  • This study was conducted to develop an optimal composite recipe of nutritional cookies containing oak mushroom (Lentinus edodes) powder that has a high preference score. Oak mushroom(Lentinus edodes) is considered a significantly wholesome food. In addition, the dried oak mushroom(Lentinus edodes) has a better flavor and more nutrients than the fresh oak mushroom since vitamins are activated during the drying process. Wheat flour was partially substituted with Lentinus edodes powder to reduce its content. The optimal sensory composite recipe was determined by making iced cookies which have the advantage of long storage, at 3 concentrations of Lentinus edodes powder, yellow sugar and butter, using the central composite design. In addition, the mixing condition of Lentinus edodes powder cookies was optimized by subjecting the cookies to a sensory evaluation and instrumental analysis using the response surface methodology(RSM). The effects of the addition of the three variables on the quality of Lentinus edodes cookies were assessed in terms of texture, color, spread ratio and sensory evaluation. The results of the sensory evaluation produced very significant values for color, appearance, texture, overall quality(p<0.05), flavor(p<0.01) and the results of instrumental analysis showed significant values in lightness(p<0.05), spread ratio, hardness(p<0.01). As a result, the optimal sensory ratio of Lentinus edodes cookies was determined to be Lentinus edodes powder 10.83g, yellow sugar 61.89 g, and butter 120.0 g.

  • Traditional doenjang with Lentinus edodes added at a concentration of 0, 3, 5 and 10% (w/w) was prepared and its physicochemical characteristics were analyzed during fermentation for 6 months. The moisture content, salt level and pH for doenjang were decreased with increasing addition of Lentinus edodes powder, but crude protein content was increased. Among the free sugars, glucose, galactose, arabinose, sucrose and maltose were identified and quantified, with the first two being the major free sugar. Minerals were detected in the order of Na> K> P> Ca> Mg> Fe while the content of Cu, Mn and Zn exhibited little change. The contents of each amino acid of traditional doenjang with added Lentinus edodes, glutamic, leucine and aspartic acids, had a much higher level. In fatty acid compositions, palmitic, stearic, oleic and linoleic acids were analyzed, with oleic acid being the most abundant fatty acid at $56.4{\pm}0.8\sim57.5{\pm}0.5%$ in all the tested samples. GMP and IMP contents of nucleotides and their related compounds were extremely high. It was thought that these substances contributed to the sweet taste of traditional doenjang with added Lentinus edodes. These results showed the applicability and high quality of traditional doenjang with added Lentinus edodes.
