본 연구는 화차의 비율별 제조공정에 따른 이화학적 특성을 조사하기 위하여 수행되었다. 건조전 수분함량은 흑장미나 황국에 비해 녹차가 85.3%로 가장 높았으나 건조 후 수분량은 녹차가 4.55%인데 비해 황국화와 흑장미가 7.42와 7.45%로서 꽃이 수분함량이 높게 나타났다. 조지방은 황국화 5.17%, 흑장미 3.70%, 녹차 2.12%순으로 향이 강한 황국이 가장 높았으며, 총엽록소는 녹차가 499.8(㎎/100g)로 가장 높은데 비해 황국화는 29.8%, 흑장미는 엽록소가 없는 것으로 나타나 엽을 이용하는 부위와 꽃잎을 이용하는 부위의 엽록소 함량 차이가 큰 것으로 나타났다. 조섬유와 조회분은 녹차가 7.59%, 4.82%로 식용꽃에 비해 함량이 높았다. Tannin은 흑장미가 18.99%로 가장 높았으며, 녹차가 14.21%, 황국화가 4.18%순으로 시료간의 성분함량 차이가 컸었다. caffeine은 녹차에서만 3.17%를 함유하고 있었으나 꽃에서는 카페인 성분이 없었다. 칼로리는 전체적으로 비슷한 경향치를 보였으나 흑장미가 가장 낮은 열량을 보였으며, 무기성분함량은 황국이 칼륨 2.57%, 칼슘 0.55%, 마그네슘 0.35%로 전체적으로 녹차와 흑장미보다 높았다. 녹차와 꽃을 혼합한 비율시험에서 처리별 탄닌, 유리아미노산, 전질소, 조지방 및 카페인 변화량은 녹차가 꽃시료보다 함량이 높을 경우 녹차의 혼합비율이 높을수록 비율별 일정하게 증가하는 경향을 보였으나 낮은 경우에는 그 반대 경향을 보였다. This experiment was carried out to investigate the effect of mixed ration on the quality characteristics in manufacture of functional flower tea before dried was 85% and the level of moisture content was higher than the yellow chrysanthemum(C.indicum) and black rose(Rosa hybrida). Yet green tea has 4.55% moisture content after dried, moisture content of flower after dried was higher as the yellow chrysanthemum and black rose have 7.42% and 7.35% moisture content. The yellow chrysanthemum with strong scent has the highest fat among green tea 2.12%, black rose 3.70%, and yellow chrysanthemum 5.17%. Green tea highest chlorophyll as 499.8%(㎎/100g), but yellow chrysanthemum has 29.8% and black rose has none. There was a big difference in chlorophyll between a leaf and a petal. Green tea has higher fiber and lime (7.25%, 4.82%) than esculent flower. There was a large ingredient content difference. Black rose has the highest tannin 18.99%, green tea has 14.21%, and yellow chrysanthemum has 2.12%. Only green tea has caffeine 3.17%, and not in flower. Generally they have similar amount of calorie, but block rose has least. The inorganic ingredient content of yellow chrysanthemum is potassium 2.57%, calcium 0.55%, magnesium 0.35% and green tea mixed-rate was higher and higher, tannin, free amino acid, nitrogen, fat, and caffeine are increased regularly in the ratio test of green tea with flower. But if green tea has less content than material flower, they are opposite.

For the eco-friendly control of fruit rot of fig, disease incidences according to the cultural practices at 51 fig orchards in south coast area of Korea were surveyed in 2002, and the effect of soil mulch and potassium phosphonate on fruit rot of fig was evaluated from 2002 to 2004. Diseased fruits of fig orchards of open field, rain shading, and vinyl house were 33.3%, 7.5%, and 0%, respectively. Diseased fruits were rated at 34.6%, 35.7%, and 27% as the tree spacing of 2 m×2 m, 2m ×3m, and 3 m×4 m, respectively. Among the soil mulching materials, barley straw showed disease incidence of 1.8% and 3.5% of diseased fruits compared to 42.1% and 48% of no mulching in 2002 and 2003, respectively. Diseased fruits in dark paper film mulching were recorded at 4.8% and 12% in 2002 and 2003, respectively, which were lower than those in dark polyethylene film mulching at 11.2% and 26.2%. When potassium phosphonate (1,000 ppm) was sprayed 3 times with 10 days intervals from the beginning of disease occurrence, disease incidences were rated at 3.0% and 2.0% in 2003 and 2004, respectively, which were much lower than those of control at 45.9 % and 39.3%.

