영문 초록

Recent consumption of germinated brown rice is increasing due to its health-beneficial effects. To clarify germination-dependent changes in functional compound contents, 5 different types of (ordinary, glutinous, green-kerneled, red-colored and black-colored) rices were selected and their pre- and post-germination content changes in vita-min E (α-, β-, γ-tocopherols and α-, γ-, δ-tocotrienols), squalene, and phytosterols (campesterol, stigmasterol, sitosterol) were evaluated. In the case of vitamin E isomer contents, germination generally resulted in decreasing tendency around 10% in most isomers as well as in total tocopherol and tocotrienol contents in all types of rices. In the case of squalene, significant increase could be observed in glutinous rice (by 31%), while other types of rices exhibited no changes or slight reduction by germination. Regarding stigmasterol contents, all tested types of germinated brown rice exhi-bited significant increment by 19 to 27% compared to non-germinated cases, except for green colored-rice which showed statistically not significant 5% increment. No changes or slight reductions, however, could be observed in campesterol and sitosterol, as well as in total phytosterol contents. As a conclusion, most of tested pharmaceutical compounds exhi-bited statistically not significant changes except for stigma-sterol which were increased by the germination process.
