연자육 분말의 첨가량에 따른 식빵 반죽의 물리적 특성을 알아보기 위하여 연자육 분말을 첨가한 반죽의 팽창력, ferinogram, amylogram, extensogram, 반죽의 pH와 식빵의 외관 등을 조사하였다. 연자육 분말의 일반성분 함량은 수분 7.74%, 조단백질 20.15%, 조지방 2.11%, 조회분 4.34%, 조섬유소 2.78%이였다. 반죽의 팽창력 결과 대조구에 비해 연자육 분말 첨가구가 팽창력이 좋았으며, 반죽의 farino

This study investigated the rheological properties of bread dough supplemented with lotus (Nelumbo nucifera) seed powder. The rheological properties measured were dough volume, farinogram, amylogram, extensogram, pH and outernal. The lotus seed powder contained 7.74% moisture, 20.15% crude protein, 2.11% crude fat, 4.34% crude ash, and 2.78% crude fiber. The farinogram showed that with increasing concentration of lotus seed powder the absorption rate of the dough increased slightly, the development time and stability decreased, and the degree of attenuation tended to be grown along. From the amylogram it was found that the gelatinization onset temperature and the maximum viscosity of the dough tended to increase with increasing content of lotus seed powder. The extensogram showed that the degree of extension of the dough decreased with increasing content of lotus seed powder, while the degree of resistance and resistance/extensibility increased. The dough pH tended to decrease with fermentation time, but increased with increasing content of lotus seed powder. A concentration of lotus seed powder appears to be suitable for the preparation of dough.
