Impact of conditions of the heating of flax and false flax seeds on the characteristic of oils for the biodiesel production
Summary.

The aim of the study was to determine the impact of diverse heating condition of the flax and false flax seeds on the pressing yield and characteristics of oils as potential materials for the biodiesel production. Seeds were heated in three different temperatures (60, 80 and 100°C) over the period of 30, 60 and 90 min. Then using a laboratory screw press the oil samples were extruded from the heated seeds. The quality of oils was determined after the determinant of the water and volatile matter content, the degree of hydrolysis and oxidation, phosphorus and chlorophyll content and fatty acid composition. It has been shown that an increase in temperature and time of heat treatment contributed a gradual increase in pressing yield and deterioration of the quality of the oil samples. The most preferred heating conditions of flax and false flax seeds for the production of biodiesel, due to the high pressing yield and a small changes in quality of oils, were temperature of 80°C and 60 min.

Key words: flax, false flax, heating, pressing, oil quality, fatty acid composition
