It is important to understand the benefits of an indigenous foodstuff containing carbohydrate in terms of glycemic. The glycemic parameters are the glycemic index (GI) and glycemic load (GL). Turkish Kahramanmaraş tarhana and Beypazarı cookie were used as indigenous foodstuffs. Because of delicious and high protein content, these foods are commonly used in Turkey. In this study, we realized the glycemic assessment of these foodstuffs by carrying out enzymatic hydrolysis of the carbohydrates containing in our simulated in vitro system. It was found that Kahramanmaraş Tarhana as used snack and soup have a low-glycemic index (<55) using Turkish white bread (TWB) as a reference carbohydrate. The GI values of Beypazarı Cookie and Turkish Kahramanmaraş Tarhana were determined as 62.8±2.8 and 53.1±2.4, respectively. The glycemic load (GL) values of both samples were bigger than 20. The values of these species will increase if their consumption is high.
