The objective of this study was to investigate the technical feasibility of producing toxicant-free rapeseed by germination. To this end, rapeseed (Brassica napes L.) was germinated at 25℃ for 120 hours, and the compositional changes of fatty acids and minerals were determined in every 24 hours during germination. Repeseed slightly decreased it´s fat content during germination, whereas it showed a tendency to increase protein content. The contents of oleic, erucic, linoleic, linolenic, stearic, palmitic and arachidic acids in rapeseed before germination were found to be 24.6, 15.5, 10.6, 9.5, 1.0, 2.4 and 5.3 respectively. They were gradually decreased until 96 hours and showed a slight increase in 120 hours during germination. However, there was no significant difference in the variation of fatty acids composition in rapeseed during gemination. The content of minerals-phosphorous, calcium, magnesium, zinc, manganese, copper and iron-in rapeseed before germination were 6367, 3068, 2667, 80.3, 26.5, 15.9, and 94.4 ppm respectively and sodium was detected in trace. The mineral contents in rapeseed were gradually decreased in the early period of germination, but showed a slight increase in 120 hours.
