Abstract

Physicochemical, texture, and sensory properties of Jeung-pyun prepared with different concentrations of Monascus rubber DSJ-20 (Red yeast rice) were determined. Acidities and pH values of 3-5% M. rubber DSJ-20-treated groups were similar to those of control group. Degree of surface color increased in proportion to M. rubber DSJ-20 concentration. Hardness, gumminess, and chewiness of 1-2% M. rubber DSJ-20-treated groups were higher than those of control. Network structures of 3-15% M. rubber DSJ-20-treated groups were well-formed, similar to that of control. Strong bitter taste and flavor of Monascus were detected in 5-15% M. rubber DSJ-20-treated groups through sensory evaluation. These results suggest is 3% M. rubber DSJ-20 is desirable leavening concentration for making Jeung-pyun.

홍국을 발효원으로 하여 증편을 제조한 후 식품학적 특성을 관찰하였다. pH 및 산도는 홍국의 첨가량에 따라 대조구와는 다른 양상을 나타내었으나 3-5% 첨가구는 대조구와 유사하였다. 표면색도는 홍국의 첨가량이 많을수록 진한 적색을 나타내었다. Cohesiveness는 홍국 처리구 및 대조구 간에 유의적인 차이를 나타내지 않았다. 내부응집력이 동일한 상태에서 1-2% 홍국 처리구의 hardness, gumminess, chewness가 높은 것은 이들 처리구의 부피증가와 팽화율이 낮기 때문으로, 이는 기공의 크기가 작고 망상구조가 잘 형성되지 않은 것과 관련이 있는 것으로 사료되었다. 3% 이상의 홍국을 첨가한 경우는 기공의 크기가 크고 망상구조가 잘 형성되었으므로 부피 및 팽화도가 높았고, 또한 hardness, gumminess, chewness가 1-2% 홍국 처리구보다 낮고 springness는 높아 대조구와 유사한 경향을 나타내었다. 관능검사 결과, 5% 이상으로 홍국을 첨가하면 홍국 특유의 쓴맛과 진한 향기 때문에 기호성이 매우 감소하였다. 따라서 증편 제조시 새로운 발효원으로 홍국을 사용할 경우, 3%의 홍국(Red yeast rice)을 첨가하는 것이 바람직한 이화학적 조직적 관능적 특성을 나타내는 것으로 사료되었다.
