| 摘 要： | 采用离体实验模拟人体胃和肠道的pH值条件,探讨了沙果膳食纤维对胆固醇和亚硝酸根离子(NO2-的吸附能力.结果表明,在体外模拟实验中,沙果膳食纤维对对胆固醇和NO2-的吸附效果与pH值有关.沙果膳食纤维在pH值为7.0中性条件下(模拟小肠的pH值环境)对胆固醇的平均吸附量为7.62mg/g,高于pH值为2.0酸性条件下(模拟胃的酸性条件)的5.80mg/g吸附量；沙果膳食纤维在pH值为2.0条件下对NO2-的吸附能力为1.21 mg/g,高于pH7.0条件下的0.85mg/g的吸附量.说明沙果膳食纤维具有明显的清除胆固醇和NO2-的效果,是一类高活性的膳食纤维. |

| Abstract: | The adsorption of cholesterol and NO2-on dietary fiber from Malus asiatica pomace(MPDF) was studied by in vitro test which simulated the pH of human gastrointestinal tract.The results showed that the adsorption capacity of Malus asiatica dietary fiber on cholesterol and NO2-was related with pH in vitro.Under pH value 7.0(simulating the pH of small intestine),the average adsorption capacity on cholesterol was 7.62mg/g,which was higher than that of 5.80mg/g under pH value 2.0(simulating the pH value of stomac... |
