Abstract:
Trypsin, chymotrypsin and amylase levels were determined in the pancreas, all along the intestinal tract, and in the feces of rats fed raw or heated soy flour diets. The levels of all enzymes measured in the pancreas in the non fasted state were lower in the raw than in the heated soy flour fed rats. Fasting equalized these levels. Trypsin and amylase tended to be lower, and chymotrypsin was significantly higher in the intestinal tracts of raw soy flour fed rats than in the group fed heated soy flour; the greatest differences were found in the ileum. Trypsin and chymotrypsin levels in the feces were higher in the group fed raw soy flour than in the group fed heated soy flour. Amylase in the feces of the raw soy flour fed rats was higher at the beginning of the experiment and dropped sharply to be even lower than in the heated soy flour fed rats at days 13 to 14 of the experiment. It was concluded that measuring the enzymic levels in the feces is a very sensitive method for determining whether a test diet induces hypersecretion of digestive enzymes in rats. This method can be used from the start of feeding the experimental diet. As the animal need not be killed, the effect of the test diet upon enzymic secretion can be studied as a function of time, and it might be suitable to studies with large animals.
