Pine mushroom is excellent for its unique smell, nutrients and functional factors. The quality characteristics of Demi-glace sauce made from pine mushrooms that have not been used despite their value as good ingredients and mushrooms that have been added to various kinds of sauce were examined by differing pine mushroom and mushroom powder in stock. The more pine mushroom and mushroom powder was added, the content of minerals increased; however, the content of moisture decreased. Overall, viscosity was increased. The content of each mineral varied in proportion to pine mushroom and mushroom powder contents level. Sensory evaluation of pine mushroom added to demi-glace sauce showed difference in sweetness, savory taste overall. 0.2% addition of sweetness, 0.3% addition of savory taste, 0.2% and 0.3% addition of overall acceptability appeared as the best estimation. Specially, 0.2% addition was the highest in salty taste and color. As the two mushroom powder contents was increased, tastes of demi-glace sauce were not increased; rather, the appropriate amount of addition existed.

Pine mushroom (Tricholoma matsutake) is one of the most profitable forest products in Korea. We postulated a hypothesis that a high rate of returns to labor input could make the harvest of pine mushroom off the optimum level. In the view of developing a sustainable production strategy for pine mushroom producers, production of pine mushroom collectors and pine mushroom growth function were estimated using maximum entropy method. Annual pine mushroom production and labor input were the data used in the estimation of production function of pine mushroom collectors and pine mushroom growth function. The level of sustainable maximum production derived from the estimated function. The production function estimated shows that production of pine mushroom is affected more by the resource of pine mushroom stocked in the forests than by labor that households put in forestry business. The production function of mushroom collectors and the estimated growth function indicate that pine mushroom harvests for the period of 2005-2011 did not reach the potential level of maximum sustainable production. Therefore, we suggest that pine mushroom harvest should be controlled until the resource stock of pine mushroom in the forests increases to the level of maximum sustainable production.

This study investigated the rheological and sensory characteristics of pickle with frozen pine mushroom. P3(Developed pickle seasoning) was the best by preference among three kinds of pine mushroom pickle seasoning. For flavor and functionality, pine mushroom pickle was processed by using three kinds of method(P3-1: P3+cinnamon 10 g, P3-2: P3+licorice 10 g and P3-3: P3+licorice 5 g+cinnamon 5 g). As a result, the product from P3-3(P3+licorice 5 g+cinnamon 5 g) was the best preferred pine mushroom pickle. The pH value of P3-3 was 2.15, 42.9 degrees Brix, and its color value was L(54.65), a(-1.61), b(17.87). Its texture level was higher than that of other products, but it would be lowered on storage. Until the 28th day of storage, microorganisms in pine mushroom pickle seasoning were detected less than 30 CFU/mL.

This study was conducted to investigate rheological and sensory characteristics of Sulgidduk added with pine mushroom powder. The moisture content of the Sulgidduk ranged from 34.79 to 36.93%. Increasing the amount of pine mushroom powder in the Sulgidduk tended to decrease the pH value, but to increase the $brix^{\circ}$ value. Increasing the amount of pine mushroom powder in the Sulgidduk tended to decrease the lightness(L) in Hunter color value, but to increase the redness(a) and yellowness(b). For the textural characteristics, the addition of pine mushroom powder decreased the adhesiveness and springiness. In sensory evaluation, the addition of 3% pine mushroom powder had the best score in appearance, odor, taste and overall preference. Therefore, this results suggest that adding 3% pine mushroom powder would be feasible for making pine mushroom Sulgidduk.

This study is based on the utilization of pine mushroom for processing products by development of pine mushroom Jung-Gwa. The results were summarized as follows: Pine mushroom Jung-Gwa were prepared with four different amounts (20, 30, 40, 50%) of honey. Pine mushroom Jung-Gwa color value was the highest by 20% soaking honey-water product and 40% soaking honey-water product was the lowest. Strength and hardness of 20% soaking honey-water product was the highest. Appearance to product of 50% soaking honey-water was the highest preference by all age of except 20's. The honey content of more and more external appearance preference was became higher. Product of 40% soaking honey-water was best by flavor of pine mushroom Jung-Gwa. A sugary tastes comparison 50% soaking honey water to 40% soaking honey water was not distinction. The texture was appeared a statistically significant difference by products of 20%, 30% soaking honey-water. Product of 20% soaking honey-water was favorite in 20's and product of 30% soaking honey-water was favorite in 30's. In overall preference test for pine mushroom Jung-Gwa of 40% soaking honey water was preferred by all age. Oligosaccharide helped geriatric diseases and cheaper. Thus this study used oligosaccharide but the result was not a statistically significant difference of pine mushroom Jung-Gwa products quality by comparison honey-water to oligosaccharide. Therefore oligosaccharide utilization products was thought worth a lot more by processing price and functional.

Changes in flavor compounds in pine mushroom (Tricholoma matsutake) liquor added with pine tree chips were analyzed using gas chromatography/mass spectrometry. While three flavor compounds were detected in the control, fifteen were detected in the pine mushroom liquor added with pine tree chips. After eight-weeks of aging, the relative concentrations of β-fenchyl alcohol, 2-octanol, and methyl cinnamate, which are distinctive flavor characteristics of the pine mushroom, increased by 67.57%, 2.14%, and 0.94%, respectively, when pine tree chips were added (5%). Principal component analysis revealed that although flavor characteristics of the pine mushroom liquor were affected by the increased production of β-fenchyl alcohol due to the addition of pine tree chips, the aging time exerted a greater influence on flavor.
