Abstract
The transit of soybean oil through the gastrointestinal tract was studied in rats fed 4% pectin diet in comparision with those fed 4% cellulose diet. The structural changes of the surface of the small intestinal mucosa were also observed by scanning electron microscopy.
1. The ratio of lipid content in the feces of rats fed 4% pectin diet was higher than that of rats fed 4% cellulose diet.
2. The apparent lipid ahsorption ratio of rats fed 4% pectin diet was lower than that of rats fed 4% cellulose diet.
3. Rats fed 4% pectin diet showed irregular arrangement of the small intestinal villi, especially abnormal structure at the top of the villi.
