식빵을 제조할 때 솔잎의 당 발효액을 설탕 대용으로 사용하면서 솔잎의 기능성을 제빵에 이용하고자 솔잎발효 액을 첨가하여 반죽에 대한 물성을 측정하고, 빵을 제조 후 실온에 저장하면서 제품의 품질 변화를 보았다. farinogram에 의한 반죽의 물성 평가에서 반죽에 대한 안정성과 혼합 내구성에서 설탕을 함유한 반죽보다 솔잎발효 액을 첨가한 처리구가 우수한 것으로 평가되었다. 또한 반죽의 발효에 영향을 미칠 수 있는 pH에서도 솔잎발효액 첨가 구에
In efforts to use pine needle extract as a substitute for sugar, fermented pine needle extract syrup was added to the wheat flour nea in the manufacture of white bread The extract was added to levels of 8.3%, 11% and 18% of total weight based on the Brix degree of the dough The cohesion of each dough was checked, and the physical properties and storage stabilities of the baked breads were analyzed during storage at mom temperature. Analysis of the cohesion of each dough by farinogram showed that dough with pine needle extract was better than dough with sugar, in terms of both stability and durability of mixing. The pH of dough with syrup was steady during storage at pH 5.4 5.8, which is favorable for yeast activity. The dough with syrup also showed low firmness and good extensibility, both of which would favorably affect gas retention on fermentation. Increases in syrup addition resulted in higher product volumes. Bread with syrup was slow to increase in hardness during storage, suggesting that higher syrup concentrations inhibited development of staleness. The addition of syrup also inhibited the growth of aerobic bacteria and mold on the bread surface. The addition of syn did not cause any negative effect. The use of pine none extract syrup may thus contribute to improvements the physical properties, the storage stability, and the hygienic quality of bread.
