A physico-chemical characterization of oil from Camelina sativa seeds grown in Romania

It is well-known that camelina oil, obtained from Camelina sativa seeds is rich in fatty acids, predominantly linolenic acid and is used successfully in pharmaceutical and cosmetic therapies. It is remarkable that this species has a great adaptability to environmental conditions, being able to cultivate it on agricultural parcels and polluted soils. The goal of this work is to evaluate the quantitative and qualitative differences of three types of camelina oils, obtained from varieties grown in Romania: GP 202-Spanish provenance, Camelia and Madalina, both Romanian provenance. The effect of soil fertilization on the quality of the seeds /oil obtained from 3 varieties of camelina was tested, the control being the unfertilized Camelina variety. The following parameters have been evaluated: seed moisture, cold oil extraction yield, certain physico-chemical oil indicators and percent quantitative composition of individual and total fatty acids. Remarkable is the total fatty acid content of the oil that varies between 75.87 g% for the unfertilized Madalina variant and 81 g% for the fertilized GP-202 variant. Taking in consideration the results for all the studied parameters, it can be concluded that the Mack Vinci variety is very similar to the other two, and fertilization contributes insignificantly to the improvement of the quality of the obtained oil.
