One of the most important stages of the technological process of extraction of target components from the seeds of the agricultural oil crops by the extraction method is extraction which lasts for the longest time, and therefore it actually determines, on the whole, the speed and economic efficiency of the entire process. The aim of the work was to study the extraction kinetics canola (rapeseed) (oilcake and whole grain) to determine the optimal technological parameters (kind of the extragent, hydromodule, value of the function) of the process carried out in a microwave field. As a result of the investigations of the concentration of the obtained oil, it was found that, in contrast to alcohol, the solvent hexane ensures a higher intensity of the process, a greater diffusion and solubility coefficient. However, the experimental research of the intensity of action of the solvents under the impact of the microwave field, and without it (at the temperature conditions of boiling solvents), showed that intensified action of ethyl alcohol (ethanol) during the extraction in a microwave field is 1.5 times more intensive than the action of hexane. The conducted investigations indicate that, in case oil is extracted from canola (rapeseed) under microwave field conditions, preference should be given to a polar, nontoxic and more safe (in contrast to hexane) solvent - ethyl alcohol (ethanol).
