説明
Weaning rats were fed diets containing 59% starch granules, 25% casein, 5% corn oil, 5% fiber, and adequate quantity of minerals and vitamins for 4 weeks. Growth responses of rats to four kinds of starch granules were as follows; high-amylose corn≤ potato<yamanoimo<corn. In vitro digestibility of these starch granules to pancreatin was as follows; potato<yamanoimo≤ high-amylose corn<corn. Starch granules were separated from feces and contents of stomach, intestine (small and large) and cecum of rats fed each one of diets containing starch granules as the main carbohydrate source and observed under a scanning electron microscope (SEM). On the surface of potato and yamanoimo starch granules isolated from stomach of rats, shallow holes were observed under SEM and supposed to be results of the attack by salivary amylase. Many pin holes, in small and large size, were observed on the surface of potato and yamanoimo starch granules isolated from feces and contents of intestine and cecum, and sometimes step-shaped or terraced inner structures of starch granules could be seen. These observations suggested that starch granules of potato and yamanoimo were attacked by a-amylase (s) of gastrointestinal tract of rats including those of entero-microorganisms. SEM observations of the cross-section of a grain of feces of rats fed each one of diets containing starch granules of potato, yamanoimo, and high-amylose corn revealed that damage of starch granules could be seen without the tedious procedure separating starch granules from feces.*1 To whome requests for reprints should be addressed.
