Chem. Listy, 102, s265–s1311 (2008) Food Chemistry & Biotechnology<br />

during the storage, our mean value (0.0068 mg MDA kg –1 )<br />

showed the stability in oxidative changes (Table I).<br />

The highest representation of fatty acids was found<br />

at oleic acid content (61.658 %), followed by linoleic acid<br />

(24.112 %) and linolenic (6.690 %). Mean content of erucic<br />

acid was found 0.399 %.<br />

Conclusion<br />

Storage conditions affect quality of raw materials. We<br />

can conclude that during observed years were not found any<br />

important oxidative changes in fat of rapeseed, seems due to<br />

optimal conditons during its storage.<br />
