魔芋精粉减肥的实验研究

从魔芋中提取出来的魔芋精粉是富含葡萄甘露聚糖的膳食纤维,只含很少的蛋白质和极低的能量。将出生24天的SD大鼠分为三组,均喂以高脂肪高营养饲料,第一组为对照组;第二、三组的饲料中每天分别加入1.9mg/g体重和19mg/g体重的魔芋精粉。45天后得到下列结果:1.魔芋组的体重增长低于对照组;2.对照组鼠脂肪组织的重量及脂肪细胞大于魔芋组,说明魔芋有明显的减肥作用;3.三组间血清胆固醇、甘油三酯和某些元素水平无明显差异,4.魔芋组鼠的粪湿重大于对照组;5.实验中未发现不良作用。

AN EXPERIMENTAL RESEARCH ON THE ANTI-OBESITY EFFECT OF KONJAC FLOUR

The Konjac flour (KF) was from Amorphallus Konjac, a kind of food, rich in dietary fibre composed mainly of gluco-mannan, but trace protein and very low energy.Male and female Spraue-Dawley rats aged 24 days were divided into 3 groups. All 3 groups were fed with high lipid and high nutrition diet. The group A was set as control, group B and group C plus KF in diet daily oral dose of 1.9mg/g and 19mg/g body weight respectively.After 45 days feeding, the following results were obtained;1. The increases of body weight in rats were reduced by oral KF.2. The size of fat cells in abdominal tissue and fat weight were greater in control group than in the other groups. These results suggest that KF has a significant effect on reducing obesity.3. No significant differences were found among the three groups in serum of chol, TG and some elements.4. The moist faeces in the KF groups were greater than the control group5. No side effects were found on the tests.
