用放射性~(56)铁掺入高铁酵母,普通酵母与硫酸亚铁加~(59)铁以及单纯硫酸亚铁加~(59)铁灌胃大鼠,测定铁的吸收率。大鼠灌胃后,分笼饲养,连续收集三天粪便,经灰化定容后,测定放射性强度。实验结果表明,高铁酵母中铁的吸收率为38.7％,硫酸亚铁吸收率为38.3％,表明掺入酵母中的铁吸收率较高,与硫酸亚铁相似。高铁营养酵母富含铁、蛋白质和B族维生素,用于强化儿童食品,对于提高营养价值和预防儿童缺铁性贫血具有实际意义。
Radioactive iron (56) was used to inoculate rats with iron fermenters, common yeasts and ferrous sulphate plus ~ (59) iron and ferrous sulfate alone with ~ (59) iron. After gavage, the rats were kept in separate cages and the feces were continuously collected for three days. The radioactive intensity was determined after the ascites were fixed. The experimental results showed that the absorption rate of iron in high-iron yeast was 38.7% and the absorption rate of ferrous sulfate was 38.3%, indicating that iron absorption into yeast was high, similar to ferrous sulfate. High-speed rail nutrition Yeast is rich in iron, protein and B vitamins, used to strengthen children’s food, to improve the nutritional value and prevention of iron deficiency anemia in children with practical significance.
