铁阳锌缺乏是当前我国较为普遍存在的营养问题,而黑米中的铁、锌、铜含量高于白米,黑米糠中的铁和锌又为黑米仁的二十多倍,黑米糠中的铁能否被机体利用及其可利用的程度,采取某些改善措施后,能否提高黑米糠中铁的生物利用率是本研究的主要目的。实验方法采用国内外公认的血红蛋白恢复法,首先复制贫血模型,用雌雄各半的幼大鼠48只,喂以低铁饲料,含铁量为<10ppm,在无铁环境中饲养,每周测定Hb含量,直到Hb达贫血要求为止。然后,按贫血大鼠的Hb和体重将动物分为甲、乙、丙、丁、戊五组,在低铁基础饲料的基础上,各组依次补充FeSO_4·7H_2O、
Tieyang zinc deficiency is currently more common in our country nutrition problems, and black rice in the iron, zinc, copper content is higher than white rice, black rice bran in iron and zinc and black rice kernels more than twenty times, black rice bran Of iron can be used by the body and its availability, to take some measures to improve the bioavailability of iron in black rice bran is the main purpose of this study. The experimental method is based on the hemoglobin recovery method recognized both at home and abroad. Firstly, the anemia model was replicated. Forty-eight male and half young rats were fed with low-iron diet containing less than 10 ppm iron and kept in an iron-free environment. Hb content, until Hb reaches the anemia requirements. Then, according to the Hb and body weight of anemic rats, the animals were divided into A, B, C, D and E groups. On the basis of low iron basic diet, the animals were fed with FeSO 4 · 7H 2 O,
