Investigation of Physicochemical properties of semolina made from some hard wheats and the cooking quality of their dough products

Dough products are traditional and inexpensive food products that their consumption has increased. Unfortunately in our country due to lack of adequate cultivation of durum wheat, lack of appropriate technology for the production of durum wheat semolina and economic conditions for import of durum wheat, producing high quality dough product is faced with many problems. Also the price of durum wheat is more expensive than other wheat cultivars. In order to provide Dough products with good quality, in this study we investigate physicochemical properties of semolina and cooking qualities of dough products made from three different varieties of hard wheat namely Morvarid, Chamran, Sayson and two breeding lines namely A-line and N-80-19 line that are easy available in Iran. Behrang durum wheat is used as reference variety. Some strong relationships exist between semolina characteristics such as protein, wet gluten, gluten index and dough product quality. Finally the results show that Chamran and N-80-19 cultivars based on key features of dough product (yellow color, protein content and cooking quality) have no significant difference with control sample and they can be introduced as the best wheat to dough products industry.
