Effects of Mulberry Leaf Powder on Physicochemical Properties of Bread Dough

This study was carried out to investigate the physicochemical properties of bread dough with added mulberry leaf powder. The crude protein, fiber and ash contents of the mulberry leaf powder were 21.25%, 7.70% and 9.27% respectively. The mulberry leaf-mixed powder showed low lightness and redness values and high yellowness. Farinograph water absorption increased as the mulberry leaf powder content increased. Both arrival and development times of the mulberry leaf powder-added dough were longer than those of wheat flour dough. As the mulberry leaf powder content increased, the degree of weakness increased. Maximum viscosity by amylograph analysis increased gradually with the addition of mulberry leaf powder, while gelatinization temperature was not affected. Degree of extension decreased as shown in extensograph analysis with increasing content of mulberry leaf powder.
