표고 재배용 액체종균 배지조성은 대두박분 배지에 입도가 850 μm이하인 참나무분 0.3% 첨가 시 균사체 건중량이 457 mg으로 다소 높았으며, Laccase 활성도는 참나무분 첨가율별 대두박분 배지에 큰 차이가 없었으나 Cellulase 활성도는 CMC Agar Plate에서 26.4 mm로서 참나무분 첨가율별 대두박분 액체종균 처리구중에서 가장 우수하였다. 액체종균의 통기량이 증가할수록 이산화탄소 발생량이 증가하여 배양 7일째 최대치를 나타내었으며 균사체 건중량은 10일째 3.0g/l로 가장 우수한 것으로 나타났다. 통기량이 증가할수록 이산화탄소 발생량, 균사체 건중량도 증가하였으며 0.6vvm 처리시 배지 증발율이 32%, 균사체 건중량이 3.5g/l로서 우수하였다. 선발된 액체종균을 톱밥 종균과 생산성 비교를 위하여 톱밥재배 봉지배지에 시험한 결과, 액체종균의 생육기간이 톱밥종균에 비해 1일 지연되었으나, 봉지당 유효 개체수와 수량에는 유의적인 차이가 없는 것으로 나타났다.

The purpose of this study was to bake sweet rice muffins with oak mushroom (Lentinus edodes) powder. The process included substituting sweet rice flour for cake flour and adding oak mushroom powder. This study determined the optimal mixing conditions of oak mushroom muffins by adjusting the amounts of oak mushroom powder, whole eggs, and soybean oil. The mixing conditions for the oak mushroom muffins included 3 categories: oak mushroom powder (X1), whole eggs (X2), and soybean oil (X3) by Central Composite Design (CCD) which was optimized by Response Surface Methodology (RSM). Oak mushroom muffin formulation was optimized using rheology. Yellowness (p〈0.001) and redness (p〈0.05) displayed a linear model pattern, whereas lightness (p〈0.05) was represented by a quadratic model. Among the sensory properties, variables that appeared to show significant values such as appearance (p〈0.5), texture (p〈0.5), and overall quality (p〈0.5) were used to identify optimums. The result of mechanical properties showed significant values in gumminess (p〈0.5) and chewiness (p〈0.5). The numerical and graphical methods used in this study determined that the optimum formulation for oak mushroom powder sweet rice muffins was 8.75 g of oak mushroom powder, 235.95 g of whole eggs, and 19.93 g of soybean oil.
