Bread is the major food for a lot of peaple in the world and breadmaking is too long and needs skill. Also, Bread is a food product with short shelf life so for eliminating these problems released frozen bakery products. The freezing of bread dough, despite of its advantages has some disadvantages like decreasing of bread volume, expediting staling and destruction of product finl texture. The purpose of this research is to investigate the effect of Sodium Stearoyel 2-Lactilat emulsifier (SSL) and whey protein concentrate (WPC) for improving quality and staling of the bread from frozen dough. Therefore, SSL was used at 0, 0.4, 0.8 % and WPC at 0, 3.75, 7.5 % levels using central composite design. Dough samples were stored at -18°C for 1 month and the effect of adding the mentioned substances on bagguette bread quality properties was investigated. The results of tuxture profile analysis showed significant effect in the level of 1% about the amount of force applied on bread (P<0.01). Also the results indicated significant effect on increasing spesific volume (P<0.01) and overall admission on sensory evaluation of the bread (P<0.05). In this research, %0.5 SSL and %3.8 WPC was selected as the best treatment after optimizing results by response surface methology.
