Unsaponifiables in the kernel and the cob of 7 maize varieties were analyzed by using thin-layer chromatography (TLC) and gas chromatography (GC) for the identification of phytosterols and their concentrations. The unsaponifiables of the kernel were clearly separated into band I (campesterol, stigma...

옥수수의 속대는 어떻게 이용되어 왔는가? | 그러나 이삭에서 종실(kernel)을 탈립 후 부산물로 남겨지는 속대(cob)는 그 용도가 다양하지 않아 사료 및 땔감 등으로 쓰였는데, 태우고 남은 재에는 알칼리성분이 풍부하여 칼리비료의 제조에 사용되기도 하였다. | |
옥수수 속대에 함유되어 있는 Phytosterol이란? | 우리나라에서는 민간요법으로 잇몸염증 완화에 옥수수 속대 끓인 물을 사용하여 왔으며, 최근 호주 등지에서는 속대 추출물이 첨가된 치약을 개발하였는데, 이는 속대에 함유된 phytosterol이 잇몸질환 예방과 치료에 효과가 있기 때문이라고 한다. Phytosterol은 각종 식물에 널리 함유되어 있는 steroid alcohol류의 물질로서 옥수수, 콩 등에 함량이 높은 것으로 알려져 있다(Rouf et al., 2016, Verleyen et al. | |
옥수수 속대를 이용해서 당을 얻거나 에탄올 생산에 사용하는 이유는? | 옥수수 속대에는 cellulose가 약 39.1%, hemicellulose 42.1%, lignin 9.1%로 풍부하게 함유되어(Barl et al. 1991) 있어 속대를 가수분해 또는 효소처리를 하여 arabinose, xylose, xylitol, xylobiose와 같은 당을 얻거나 lactic acid, citric acid, 에탄올 생산에 이용하고 있다(Beall & Ingram 1992, Liaw et al. 2008, Olsson & Hahn-Hägerdal 1996). |
