Abstract

The objective of this was to investigate the technical feasibility of producing toxicant-free by germination. To this end, rapeseed(Brassica napus L.) was germinated at $25^{\circ}C$ for 120 hours, and the chemical compositions of amino acids and vitamins were determinated in every 24 hours during germination. The results obtained are summarized as follows: Before germination, rapeseed contained 5.4g/16g N of glutamic acid and high percentage of the other amino acids in order of Asp>Leu>His>Pro>Arg>Lys>Gly>Ser>Ala>Val. The amino acids were gradually decreased until 96 hours during germination had tendency to show a slight increase in 120 hours. Vitamin B$_1$, B$_2$and C contents in rapeseed before germination were found to be 0.11, 0.21 and 3.72mg% respectively, and the vitamin E was 423ug/g. The vitamin C greatly increased in 72 hours during germination, while the vitamin B group was drastically decreased in 72 hours. The results obtained by this method clearly demonstrate that germination process is very effective to the removal of toxicants in rapeseed.