맛버섯(Pholiota nameko )은 일명 나도팽나무버섯 으로 도 알려져 있는데 봄부터 가을에 걸쳐 활엽수의 고목, 죽은 가지, 그루터기 위에 다발 발생하는 목재 갈색 부후성 버섯 이며, 한국, 일본, 중국, 북아메리카 등 북반구 일대에 분포 한다. 분류학적으로 주름버섯목(Agaricales ), 독청버섯과 (Strophariaceae ), 비늘버섯속(Pholiota )의 일종으로 갓표면 에는 인피와 점성이 있어 “나메꼬“라는 명칭이 유래되었다. 국내에서는 맛버섯 재배기술에 대한 연구는 거의 이 루어 지지 않고 있는 실정이며, 재배를 하지 않고 있으나 일본에 서는 4번째로 소비가 많이 이루어지는 식용 및 약용으로 쓰 이는 버섯으로 암세포 억제율은 86.5%로 신령버섯, 상황버 섯 다음으로 식용버섯 중 가장 높은 항암력을 갖고 있어 국내 버섯 산업의 안정화를 위하고 버섯 품목의 다양화를 위하고 맛버섯 품종육성과 액체배양 조건구명을 위해 시험을 수행 하였다. 본 실험은 국내외에서 수집한 맛버섯 균주 29계통 을 균사배양 특성 및 병재배시 자실체 특성 검정을 하여 수량 및 품질이 우수한 JNM19003 등 6계통을 선발한 후 단포자 를 분리 교배한 후 JNM19028와 JNM19028 등 25조합을 하여1,700계통을 육성하고, 육성 된 교배계통에 대한 1, 2, 3 차 선발을 하여 그 증에서 갓새깔, 갓의 모양 등 수량을 고려 하여 갓색깔이 노랑과 갈색인 우량계통을 선발하였다. 맛버 섯 대량생산을 위아여 병재배에 접종할 액체종균조제에 알 맞은 조건을 보기위해 액체배지산도는 pH 4, 5, 6, 7, 8을 배 양온도는 20, 22.5, 25, 27.5, 30℃로 처리하여 본 결과 배양 조건별 온도는 22.5℃에서 균사 생육이 좋았고, 균사체 무게 는 2.86 g/ℓ으로 가장 높았으며, pH는 6.0이 좋았으며, pH 가 낮아질수록 균사 생육이 떨어지는 경향이 뚜렷하였다.

팽이버섯(Flammulina velutipes) 생산비 절감을 위한 폐배지 적정 혼합비율

정경주,최덕수,방극필,정기철 한국버섯학회 2009 한국버섯학회지 Vol.7 No.1

These experiments were conducted to find the optimum mixing rate of used media for saving the production cost of Flammulina velutipes. The materials for media formation was used needle-leaf tree sawdust, media that finished 1th cultivation of F. velutipes, corncob meal, and rice bran, wheat bran as nutrition source. We inoculated the F. velutipes in 14 kinds of different media types and checked the spawn growth speed, fruit body quality and quantity. Two nutrition agents, which is rice bran and wheat bran, did not affected the incubation period, but the effective stem number, quality and quantity of fruit body was better at rice bran than wheat bran. The quality of fruit body produced at mixed 20% of used media (needle-leaf tree sawdust 60% + used media 20% + rice bran 20%) was similar to control plot (needle-leaf tree sawdust 80% + rice bran 20%), but the yield was improved 10% than control plot 130g. According as the used-media mixing amount increases, quality and quantity of fruit body became low remarkably. Therefore, the optimum mixing amount of used-media was 20% and it increased 10% of fruitbody yield.

This study was conducted in order to investigate the relationship between pluking season and the quality of steam tea by steaming time during steam tea processing. steaming time of 2nd crop of green leaf were 25, 45, 65 second and 3rd crop of green leaf were 45, 65, 85 second. Steaming leaf and cooling steamed leaf temperature, 3rd crop of green leaf which was abunfand supply of steam were higher 1˚C than 2nd crop of green leaf. Moisture content rate of cooling steamed leaf to green leaf was increased according to longer steaming time, and 2nd crop of green leaf was increased than 3rd crop of green leaf. 3rd crop of green leaf was lower dry moisture content decrease rate. Color of made tea was changed green color into yellow color according to steam time is longer. 25 second of 2nd crop of green leaf and 45 second 3rd crop of green leaf were couldn't taste of mild because of the strong smell of greens, bitterness and astringency. 65 second of 2nd crop of green leaf and 85 second of 3rd crop of green leaf was lusterless and having much sifting, ball lump Optimum steam condition of 2nd crop of green leaf and 3rd of green leaf were each of 45, 65 second consider of shade color, aroma, color of liquor, taste of made tea.
