摘要
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。
The defecation and fecal water content were increased in rats when treated with gastric intubation of 0.5,0.8 or 1.2g multifunctional soybean fiber(MSF)/kg body weight every day.The greater dose of MSF,the more obvious effects on defecation,but not so obvious on fecal water content. 0.8g wheat fiber/kg body weight took the similar effect. The same dose of pectin also took obvious effect on the increase of fecal water content, but no obvious effect on dry fecal weight. Soluble dietary fibers with higher water-holding capacity are more liable to be degraded by bacteria in the large intestine than insoluble dietary fibers, which lead to more obvious effect on fecal water content but less obvious on dry fecal weight. The effects of insoluble dietary fibers are just the opposite.
