    Mixograph를 이용하여 반죽의 물성에 미치는 화학첨가제의 영향을 조사한 결과 ammonium ferric citrate와 ferric sulfate는 0.1% 수준에서는 밀가루 반죽의 탄성에 뚜렷한 영향을 미치지 않았으나, MgSO $_4$ , CaCl $_2$ 및 ZnO는 반죽의 탄성을 증가시키며 최적반죽시간을 연장시켜 반죽 시간이 길어졌다. 그러나 Ca과 Mg을 각각 갖는 calcium citrate와 MgCl $_2$ 는 반죽 시간이나 탄성에 뚜렷한 영향을 나타내지 않았다. 빵의 부피에 미치는 영향은 0.1% MgSO $_4$ 와 CaCl $_2$ 가 브롬산 칼륨을 전혀 첨가하지 않은 대조구보다 부피 팽창이 더 커져서 브롬산 칼륨과 같은 팽창제로서의 기능을 확인하였으며, 이들을 첨가한 빵의 속과 겉껍질의 색은 모두 대조구보다 더 밝아서 첨가한 화학첨가제들이 빵의 색을 밝게 하는 것을 확인할 수 있었다. 밀가루의 내재된 효소를 불활성화 시키기 위하여 볶음처리와 UV 및 microwave 조사된 밀가루는 최적 반죽시간을 초과하여 계속 반죽하여도 최적반죽시간 후 반죽의 탄성저하현상이 처리하지 않은 대조구에 비하여 감소되어 반죽의 안정성이 향상되었으나, 열처리한 밀가루로 제조한 빵은 부피가 대조구에 비하여 적었으므로 열처리는 반죽의 안정성은 향상시킬 수는 있으나 빵의 부피 증가에는 효과적이지 못하였다.


    Effects of various chemical additives and heat treatments were investigated on the wheat flour doughs and breads. Ammonium ferric citrate, Ca-citrate, CaCl $_2$ , FeSO $_4$ , MgCl $_2$ and ZnO were mixed respectively to the flour up to 0.1% of flour dry weight basis. Ammonium ferric citrate and ferric sulfate showed no significant effects on the dough properties and magnesium sulfate, calcium chloride and zinc oxide increased elastic properties and optimum dough mixing time. However, calcium citrate and magnesium chloride showed no significant effects on the dough mixing properties. Most of chemicals were detrimental on the bread volume except MgSO $_4$ and CaCl $_2$ . Breads with MgSO $_4$ and CaCl $_2$ retained the equal or slightly higher volume compared to control bread. Crumb and crust colors of breads with addition of chemicals were changed to lighter than that of control bread. L values both of crumb and crust increased with addition of chemicals except Ca-citrate. To inactivate the endogenous enzymes of flour, flour was roasted under electric oven, exposed to UV and microwave. Those heat treatments of flour increased dough stability and produced no dough breakdown after optimum mixing time. However, bread volume of heat-treated flour decreased.
