For over 3000 years, people have eaten touchi as a preserved food or used it for seasoning.The Touchi extract has a property to inhibit the activity of alpha-glucosidase. In other words, in the presence of the Touchi extract, glucose and fructose are hardly produced from maltose and sucrose at the small intestine. Thus, absorption of carbohydrates or sucrose through the small intestine is markedly retarded, which accounts for the fact that the Touchi extract inhibits the rise of blood sugar level after meal which otherwise would result. Moreover, in the presence of the Touchi extract, carbohydrates or disaccharides remaining undigested are excreted outside the body: as a result, absorption of carbohydrates or disaccharides is inhibited and the blood glucose level is kept low.
The Touchi extract inhibits the activity of alpha-glucosidase, which accounts for the reduced absorption of carbohydrates or disaccharides into body. Thus, the Touchi extract not only directly keeps the blood glucose at level low but removes some causes leading to obesity. In the latter aspect, the Touchi extract further contributes to the cure of diabetes. This property to inhibit the activity of alpha-glucosidase is found only in the bean that has been fermented with Aspergillus sp, and not in raw bean, boiled bean, bean whey, nor boiled bean fermented with a strain of Bacillus subtilis natto (ˇ°Nattoˇ±, Japanese traditional appetizer). The experiment showed that this effect exists only in the Touchi extract.
Function:
1. Touchi extract showed Anti-glycaemic effect in rats;
2. Touchi extract also showed Anti-glycaemic effect in a clinical trial on borderline diabetic subjects;
3. Anti-glycemic effect of Touchi extract in humans;
4. Anti-glycemic effect of Touchi-extract;
5. Anti-lipidemic effect of Touchi-extract. |
