acids. Eating habits of people are very difficult to change, so it makes sense changing the composition of fat through the diet of food animals for dairy and meat production. In a broader research we want to investigate a possibility of false flax inclusion in the diet of farm animals. But, first of all it is necessary to find suitable varieties for cultivation of this oilseed crop in our soil and climatic conditions also on a large scale, in terms of providing suitable yield. Variety trial was conducted in 2012 at four locations (Prekmurje and Savinja valley and on different soil). Included varieties were: Danish Vega and Hoga, German Calena, Bio Calena and Ligena and Slovenian autochthonous variety. Location had a significant impact on the yield of false flax. Positive impact in 2012, which was rather dry year with high temperatures, had higher soil water capacity. Variety Vega reached the lowest and variety Ligena the highest yield, followed by Bio Calena and Calena. The crop showed rapid, sudden maturation in the conditions of high temperatures and dry air; husks started popping suddenly, resulting in loss of seeds. Also, for false flax production there are no registered pesticides for the control of weeds, diseases and pests in Slovenia which presented noteworthy production problem.

Camelina sativa is an alternative, low input oilseed crop with oil of high nutritional value. In Slovenia, C. sativa landrace has been grown by local farmers in the Koroška region since the middle of the 20th century. In our study, we determined oil and glucosinolate content (GLS) of camelina seed and free fatty acid (FFA), peroxide value (PV), iodine value (IV), tocopherol contents (T), and fatty acid profile of camelina oil from ten locations over three consecutive growing seasons. The oil content ranged from 28.78 to 40.21%, while IV, PV, and FFA fell into a range that makes this oil useful in various nutritional applications. Camelina was remarkably rich in essential n-3 α-linolenic acid (33.32–37.65%) and γ-T(532–798 mg/kg) in oil, and GLS (16.39–41.43 mmol/g) in seed.

The purpose of this work was to characterize and quantify sterols in camelina sativa and pumpkin seed oils, as representatives of traditional vegetable oils of the continental part of Slovenia, where during the processing roasting and hot pressing is used. For research work, we used Camelina sativa and pumpkin seed oil of different geographical origin and varieties. Free sterols were extracted from samples of oil with solid phase microextraction (SPME). Purified chloroform extracts were then analyzed by gas chromatography (GC). Identification of individual sterols was carried out by comparison with standard compounds, and quantification using internal standard betulin. The results confirmed the differences in the incidence and quantity of the particular sterols between oils. In addition, the results also show the high dependence on the composition of geographical and varietal origin within each type of oil.
