Extracts from sawdust of Pinus densiflora were showed antifungal activity against Lentinula edodes. It was extracted by hot water and then successively extracted by n-hexane, ethyl acetate, and methanol. The yields of the n-hexane-soluble, ethyl acetatesoluble, methanol-soluble and methanol-insoluble fractions of water extracts were 8.2%, 10.6%, 32.0%, and 49.2%, respectively. The ethyl acetate-soluble fraction showed the greatest antifungal activity against L. edodes: 41.5% inhibition at 1,000 ppm. However, there were not significant differences of antifungal activities between n-hexane-soluble fraction and methanol-soluble fraction at a concentration of 1,000 ppm. The hot water extracts showed 23.5% of antifungal activity against L. edodes at a concentration of 1000 ppm. The four antifungal compounds were separated from ethyl acetate fraction by thin layer chromatography.

광물질 연입필름 2종류(15%의 SiO 계 LDPE, 10%의 zeolite계 LDPE와 기공필름 및 LDPE필름(두께 30)을 이용한 표고버섯의 MAP효과를 조사하고자, 표고버섯을 동일한 방법으로 필름포장한 다음 2와 5에 저장하면서 중량감소율, 표면색과 상품성 지수를 조사하였다. 표고버섯의 MAP시 중량감소율과 상품성에 미치는 포장방법의 영향은 표고버섯의 높은 생리특성으로 인하여 2에서는 인식할 수 없었으나 표면색의 경우는 5의 저온보다는

The effect of drying temperature (30, 40, 50, 60) on chemical components of Shiitake mushroom(Lentinus edodss) was investigate. When compared proximate composition on pileus and stipe of raw and dried materials, all of them were found to be higher in the stipe part than in the pileus part. The major components of organic acid were oxalic, citric, malic, malonic and pyroglutaric acid. The contents of free and total amino acids in pileus and stipe were 3458.4, 7640.2mg% for pilueus; 2298.0, 6171.5mg% for stipe on dry basis, respectively. On the other hand, there was no significant difference in the changes of crude ash and organic acids content of Shiitake mushroom among drying temperatures. But the amount of crude fats was increased and that of reducing sugars was decreased with increase of drying temperature. The contents of crude proteins of pileus part of dried materials were increased with increased drying temperature, but those of stile part were gradually decreased. The contents of free amino acids decreased with increase in drying temperature, but those of total amino acids were gradually increased.

Drying of Shiitake mushroom was investigated to see the effect of temperature, relative humidity of drying air and diameter of the pileus on its rates. The drying rate was increased with the increase of the air temperature and the decrease of the relative humidity. The external color was dark brown at higher drying temperature and higher relative humidity. Exponential and Thompson nodel were found to describe well the raying process of the Shiitake mushroom.
