Abstract

Lentinus edodes (Shiitake mushroom) powder was added to Jeonbyeong dough in an effort to improve the quality and functional properties of the dough. The water absorption increased as the amount of L. edodes powder increased, while the time taken for gelatinization, and the valorimeter value of the final dough, both decreased. The temperature at gelatinization and the highest temperature attained during dough preparation were both similar to control values. The extensogram showed that the resistance of the dough to extension, and the maximum extensibility, both decreased with addition of L. edodes powder. The total contents of crude protein and ash increased with increasing amounts of L. edodes powder, while the dough carbohydrate levels decreased. Addition of the mushroom powder to Jeonbyeong (a kind of Korean traditional snack) decreased dough lightness, and decreased yellowness, as measured on Hunter's color scale. The hardness of Jeonbyeong was increased by adding 15% (w/v) L. edodes powder, but was decreased when 20% (w/v) L. edodes powder was used. The sensory score of Jeonbyeong containing 10% (w/v) L. edodes powder was the highest of all shack tested, in both overall quality characteristics and sensory evaluation.

표고버섯 분말을 첨가한 전병을 제조하여 첨가 수준별 품질특성을 조사하였다. 전병 반죽의 물성 특성 중 흡수율은 표고버섯 분말 첨가량이 많아지면서 증가하였으며, 반죽도달시간과 최고점도는 첨가량에 따라 낮아졌다. 또한 extensogram을 통한 반죽의 energy값은 첨가량과 부의 결과를 보였으며 신장도도 감소하였다. 표고버섯 분말 첨가 전병의 일반성분은 대조구에 비해 수분, 조단백질과 회분의 경우 증가하였고, 탄수화물 함량은 감소하였으며 20% 첨가구의 경우 약간 눅눅한 상태로 전병이 제조되어 전병 제조 시 표고버섯 분말 첨가량은 20%를 넘지 않는 것이 적당할 것으로 판단된다. 색도를 분석한 결과 L값과 b값은 첨가량이 증가하면서 유의적으로 감소하였고, a값은 10% 이상 첨가구에서 다소 증가하는 결과를 보였다. 또한 10% 이상 첨가시 기존 대조구와 현저한 색의 차이를 보이는 것으로 나타났다. Rheometer를 이용한 물성 측정 결과 경도(hardness)는 15%까지 증가하다 20% 첨가구에서 크게 감소하였는데, 이는 20% 시료의 조직이 눅눅한 상태의 결과와 일치하였다. 최대 하중값과 파단점도 경도와 비슷한 결과를 보여 대조구에 비해 증가하였다. 시료별 관능검사 결과는 색(color), 향(flavor), 맛(taste)과 전반적인 기호도(overall acceptability) 등 모든 항목에서 10% 첨가구가 가장 높은 점수를 받았으며 15% 이상 첨가 할 때 기호도가 조금씩 감소하는 것으로 나타나 전병 제조 할 때 최적의 표고버섯 분말 첨가량은 10% 수준이 될 것으로 판단된다.
