Abstract

The purpose of this research is to study the nutritional effect in growing rats by feeding the heat-treated soybean diets.
The experimental animals were eighty-four male albino rats weighing between 100-120gm, and were divided into four groups according to the following experimental diets; standard diet, raw soybean diet, heat-treated soybean under 100˚C diet and 120˚C diet for 30 days.
After the feeding, the weight gain of the body is observed and the amounts of total nitrogen, cholesterol, hemoglobin, hematocrit, sulfhydryl group, and activities of GOT, GPT, dipetidase of intestine and trypsin in pancreas were also measured.
The results obtained are summarized as follows:
1. The total net weight gain of the body in the soybean feeding groups is lower than that of the standard diet group but the one with the heat-treated soybean under 120˚C is a little better.
2. The total nitrogen content in the liver of raw soybean feeding group is lower than that of the standard diet group.
3. As far as the total nitrogen content in pancreas concerened there are no differences in each group.
4. The total cholesterol content in liver of the heat-treated soybean under 100˚C fed group is increased than that of the standard diet group for the first 5 days feeding period, but it is decreased for the 15 days and 30 days feeding period.
5. There are no significant differences of the total cholesterol content of serum in each diet group.
6. There are no significant differences of the hemoglobin and hematocrit contents in blood in each diet group.
7. The sulfhydryl group content in the liver of the heat-treated soybean diet group is higher than that of the raw soybean one´s on the 15 day feeding diet group.
8. The GPT activity in the liver and serum of the soybean feeding group is higher than that of the standard diet group.
9. The GOT activity in the liver and serum of the standard diet feeding group is generally decreased than that of the soybean feeding group.
10. The trypsin activity in the pancreas of the 100˚C heat-treated soybean feeding groups is higher than that of the raw soybean feeding group.
As the result of those obsrvations, it can be stated that the net weight gain of the body is better than those of heat-treated soybean fed gorup while the sulfhydryl group content and the enzymatic activities, etc. in the content of those structual elements, the heat-treated groups are substantial than those of the raw soybean group.
