0.5、0.8或1.2g/kg·d的多功能大豆纤维(MSF),可增加小鼠粪便排泄量及粪便含水量。当MSF剂量增加时粪便排泄量随之增加,但粪便含水量无明显变化。0.8g/kg·d小麦纤维的作用相似,而同剂量的果胶也可明显提高粪便含水量,但对粪干质量无明显影响。水溶性纤维的持水力高,易被大肠微生物所降解,对增加粪便水分含量的效果较好,但对增加粪干质量的效果较差;水不溶性纤维的作用恰好相反。 0.5, 0.8 or 1.2g / kg · d of multifunctional soybean fiber (MSF), can increase mice excretion and fecal water content. Excretion of faeces increased with an increase in MSF dose, but no significant change was observed in fecal water content. The effect of wheat fiber of 0.8g / kg · d · d was similar. However, pectin at the same dosage could significantly improve the water content of feces, but had no significant effect on the quality of feces. High water-holding capacity of water-soluble fiber, easily biodegradable coliform microorganisms, to increase the effect of stool water content is better, but to increase the quality of the fecal stem is less effective; the role of water-insoluble fibers on the contrary.
