Green tea contains polyphenols with potent α-glucosidase inhibitory activity, such as epigallocatechin gallate (EGCG), and therefore, as a functional food ingredient, it is expected to inhibit carbohydrate absorption in the gastrointestinal tract and suppress blood glucose elevation. The addition of matcha, powdered green tea produced by grinding with stone mill, to sweet rolls that are rich in carbohydrates due to high flour and sugar content was hypothesized to suppress the elevation of blood glucose level observed after eating conventional sweet rolls. In this study, we developed a sweet roll containing matcha (hereafter, green tea sweet roll), and investigated the hypoglycemic effect of matcha in rats. Matcha strongly inhibited sucrose absorption, and it was estimated that 0.60 g of matcha has an effect that is 1/10 that of the control acarbose. Next, healthy human volunteers were served conventional (control) and green tea sweet rolls. At 45 min and 60 min after eating the sweet roll, blood glucose level were significantly lower in the green tea sweet roll group. These findings indicate that the addition of matcha to sweet rolls suppresses elevation of blood glucose.
