In this study, Sparassis crispa(cauliflower mushroom), which is rich in beta-glucan, was pulverized using ultrafine grinding technology for its potential utilization as a diverse food ingredient. The physical and antioxidant properties of cauliflower mushroom powder were evaluated at various grinding times. The results showed that as the grinding time of cauliflower mushroom increased, the average particle size significantly decreased (p<0.05). Additionally, the water-holding capacity, swelling capacity, and water solubility index of cauliflower mushroom increased significantly(p<0.05). Based on the analysis mentioned above, cauliflower mushroom prepared as a superfine powder for 5 minutes exhibited superior physical and chemical properties as well as antioxidant characteristics and is expected to be widely used in various foods.

This study was conducted to effectively supplement vitamin D and increase the consumption of ear mushroom based on the investigation of the quality characteristics of cookies containing ear mushroom supplemented with vitamin D. Cookies were made of 0%, 1%, 3%, and 5% ear mushroom powder treated by ultraviolet B. Increased addition of ear mushroom powder led to a decrease in the bulk density of the dough as well as a spread factor, color value, and hardness of the cookies. There was no significant difference in the loss rate, but the water content of the dough and cookies was increased. The total polyphenol content of cookies added with 1~5% ear mushroom powder was higher than that of the 0%. The DPPH free radical scavenging activity of cookies added with 5% ear mushroom powder (23.8%) was 2 times higher than that of the 0% (10.9%). The vitamin D2 content of cookies added with 5% ear mushroom powder (835.5 μg/100 g D.W.) was 44 times higher than that of the 0% (19.0 μg/100 g D.W.). Consequently, ear mushroom powder is considered to be suitable for the production of functional cookies because of high values of antioxidant activity and vitamin D2 content.

In this study, a method to produce a fine volatile powder extracted from shiitake mushrooms using spray freeze-drying (SFD) was investigated. The analysis of the water-soluble aromatic compounds was carried out by headspace solid phase micro-extraction (HS-SPME) coupled withgas chromatography-mass spectrometry (GC-MS). Scanning electron microscopy (SEM) and laser particle size analysis were applied to characterizethe physical structure and size distribution of the SFD-derivedparticles. Eleven key volatile compounds were identified in the extracts of shiitake mushroomspre- and post-SFD. Recoveries of aromatic volatiles ranging from 30.9 - 82.9% were observed in the overall flavor profile results from the powder obtained with SFD. SEM analysis demonstrated that the particles of the aromatic powderwere spherical in nature, having highly porous surfaces andmean diameters of 19.3 μm.

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.

본 연구는 느타리, 노랑느타리, 분홍느타리, 버들송이의 건조분말을 이용하여 두부에 적합한 첨가량을 구명하고자 수행되었다. 버섯 첨가량에 따른 두부수율은 대조(무첨가)구에 비해 느타리 3~12%, 노랑느타리 3, 6%, 분홍느타리 3, 6%, 버들송이 3, 6% 첨가시에 수율이 높았고, 버들송이는 9%이상 첨가시 고형이 되지 않았다. 경도는 느타리버섯 3, 6%, 노랑느타리 3%, 분홍느타리 3%, 버들송이 3% 첨가시에 높았다. 버섯의 첨가량이 많을수록 명도는 낮아졌으며, 적색도는 분홍느타리 첨가비율이 높을수록 증가 하였지만 노랑느타리는 황색도가 증가하지 않았다. 버섯두부의 기호도조사결과 느타리버섯은 6~12%, 노랑느타리버섯은 3%, 분홍느타리 3%, 버들송이 3, 6% 첨가시 기호도가 우수한 것으로 나타났다. 이상의 결과 수율과 경도가 높고 기호도가 우수한 두부에 제조에 적합한 버섯의 적정 첨가량은 느타리버섯 6%, 노랑느타리, 분홍느타리, 버들송이 각3%로 판단된다.

검은버섯분말 3, 5, 7%를 첨가하여 국수를 제조한 후 품질을 분석해 련 결과 최고점도와 최종점도 및 노화도는 무처리보다 버섯첨가구에서 모두 낮은 값을 나타내었으며 첨가량이 증가할수록 낮아지는 경향을 나타내었다. 버섯분말첨가량이 증가함에 따라 수분흡수율은 약간 증가하였다. 색도는 버섯분말의 첨가량이 증가함에 따라 분말, 반죽, 국수등 모든 처리구에서 명도는 낮아졌으며, 적색도와 황색도는 증가하는 것으로 나타났다. 버섯국수 조리후 중량과 부피는
