2.2. Formulations of cookies
For the production of white supplemented cookies, blends of wheat flour type 400 and the supplements were prepared by substituting wheat flour with crushed sunflower seed at 10 g/100 g and 30 g/100 g levels or at 30 g/100 g and 50 g/100 g with barley flour. A blend of wholegrain and white wheat flour, at a proportion of 50:50, was used as a basis for the preparation of wholegrain cookies. Similar to the white cookies, the wholegrain-white flour blend was mixed with crushed sunflower seed at 10 g/100 g and 30 g/100 g on a substitution basis or 30 g/100 g and 50 g/100 g with barley flour. In order to evaluate the contribution of the supplements, the control cookies of white and wholegrain wheat flour, without any supplements, were made.
The cookies were prepared by mixing 500 g of prepared blends of flour and the tested ingredient with 150 g of sugar, 150 g of margarine, 10 g of salt and 2.5 g of baking powder in a kitchen mixer equipped with a spiral hook. The water was added in an amount to produce dough with acceptable handling characteristics. Dough consistency and stickiness were subjectively estimated by an experienced baker. The dough was rolled on a pastry board to a uniform thickness of 6 mm and cut into 5 cm diameter rounds. Cookies were baked at 180 °C for 10–15 min.
