Abstract

The article presents the results of a study of non-traditional oilseeds of the family Brassicaceae (camelina, crambe) and the Asteraceae family (safflower, ramtil) in the Middle Volga region. The crop productivity was studied, which was high and varied in the range of 1.35–2.77 t/ha. The oil content in the seeds ranged from 28.3 % in safflower to 43.1 % in crambe. The fatty acid composition of these crops is used for various applications. A high content of erucic acid of 59.3 % was noted in the oil seeds of crambe, 2.92 % in the seeds of camelina. A high content of erucic acid (58.9 %) in the oil of crambe allows it to be used for the production of biodiesel. A sufficiently high content of linolenic (35.6 %), oleic (13.7 %) and a low content of erucic (up to 3.1 %) acids allows using camelina oil for food purposes. The content of erucic acid in safflower oil is reduced to trace values 0.03 %, which allows it to be attributed to valuable edible oils. The fatty acid composition of ramtil oil seeds is represented by a high content of linoleic acid (79.3 %). Ramtil oil can be considered as a valuable source of omega-6 essential fatty acids.
